# ARM64 Support for FoundationDB Integration
This document explains how to run FoundationDB integration tests on ARM64 systems (Apple Silicon M1/M2/M3 Macs).
## Problem
The official FoundationDB Docker images (`foundationdb/foundationdb:7.1.61`) are only available for `linux/amd64` architecture. When running on ARM64 systems, you'll encounter "Illegal instruction" errors. Apple now publishes official ARM64 Debian packages (starting with 7.4.5), which this repo downloads directly for native workflows.
## Solutions
We provide **three different approaches** to run FoundationDB on ARM64:
### 1. 🚀 ARM64 Native (Recommended for Development)
**Pros:** Native performance, no emulation overhead
**Cons:** Requires downloading ~100MB of FoundationDB packages on first run
```bash
# Build and run ARM64-native FoundationDB from source
make setup-arm64
make test-arm64
```
This approach:
- Downloads the official FoundationDB 7.4.5 ARM64 packages
- Takes ~2-3 minutes on first run (no source compilation)
- Provides native performance
- Uses `docker-compose.arm64.yml`
### 2. 🐳 x86 Emulation (Quick Setup)
**Pros:** Fast setup, uses official images
**Cons:** Slower runtime performance due to emulation
```bash
# Run x86 images with Docker emulation
make setup-emulated
make test-emulated
```
This approach:
- Uses Docker's x86 emulation
- Quick setup with official images
- May have performance overhead
- Uses standard `docker-compose.yml` with platform specification
### 3. 📝 Mock Testing (Fastest)
**Pros:** No dependencies, always works, fast execution
**Cons:** Doesn't test real FoundationDB integration
```bash
# Run mock tests (no FoundationDB cluster needed)
make test-mock
make test-reliable
```
## Files Overview
| File | Purpose |
|------|---------|
| `docker-compose.yml` | Standard setup with platform specification |
| `docker-compose.arm64.yml` | ARM64-native setup with source builds |
| `Dockerfile.fdb-arm64` | Multi-stage build for ARM64 FoundationDB |
| `README.ARM64.md` | This documentation |
## Performance Comparison
| Approach | Setup Time | Runtime Performance | Compatibility |
|----------|------------|-------------------|---------------|
| ARM64 Native | 2-3 min | ⭐⭐⭐⭐⭐ | ARM64 only |
| x86 Emulation | 2-3 min | ⭐⭐⭐ | ARM64 + x86 |
| Mock Testing | < 1 min | ⭐⭐⭐⭐⭐ | Any platform |
## Quick Start Commands
```bash
# For ARM64 Mac users - choose your approach:
# Option 1: ARM64 native (best performance)
make clean && make setup-arm64
# Option 2: x86 emulation (faster setup)
make clean && make setup-emulated
# Option 3: Mock testing (no FDB needed)
make test-mock
# Clean up everything
make clean
```
## Troubleshooting
### Build Timeouts
If ARM64 builds timeout, increase Docker build timeout:
```bash
export DOCKER_BUILDKIT=1
export BUILDKIT_PROGRESS=plain
make setup-arm64
```
### Memory Issues
ARM64 builds require significant memory:
- Increase Docker memory limit to 8GB+
- Close other applications during build
### Platform Detection
Verify your platform:
```bash
docker info | grep -i arch
uname -m # Should show arm64
```
## CI/CD Recommendations
- **Development**: Use `make test-mock` for fast feedback
- **ARM64 CI**: Use `make setup-arm64`
- **x86 CI**: Use `make setup` (standard)
- **Multi-platform CI**: Run both depending on runner architecture
## Architecture Details
The ARM64 solution now uses the official FoundationDB 7.4.5 aarch64 packages:
1. **Builder Stage**: Downloads prebuilt FoundationDB client libraries
- Uses Debian-based Go image for compiling SeaweedFS
- Verifies SHA256 checksums before installing the deb package
2. **Runtime Stage**: Copies the already-installed artifacts
- SeaweedFS runtime layers reuse the validated libraries
- FoundationDB server containers install the prebuilt server + client packages with checksum verification
This keeps the setup time short while preserving native ARM64 performance and strong supply-chain guarantees.

# FoundationDB Integration Testing
This directory contains integration tests and setup scripts for the FoundationDB filer store in SeaweedFS.
## Quick Start
```bash
# ✅ GUARANTEED TO WORK - Run reliable tests (no FoundationDB dependencies)
make test-reliable # Validation + Mock tests
# Run individual test types
make test-mock # Mock FoundationDB tests (always work)
go test -v ./validation_test.go # Package structure validation
# 🐳 FULL INTEGRATION (requires Docker + FoundationDB dependencies)
make setup # Start FoundationDB cluster + SeaweedFS
make test # Run all integration tests
make test-simple # Simple containerized test environment
# Clean up
make clean # Clean main environment
make clean-simple # Clean simple test environment
# 🍎 ARM64 / APPLE SILICON SUPPORT
make setup-arm64 # Native ARM64 FoundationDB (builds from source)
make setup-emulated # x86 emulation (faster setup)
make test-arm64 # Test with ARM64 native
make test-emulated # Test with x86 emulation
```
### Test Levels
1. **✅ Validation Tests** (`validation_test.go`) - Always work, no dependencies
2. **✅ Mock Tests** (`mock_integration_test.go`) - Test FoundationDB store logic with mocks
3. **⚠️ Real Integration Tests** (`foundationdb_*_test.go`) - Require actual FoundationDB cluster
### ARM64 / Apple Silicon Support
**🍎 For M1/M2/M3 Mac users:** FoundationDB's official Docker images are AMD64-only. We provide three solutions:
- **Native ARM64** (`make setup-arm64`) - Downloads official FoundationDB ARM64 packages and builds SeaweedFS natively (≈2-3 min setup, best performance)
- **x86 Emulation** (`make setup-emulated`) - Uses Docker emulation (fast setup, slower runtime)
- **Mock Testing** (`make test-mock`) - No FoundationDB needed (instant, tests logic only)
The ARM64 setup automatically builds both FoundationDB and SeaweedFS from source using `docker-compose.arm64.yml` and dedicated ARM64 Dockerfiles. No pre-built images required!
📖 **Detailed Guide:** See [README.ARM64.md](README.ARM64.md) for complete ARM64 documentation.
## Test Environment
The test environment includes:
- **3-node FoundationDB cluster** (fdb1, fdb2, fdb3) for realistic distributed testing
- **Database initialization service** (fdb-init) that configures the cluster
- **SeaweedFS service** configured to use the FoundationDB filer store
- **Automatic service orchestration** with proper startup dependencies
## Test Structure
### Integration Tests
#### `foundationdb_integration_test.go`
- Basic CRUD operations (Create, Read, Update, Delete)
- Directory operations and listing:
- `ListDirectoryEntries` - List all entries in a directory
- `ListDirectoryPrefixedEntries` - List entries matching a prefix
- `DeleteFolderChildren` - Bulk deletion of directory contents
- Transaction handling (begin, commit, rollback)
- Key-Value operations
- Large entry handling with compression
- Error scenarios and edge cases
**Note:** These tests operate at the filer store level, testing the metadata index operations that underpin S3 bucket listing and directory tree operations.
#### `foundationdb_concurrent_test.go`
- Concurrent insert operations across multiple goroutines
- Concurrent read/write operations on shared files
- Concurrent transaction handling with conflict resolution
- Concurrent directory operations
- Concurrent key-value operations
- Stress testing under load
#### `test_fdb_s3.sh` - End-to-End S3 Integration Tests
- **S3 bucket creation** - Create buckets via S3 API
- **S3 file upload** - Upload files to buckets
- **S3 bucket listing** (`aws s3 ls`) - **Validates listing operations work correctly**
- **S3 file download** - Retrieve and verify file contents
- **S3 file deletion** - Delete objects and verify removal
- **FoundationDB backend verification** - Confirms data is stored in FDB
- **Filer directory operations** - Direct filer API calls for directory creation/listing
**This test validates the complete S3 workflow including the listing operations that were problematic in earlier versions.**
#### Unit Tests (`weed/filer/foundationdb/foundationdb_store_test.go`)
- Store initialization and configuration
- Key generation and directory prefixes
- Error handling and validation
- Performance benchmarks
- Configuration validation
## Configuration
### Environment Variables
The tests can be configured using environment variables:
```bash
export FDB_CLUSTER_FILE=/var/fdb/config/fdb.cluster
export WEED_FOUNDATIONDB_ENABLED=true
export WEED_FOUNDATIONDB_API_VERSION=740
export WEED_FOUNDATIONDB_TIMEOUT=10s
```
#### Docker Compose Environment Variables
The `docker-compose.yml` file supports the following optional environment variables with sensible defaults:
```bash
# FoundationDB image (default: foundationdb/foundationdb:7.1.61)
export FOUNDATIONDB_IMAGE=foundationdb/foundationdb:7.1.61
# FoundationDB port (default: 4500)
export FDB_PORT=4500
# FoundationDB cluster file contents (default: docker:docker@fdb1:4500,fdb2:4500,fdb3:4500)
export FDB_CLUSTER_FILE_CONTENTS="docker:docker@fdb1:4500,fdb2:4500,fdb3:4500"
# SeaweedFS image (default: chrislusf/seaweedfs:latest)
export SEAWEEDFS_IMAGE=chrislusf/seaweedfs:latest
```
**Note:** These variables are optional. If not set, the docker-compose will use the default values shown above, allowing `docker-compose up` to work out-of-the-box without any `.env` file or manual configuration.
### Docker Compose Configuration
The `docker-compose.yml` sets up:
1. **FoundationDB Cluster**: 3 coordinating nodes with data distribution
2. **Database Configuration**: Single SSD storage class for testing
3. **SeaweedFS Integration**: Automatic filer store configuration
4. **Volume Persistence**: Data persists between container restarts
### Test Configuration Files
- `filer.toml`: FoundationDB filer store configuration
- `s3.json`: S3 API credentials for end-to-end testing
- `Makefile`: Test automation and environment management
## Test Commands
### Setup Commands
```bash
make setup # Full environment setup
make dev-fdb # Just FoundationDB cluster
make install-deps # Check dependencies
make check-env # Validate configuration
```
### Test Commands
```bash
make test # All tests
make test-unit # Go unit tests
make test-integration # Integration tests
make test-e2e # End-to-end S3 tests (includes S3 bucket listing)
make test-crud # Basic CRUD operations
make test-concurrent # Concurrency tests
make test-benchmark # Performance benchmarks
```
#### S3 and Listing Operation Coverage
**✅ Currently Tested:**
- **S3 bucket listing** (`aws s3 ls`) - Validated in `test_fdb_s3.sh`
- **Directory metadata listing** (`ListDirectoryEntries`) - Tested in `foundationdb_integration_test.go`
- **Prefix-based listing** (`ListDirectoryPrefixedEntries`) - Tested in `foundationdb_integration_test.go`
- **Filer directory operations** - Basic filer API calls in `test_fdb_s3.sh`
- **Metadata index operations** - All CRUD operations on directory entries
**⚠️ Limited/Future Coverage:**
- **Recursive tree operations** - Not explicitly tested (e.g., `weed filer.tree` command)
- **Large directory stress tests** - Listings with thousands of entries not currently benchmarked
- **Concurrent listing operations** - Multiple simultaneous directory listings under load
- **S3 ListObjectsV2 pagination** - Large bucket listing with continuation tokens
**Recommendation:** If experiencing issues with S3 listing operations in production, add stress tests for large directories and concurrent listing scenarios to validate FoundationDB's range scan performance at scale.
### Debug Commands
```bash
make status # Show service status
make logs # Show all logs
make logs-fdb # FoundationDB logs only
make logs-seaweedfs # SeaweedFS logs only
make debug # Debug information
```
### Cleanup Commands
```bash
make clean # Stop services and cleanup
```
## Test Data
Tests use isolated directory prefixes to avoid conflicts:
- **Unit tests**: `seaweedfs_test`
- **Integration tests**: `seaweedfs_test`
- **Concurrent tests**: `seaweedfs_concurrent_test_<timestamp>`
- **E2E tests**: `seaweedfs` (default)
## Expected Test Results
### Performance Expectations
Based on FoundationDB characteristics:
- **Single operations**: < 10ms latency
- **Batch operations**: High throughput with transactions
- **Concurrent operations**: Linear scaling with multiple clients
- **Directory listings**: Efficient range scans
### Reliability Expectations
- **ACID compliance**: All operations are atomic and consistent
- **Fault tolerance**: Automatic recovery from node failures
- **Concurrency**: No data corruption under concurrent load
- **Durability**: Data persists across restarts
## Troubleshooting
### Common Issues
1. **FoundationDB Connection Errors**
```bash
# Check cluster status
make status
# Verify cluster file
docker-compose exec fdb-init cat /var/fdb/config/fdb.cluster
```
2. **Test Failures**
```bash
# Check service logs
make logs-fdb
make logs-seaweedfs
# Run with verbose output
go test -v -tags foundationdb ./...
```
3. **Performance Issues**
```bash
# Check cluster health
docker-compose exec fdb-init fdbcli --exec 'status details'
# Monitor resource usage
docker stats
```
4. **Docker Issues**
```bash
# Clean Docker state
make clean
docker system prune -f
# Restart from scratch
make setup
```
### Debug Mode
Enable verbose logging for detailed troubleshooting:
```bash
# SeaweedFS debug logs
WEED_FILER_OPTIONS_V=2 make test
# FoundationDB debug logs (in fdbcli)
configure new single ssd; status details
```
### Manual Testing
For manual verification:
```bash
# Start environment
make dev-fdb
# Connect to FoundationDB
docker-compose exec fdb-init fdbcli
# FDB commands:
# status - Show cluster status
# getrange "" \xFF - Show all keys
# getrange seaweedfs seaweedfs\xFF - Show SeaweedFS keys
```
### Listing Operations Return Empty Results
**Symptoms:** Uploads succeed, direct file reads work, but listing operations (`aws s3 ls`, `s3.bucket.list`, `weed filer.ls/tree`) return no results.
**Test Coverage:** The `test_fdb_s3.sh` script explicitly tests S3 bucket listing (`aws s3 ls`) to catch this class of issue. Integration tests cover the underlying `ListDirectoryEntries` operations.
**Diagnostic steps:**
```bash
# 1. Verify writes reached FoundationDB
docker-compose exec fdb-init fdbcli
> getrange seaweedfs seaweedfs\xFF
# If no keys appear, writes aren't reaching the store
# 2. Check SeaweedFS volume assignment
curl http://localhost:9333/cluster/status
# Look for "AssignVolume" errors in logs:
make logs-seaweedfs | grep -i "assignvolume\|writable"
# 3. Verify filer health and configuration
curl http://localhost:8888/statistics/health
make logs-seaweedfs | grep -i "store\|foundationdb"
```
**Interpretation:**
- No SeaweedFS keys in FDB: Directory index writes failing; check filer logs for write errors
- AssignVolume errors: Volume assignment blocked; check master status and disk space
- Filer health errors: Configuration or connectivity issue; restart services and verify filer.toml
**Recovery:**
- If fresh data: restart services (`make clean && make setup`)
- If production data: ensure volume assignment works, check disk space on data nodes
## CI Integration
For continuous integration:
```bash
# CI test suite
make ci-test # Unit + integration tests
make ci-e2e # Full end-to-end test suite
```
The tests are designed to be reliable in CI environments with:
- Automatic service startup and health checking
- Timeout handling for slow CI systems
- Proper cleanup and resource management
- Detailed error reporting and logs
## Performance Benchmarks
Run performance benchmarks:
```bash
make test-benchmark
# Sample expected results:
# BenchmarkFoundationDBStore_InsertEntry-8 1000 1.2ms per op
# BenchmarkFoundationDBStore_FindEntry-8 5000 0.5ms per op
# BenchmarkFoundationDBStore_KvOperations-8 2000 0.8ms per op
```
## Contributing
When adding new tests:
1. Use the `//go:build foundationdb` build tag
2. Follow the existing test structure and naming
3. Include both success and error scenarios
4. Add appropriate cleanup and resource management
5. Update this README with new test descriptions

# FoundationDB Filer Store Configuration Reference
This document provides comprehensive configuration options for the FoundationDB filer store.
## Configuration Methods
### 1. Configuration File (filer.toml)
```toml
[foundationdb]
enabled = true
cluster_file = "/etc/foundationdb/fdb.cluster"
api_version = 740
timeout = "5s"
max_retry_delay = "1s"
directory_prefix = "seaweedfs"
```
### 2. Environment Variables
All configuration options can be set via environment variables with the `WEED_FOUNDATIONDB_` prefix:
```bash
export WEED_FOUNDATIONDB_ENABLED=true
export WEED_FOUNDATIONDB_CLUSTER_FILE=/etc/foundationdb/fdb.cluster
export WEED_FOUNDATIONDB_API_VERSION=740
export WEED_FOUNDATIONDB_TIMEOUT=5s
export WEED_FOUNDATIONDB_MAX_RETRY_DELAY=1s
export WEED_FOUNDATIONDB_DIRECTORY_PREFIX=seaweedfs
```
### 3. Command Line Arguments
While not directly supported, configuration can be specified via config files passed to the `weed` command.
## Configuration Options
### Basic Options
| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `enabled` | boolean | `false` | Enable the FoundationDB filer store |
| `cluster_file` | string | `/etc/foundationdb/fdb.cluster` | Path to FoundationDB cluster file |
| `api_version` | integer | `740` | FoundationDB API version to use |
### Connection Options
| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `timeout` | duration | `5s` | Transaction timeout duration |
| `max_retry_delay` | duration | `1s` | Maximum delay between retries |
### Storage Options
| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `directory_prefix` | string | `seaweedfs` | Directory prefix for key organization |
## Configuration Examples
### Development Environment
```toml
[foundationdb]
enabled = true
cluster_file = "/var/fdb/config/fdb.cluster"
api_version = 740
timeout = "10s"
max_retry_delay = "2s"
directory_prefix = "seaweedfs_dev"
```
### Production Environment
```toml
[foundationdb]
enabled = true
cluster_file = "/etc/foundationdb/fdb.cluster"
api_version = 740
timeout = "30s"
max_retry_delay = "5s"
directory_prefix = "seaweedfs_prod"
```
### High-Performance Setup
```toml
[foundationdb]
enabled = true
cluster_file = "/etc/foundationdb/fdb.cluster"
api_version = 740
timeout = "60s"
max_retry_delay = "10s"
directory_prefix = "sw" # Shorter prefix for efficiency
```
### Path-Specific Configuration
Configure different FoundationDB settings for different paths:
```toml
# Default configuration
[foundationdb]
enabled = true
cluster_file = "/etc/foundationdb/fdb.cluster"
directory_prefix = "seaweedfs_main"
# Backup path with different prefix
[foundationdb.backup]
enabled = true
cluster_file = "/etc/foundationdb/fdb.cluster"
directory_prefix = "seaweedfs_backup"
location = "/backup"
timeout = "120s"
# Archive path with extended timeouts
[foundationdb.archive]
enabled = true
cluster_file = "/etc/foundationdb/fdb.cluster"
directory_prefix = "seaweedfs_archive"
location = "/archive"
timeout = "300s"
max_retry_delay = "30s"
```
## Configuration Validation
### Required Settings
The following settings are required for FoundationDB to function:
1. `enabled = true`
2. `cluster_file` must point to a valid FoundationDB cluster file
3. `api_version` must match your FoundationDB installation
### Validation Rules
- `api_version` must be between 600 and 740
- `timeout` must be a valid duration string (e.g., "5s", "30s", "2m")
- `max_retry_delay` must be a valid duration string
- `cluster_file` must exist and be readable
- `directory_prefix` must not be empty
### Error Handling
Invalid configurations will result in startup errors:
```
FATAL: Failed to initialize store for foundationdb: invalid timeout duration
FATAL: Failed to initialize store for foundationdb: failed to open FoundationDB database
FATAL: Failed to initialize store for foundationdb: cluster file not found
```
## Performance Tuning
### Timeout Configuration
| Use Case | Timeout | Max Retry Delay | Notes |
|----------|---------|-----------------|-------|
| Interactive workloads | 5s | 1s | Fast response times |
| Batch processing | 60s | 10s | Handle large operations |
| Archive operations | 300s | 30s | Very large data sets |
### Connection Pool Settings
FoundationDB automatically manages connection pooling. No additional configuration needed.
### Directory Organization
Use meaningful directory prefixes to organize data:
```toml
# Separate environments
directory_prefix = "prod_seaweedfs" # Production
directory_prefix = "staging_seaweedfs" # Staging
directory_prefix = "dev_seaweedfs" # Development
# Separate applications
directory_prefix = "app1_seaweedfs" # Application 1
directory_prefix = "app2_seaweedfs" # Application 2
```
## Security Configuration
### Cluster File Security
Protect the FoundationDB cluster file:
```bash
# Set proper permissions
sudo chown root:seaweedfs /etc/foundationdb/fdb.cluster
sudo chmod 640 /etc/foundationdb/fdb.cluster
```
### Network Security
FoundationDB supports TLS encryption. Configure in the cluster file:
```
description:cluster_id@tls(server1:4500,server2:4500,server3:4500)
```
### Access Control
Use FoundationDB's built-in access control mechanisms when available.
## Monitoring Configuration
### Health Check Settings
Configure health check timeouts appropriately:
```toml
[foundationdb]
enabled = true
timeout = "10s" # Reasonable timeout for health checks
```
### Logging Configuration
Enable verbose logging for troubleshooting:
```bash
# Start SeaweedFS with debug logs
WEED_FOUNDATIONDB_ENABLED=true weed -v=2 server -filer
```
## Migration Configuration
### From Other Filer Stores
When migrating from other filer stores:
1. Configure both stores temporarily
2. Use path-specific configuration for gradual migration
3. Migrate data using SeaweedFS tools
```toml
# During migration - keep old store for reads
[leveldb2]
enabled = true
dir = "/old/filer/data"
# New writes go to FoundationDB
[foundationdb.migration]
enabled = true
location = "/new"
cluster_file = "/etc/foundationdb/fdb.cluster"
```
## Backup Configuration
### Metadata Backup Strategy
```toml
# Main storage
[foundationdb]
enabled = true
directory_prefix = "seaweedfs_main"
# Backup storage (different cluster recommended)
[foundationdb.backup]
enabled = true
cluster_file = "/etc/foundationdb/backup_fdb.cluster"
directory_prefix = "seaweedfs_backup"
location = "/backup"
```
## Container Configuration
### Docker Environment Variables
```bash
# Docker environment
WEED_FOUNDATIONDB_ENABLED=true
WEED_FOUNDATIONDB_CLUSTER_FILE=/var/fdb/config/fdb.cluster
WEED_FOUNDATIONDB_API_VERSION=740
```
### Kubernetes ConfigMap
```yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: seaweedfs-config
data:
filer.toml: |
[foundationdb]
enabled = true
cluster_file = "/var/fdb/config/cluster_file"
api_version = 740
timeout = "30s"
max_retry_delay = "5s"
directory_prefix = "k8s_seaweedfs"
```
## Troubleshooting Configuration
### Debug Configuration
```toml
[foundationdb]
enabled = true
cluster_file = "/etc/foundationdb/fdb.cluster"
timeout = "60s" # Longer timeouts for debugging
max_retry_delay = "10s"
directory_prefix = "debug_seaweedfs"
```
### Test Configuration
```toml
[foundationdb]
enabled = true
cluster_file = "/tmp/fdb.cluster" # Test cluster
timeout = "5s"
directory_prefix = "test_seaweedfs"
```
## Configuration Best Practices
### 1. Environment Separation
Use different directory prefixes for different environments:
- Production: `prod_seaweedfs`
- Staging: `staging_seaweedfs`
- Development: `dev_seaweedfs`
### 2. Timeout Settings
- Interactive: 5-10 seconds
- Batch: 30-60 seconds
- Archive: 120-300 seconds
### 3. Cluster File Management
- Use absolute paths for cluster files
- Ensure proper file permissions
- Keep backup copies of cluster files
### 4. Directory Naming
- Use descriptive prefixes
- Include environment/application identifiers
- Keep prefixes reasonably short for efficiency
### 5. Error Handling
- Configure appropriate timeouts
- Monitor retry patterns
- Set up alerting for configuration errors
## Configuration Testing
### Validation Script
```bash

directory_prefix = "sw" # Shorter prefix for efficiency
```
### OS-Level Tuning
```bash
# Increase file descriptor limits
echo "* soft nofile 65536" >> /etc/security/limits.conf
echo "* hard nofile 65536" >> /etc/security/limits.conf
# Adjust network parameters
echo "net.core.rmem_max = 134217728" >> /etc/sysctl.conf
echo "net.core.wmem_max = 134217728" >> /etc/sysctl.conf
sysctl -p
```
## Monitoring and Maintenance
### Health Checks
```bash
# FoundationDB cluster health
fdbcli --exec 'status'
fdbcli --exec 'status details'

# FoundationDB Filer Store
This package provides a FoundationDB-based filer store for SeaweedFS, offering ACID transactions and horizontal scalability.
## Features
- **ACID Transactions**: Strong consistency guarantees with full ACID properties
- **Horizontal Scalability**: Automatic data distribution across multiple nodes
- **High Availability**: Built-in fault tolerance and automatic failover
- **Efficient Directory Operations**: Optimized for large directory listings
- **Key-Value Support**: Full KV operations for metadata storage
- **Compression**: Automatic compression for large entry chunks
## Installation
### Prerequisites
1. **FoundationDB Server**: Install and configure a FoundationDB cluster
2. **FoundationDB Client Libraries**: Install libfdb_c client libraries
3. **Go Build Tags**: Use the `foundationdb` build tag when compiling
### Building SeaweedFS with FoundationDB Support
```bash
go build -tags foundationdb -o weed
```
## Configuration
### Basic Configuration
Add the following to your `filer.toml`:
```toml
[foundationdb]
enabled = true
cluster_file = "/etc/foundationdb/fdb.cluster"
api_version = 740
timeout = "5s"
max_retry_delay = "1s"
directory_prefix = "seaweedfs"
```
### Configuration Options
| Option | Description | Default | Required |
|--------|-------------|---------|----------|
| `enabled` | Enable FoundationDB filer store | `false` | Yes |
| `cluster_file` | Path to FDB cluster file | `/etc/foundationdb/fdb.cluster` | Yes |
| `api_version` | FoundationDB API version | `740` | No |
| `timeout` | Operation timeout duration | `5s` | No |
| `max_retry_delay` | Maximum retry delay | `1s` | No |
| `directory_prefix` | Directory prefix for organization | `seaweedfs` | No |
### Path-Specific Configuration
For path-specific filer stores:
```toml
[foundationdb.backup]
enabled = true
cluster_file = "/etc/foundationdb/fdb.cluster"
directory_prefix = "seaweedfs_backup"
location = "/backup"
```
## Environment Variables
Configure via environment variables:
```bash
export WEED_FOUNDATIONDB_ENABLED=true
export WEED_FOUNDATIONDB_CLUSTER_FILE=/etc/foundationdb/fdb.cluster
export WEED_FOUNDATIONDB_API_VERSION=740
export WEED_FOUNDATIONDB_TIMEOUT=5s
export WEED_FOUNDATIONDB_MAX_RETRY_DELAY=1s
export WEED_FOUNDATIONDB_DIRECTORY_PREFIX=seaweedfs
```
## FoundationDB Cluster Setup
### Single Node (Development)
```bash
# Start FoundationDB server
foundationdb start
# Initialize database
fdbcli --exec 'configure new single ssd'
```
### Multi-Node Cluster (Production)
1. **Install FoundationDB** on all nodes
2. **Configure cluster file** (`/etc/foundationdb/fdb.cluster`)
3. **Initialize cluster**:
```bash
fdbcli --exec 'configure new double ssd'
```
### Docker Setup
Use the provided docker-compose.yml in `test/foundationdb/`:
```bash
cd test/foundationdb
make setup
```
## Performance Considerations
### Optimal Configuration
- **API Version**: Use the latest stable API version (720+)
- **Directory Structure**: Use logical directory prefixes to isolate different SeaweedFS instances
- **Transaction Size**: Keep transactions under 10MB (FDB limit)
- **Batch Operations**: Use transactions for multiple related operations
### Monitoring
Monitor FoundationDB cluster status:
```bash
fdbcli --exec 'status'
fdbcli --exec 'status details'
```
### Scaling
FoundationDB automatically handles:
- Data distribution across nodes
- Load balancing
- Automatic failover
- Storage node addition/removal
## Testing
### Unit Tests
```bash
cd weed/filer/foundationdb
go test -tags foundationdb -v
```
### Integration Tests
```bash
cd test/foundationdb
make test
```
### End-to-End Tests
```bash
cd test/foundationdb
make test-e2e
```
## Troubleshooting
### Common Issues
1. **Connection Failures**:
- Verify cluster file path
- Check FoundationDB server status
- Validate network connectivity
2. **Transaction Conflicts**:
- Reduce transaction scope
- Implement retry logic
- Check for concurrent operations
3. **Performance Issues**:
- Monitor cluster health
- Check data distribution
- Optimize directory structure
### Debug Information
Enable verbose logging:
```bash
weed -v=2 server -filer
```
Check FoundationDB status:
```bash
fdbcli --exec 'status details'
```
## Security
### Network Security
- Configure TLS for FoundationDB connections
- Use firewall rules to restrict access
- Monitor connection attempts
### Data Encryption
- Enable encryption at rest in FoundationDB
- Use encrypted connections
- Implement proper key management
## Limitations
- Maximum transaction size: 10MB
- Single transaction timeout: configurable (default 5s)
- API version compatibility required
- Requires FoundationDB cluster setup
## Support
For issues specific to the FoundationDB filer store:
1. Check FoundationDB cluster status
2. Verify configuration settings
3. Review SeaweedFS logs with verbose output
4. Test with minimal reproduction case
For FoundationDB-specific issues, consult the [FoundationDB documentation](https://apple.github.io/foundationdb/).

Package foundationdb provides a FoundationDB-based filer store for SeaweedFS.
FoundationDB is a distributed ACID database with strong consistency guarantees
and excellent scalability characteristics. This filer store leverages FDB's
directory layer for organizing file metadata and its key-value interface for
efficient storage and retrieval.
The referenced "github.com/apple/foundationdb/bindings/go/src/fdb" library
requires FoundationDB client libraries to be installed.
So this is only compiled with "go build -tags foundationdb".

//go:build foundationdb

// Package foundationdb provides a filer store implementation using FoundationDB as the backend.
//
// IMPORTANT DESIGN NOTE - DeleteFolderChildren and Transaction Limits:
//
// FoundationDB imposes strict transaction limits:
// - Maximum transaction size: 10MB
// - Maximum transaction duration: 5 seconds
//
// The DeleteFolderChildren operation always uses batched deletion with multiple small transactions
// to safely handle directories of any size. Even if called within an existing transaction context,
// it will create its own batch transactions to avoid exceeding FDB limits.
//
// This means DeleteFolderChildren is NOT atomic with respect to an outer transaction - it manages
// its own transaction boundaries for safety and reliability.
