### Database Configuration
AISBF supports multiple database backends for persistent storage of configurations, token usage tracking, and context management:
#### Supported Databases
- **SQLite** (Default): File-based database, no additional setup required, suitable for most users
- **MySQL**: Network database server, better for multi-server deployments and advanced analytics
#### SQLite Configuration (Default)
SQLite is automatically configured and requires no additional setup:
- Database file: `~/.aisbf/aisbf.db`
- Automatic initialization and table creation
- WAL mode enabled for concurrent access
- Automatic cleanup of old records
#### MySQL Configuration
For production deployments requiring MySQL:
**Prerequisites:**
- MySQL server installed and running
- Database and user created with appropriate permissions
**Via Dashboard:**
1. Navigate to Dashboard → Settings → Database Configuration
2. Select "MySQL" as database type
3. Configure connection parameters:
- **Host**: MySQL server hostname/IP
- **Port**: MySQL server port (default: 3306)
- **Username**: MySQL database username
- **Password**: MySQL database password
- **Database**: MySQL database name
4. Save settings and restart server
**Via Configuration File:**
Edit `~/.aisbf/aisbf.json`:
```json
{
"database": {
"type": "mysql",
"mysql_host": "localhost",
"mysql_port": 3306,
"mysql_user": "aisbf",
"mysql_password": "your_password",
"mysql_database": "aisbf"
}
}
```
**Database Migration:**
When switching database types, AISBF will automatically create tables in the new database. Existing data will not be migrated automatically - you may need to export/import configurations manually.
### Cache Configuration
AISBF includes a flexible caching system for improved performance and reduced API costs:
#### Supported Cache Backends
- **SQLite** (Default): Local database storage, persistent and structured
- **MySQL**: Network database caching, scalable for multi-server deployments
- **Redis**: High-performance distributed caching, recommended for production
- **File-based**: Legacy local file storage
- **Memory**: In-memory caching (ephemeral, lost on restart)
#### Cache Features
- **Model Embeddings**: Cached vectorized model descriptions for semantic matching
- **Provider Models**: Cached API model listings with configurable TTL
- **Automatic Fallback**: Falls back to file-based if Redis is unavailable
- **Configurable TTL**: Set cache expiration times per data type
#### Redis Configuration
For high-performance caching in production environments:
**Prerequisites:**
- Redis server installed and running
- Optional: Redis authentication configured
**Via Dashboard:**
1. Navigate to Dashboard → Settings → Cache Configuration
2. Select "Redis" as cache type
3. Configure connection parameters:
- **Host**: Redis server hostname/IP
- **Port**: Redis server port (default: 6379)
- **Database**: Redis database number (default: 0)
- **Password**: Redis password (optional)
- **Key Prefix**: Prefix for Redis keys (default: aisbf:)
4. Save settings and restart server
**Via Configuration File:**
Edit `~/.aisbf/aisbf.json`:
```json
{
"cache": {
"type": "redis",
"redis_host": "localhost",
"redis_port": 6379,
"redis_db": 0,
"redis_password": "",
"redis_key_prefix": "aisbf:"
}
}
```
#### Cache Performance Benefits
- **Faster Model Selection**: Cached embeddings eliminate repeated vectorization
- **Reduced API Calls**: Cached provider model listings reduce API overhead
- **Lower Latency**: Redis provides sub-millisecond cache access
- **Scalability**: Distributed Redis supports multiple AISBF instances
### Provider-Level Defaults
Providers can now define default settings that cascade to all models:

## 🔥 HIGH PRIORITY (Implement Soon)
### 1. Integrate Existing Database Module
**Estimated Effort**: 4-6 hours
**Expected Benefit**: Persistent rate limiting, analytics foundation, multi-user support
**ROI**: ⭐⭐⭐⭐⭐ Very High (Quick Win!)
**Status**: ✅ **COMPLETED** - Database fully integrated with multi-user authentication and role-based access control!
#### Background
AISBF now has a fully functional SQLite database at `~/.aisbf/aisbf.db` that tracks:
- **Context dimensions** per model (context_size, condense_context, effective_context)
- **Token usage** for rate limiting (TPM/TPH/TPD tracking) with persistence across restarts
- **Model embeddings** caching for semantic classification performance
- **Multi-user support** with isolated configurations and authentication
#### Tasks:
- [x] Initialize database on startup
- [x] Add `initialize_database()` call in `main.py` startup
- [x] Test database creation and WAL mode
- [x] Add error handling for database initialization
- [x] Integrate token usage tracking
- [x] Modify `BaseProviderHandler._record_token_usage()` in `aisbf/providers.py:300`
- [x] Add database call: `get_database().record_token_usage(provider_id, model, tokens)`
- [x] Keep in-memory tracking for immediate rate limit checks
- [x] Use database for persistent tracking across restarts
- [x] Integrate context dimension tracking
- [x] Add database call in `ContextManager` to record context config
- [x] Add database call to update effective_context after requests
- [x] Use for analytics and optimization recommendations
- [x] Add database cleanup
- [x] Schedule periodic cleanup of old token_usage records (>7 days)
- [x] Add cleanup on startup
- [x] Add manual cleanup endpoint in dashboard
- [x] Dashboard integration (optional, can be done later)
- [x] Add multi-user authentication with role-based access control
- [x] Admin users can manage users, regular users have restricted access
- [x] User-specific configuration tables (providers, rotations, autoselects, API tokens)
- [x] Database-first authentication with config admin fallback
**Files to modify**:
- `main.py` (add initialize_database() call)
- `aisbf/providers.py` (BaseProviderHandler._record_token_usage)
- `aisbf/context.py` (ContextManager)
- `aisbf/handlers.py` (optional: add context tracking)
**Benefits**:
- ✅ Persistent rate limiting across restarts
- ✅ Foundation for analytics dashboard (item #6)
- ✅ Historical token usage tracking
- ✅ Better cost visibility
- ✅ No new dependencies needed (SQLite is built-in)
**Why First?**:
- Quick win (4-6 hours vs days for other items)
- Enables better tracking for all other improvements
- Foundation for analytics and optimization
- Already implemented, just needs wiring
