# Database Quick Start Guide **Foxhunt HFT Trading System - Audit Infrastructure** --- ## Connection Information ```bash Host: localhost Port: 5433 Database: foxhunt_test User: foxhunt_test Password: test_password ``` ### Environment Variable ```bash export DATABASE_URL=postgresql://foxhunt_test:test_password@localhost:5433/foxhunt_test ``` ### Rust Connection (sqlx) ```rust use sqlx::postgres::PgPool; let pool = PgPool::connect("postgresql://foxhunt_test:test_password@localhost:5433/foxhunt_test") .await?; ``` --- ## Quick Tests ### 1. Test Connectivity ```bash PGPASSWORD=test_password psql -h localhost -p 5433 -U foxhunt_test -d foxhunt_test -c "SELECT version();" ``` ### 2. Count Audit Tables ```bash PGPASSWORD=test_password psql -h localhost -p 5433 -U foxhunt_test -d foxhunt_test -c " SELECT COUNT(*) FROM information_schema.tables WHERE table_name LIKE '%audit%' AND table_schema = 'public';" ``` ### 3. Insert Test Event ```bash PGPASSWORD=test_password psql -h localhost -p 5433 -U foxhunt_test -d foxhunt_test -c " INSERT INTO security_audit_log (event_type, success, error_message) VALUES ('admin_action', true, 'Test event') RETURNING id;" ``` --- ## Available Audit Tables (8 tables) | Table | Purpose | Size | Indexes | |-------|---------|------|---------| | `security_audit_log` | Security events | 120 kB | 6 | | `sox_trade_audit` | SOX compliance | 48 kB | 5 | | `transaction_audit_events` | HFT transactions | 152 kB | 12 | | `kill_switch_audit` | Circuit breaker | 40 kB | 4 | | `position_limits_audit` | Position monitoring | 40 kB | 4 | | `mifid_transaction_report` | MiFID II reporting | 40 kB | 4 | | `best_execution_analysis` | Execution quality | 40 kB | 4 | | `compliance_rule_executions` | Rule tracking | 40 kB | 4 | --- ## Common Operations ### Log Security Event ```sql INSERT INTO security_audit_log (event_type, success, error_message, ip_address) VALUES ('login_attempt', true, NULL, '192.168.1.1') RETURNING id; ``` ### Log Trade (SOX) ```sql SELECT log_sox_trade_activity( 'f47ac10b-58cc-4372-a567-0e02b2c3d479'::uuid, -- trade_id 'a0eebc99-9c0b-4ef8-bb6d-6bb9bd380a11'::uuid, -- user_id 'AAPL', -- symbol 'BUY', -- side 100.0, -- quantity 150.25, -- price 'LIMIT', -- order_type 15025.00, -- trade_value NOW(), -- order_timestamp NULL, -- risk_assessment NULL -- compliance_flags ); ``` ### Query Recent Events ```sql SELECT event_type, success, created_at FROM security_audit_log ORDER BY created_at DESC LIMIT 10; ``` ### Activate Kill Switch ```sql SELECT activate_kill_switch( 'AUTOMATIC', 'Risk limit exceeded', 'HIGH', 'a0eebc99-9c0b-4ef8-bb6d-6bb9bd380a11'::uuid, 1000000.00, -50000.00 ); ``` --- ## Rust Code Examples ### Insert Audit Event ```rust use sqlx::PgPool; use uuid::Uuid; async fn log_security_event( pool: &PgPool, event_type: &str, success: bool, error_msg: Option<&str>, ) -> Result { let record = sqlx::query!( r#" INSERT INTO security_audit_log (event_type, success, error_message) VALUES ($1, $2, $3) RETURNING id "#, event_type, success, error_msg ) .fetch_one(pool) .await?; Ok(record.id) } ``` ### Query Audit Events ```rust use sqlx::PgPool; use chrono::{DateTime, Utc}; #[derive(Debug)] struct AuditEvent { id: Uuid, event_type: String, success: bool, created_at: DateTime, } async fn get_recent_events( pool: &PgPool, limit: i64, ) -> Result, sqlx::Error> { let events = sqlx::query_as!( AuditEvent, r#" SELECT id, event_type, success, created_at FROM security_audit_log ORDER BY created_at DESC LIMIT $1 "#, limit ) .fetch_all(pool) .await?; Ok(events) } ``` ### Call Audit Function ```rust use sqlx::PgPool; use uuid::Uuid; async fn log_sox_trade( pool: &PgPool, trade_id: Uuid, user_id: Uuid, symbol: &str, side: &str, quantity: f64, price: f64, ) -> Result { let record = sqlx::query!( r#" SELECT log_sox_trade_activity( $1::uuid, $2::uuid, $3, $4, $5, $6, 'LIMIT', $7, NOW(), NULL, NULL ) as audit_id "#, trade_id, user_id, symbol, side, quantity, price, quantity * price ) .fetch_one(pool) .await?; Ok(record.audit_id.unwrap()) } ``` --- ## Available Functions | Function | Purpose | Returns | |----------|---------|---------| | `log_sox_trade_activity(...)` | Log SOX trade | UUID | | `log_security_event(...)` | Log security event | UUID | | `activate_kill_switch(...)` | Activate circuit breaker | UUID | | `check_position_limits(...)` | Check position limits | UUID | | `verify_audit_event_integrity(event_id)` | Verify checksum | BOOLEAN | | `query_audit_events(...)` | Query with filters | TABLE | | `get_audit_event_statistics(...)` | Get statistics | TABLE | --- ## Regulatory Compliance ### SOX (Sarbanes-Oxley) - **Table**: `sox_trade_audit` - **Requirements**: Section 404 (Internal Controls), Section 302 (Certification) - **Retention**: 7 years minimum - **Features**: Immutable, SHA-256 checksums, audit trail versioning ### MiFID II - **Tables**: `mifid_transaction_report`, `best_execution_analysis`, `position_limits_audit` - **Requirements**: Articles 26, 27, 57 - **Features**: RTS 22 compliance, best execution grading (A+ to F) --- ## Performance Tips 1. **Use Prepared Statements**: Prevent SQL injection and improve performance 2. **Batch Inserts**: Use transactions for multiple audit events 3. **Index Usage**: All audit tables have optimized indexes 4. **Partitioning**: Consider partitioning `transaction_audit_events` for large datasets 5. **VACUUM**: Run `VACUUM ANALYZE` regularly on audit tables --- ## Troubleshooting ### Connection Failed ```bash # Check container status docker ps | grep postgres # Check logs docker logs api_gateway_test_postgres # Restart container docker restart api_gateway_test_postgres ``` ### Slow Queries ```sql -- Check index usage SELECT schemaname, tablename, indexname, idx_scan FROM pg_stat_user_indexes WHERE schemaname = 'public' AND tablename LIKE '%audit%' ORDER BY idx_scan DESC; -- Check table statistics SELECT schemaname, relname, n_live_tup, n_dead_tup FROM pg_stat_user_tables WHERE schemaname = 'public' AND relname LIKE '%audit%'; ``` ### Disk Space Issues ```sql -- Check table sizes SELECT tablename, pg_size_pretty(pg_total_relation_size('public.'||tablename)) FROM pg_tables WHERE schemaname = 'public' AND tablename LIKE '%audit%' ORDER BY pg_total_relation_size('public.'||tablename) DESC;
