//! Coverage Areas:
|
|
//! - PostgreSQL trade and order persistence
|
|
//! - InfluxDB time-series market data storage
|
|
//! - Redis caching and session management
|
|
//! - ClickHouse analytics queries
|
|
//! - Database connection pooling
|
|
//! - Transaction consistency and rollback
|
|
//! - Backup and recovery procedures
|
