11. Database Access Pattern

sequenceDiagram
    participant Bot as Bot System
    participant Cache as Cache Layer
    participant Pool as Connection Pool
    participant DB as Database

    Bot->>Cache: Request Data

    alt Cache Hit
        Cache-->>Bot: Return Cached Data
    else Cache Miss
        Cache->>Pool: Get Connection
        Pool->>Pool: Check Available

        alt Connection Available
            Pool-->>Cache: Connection
        else Create New
            Pool->>DB: Create Connection
            DB-->>Pool: New Connection
            Pool-->>Cache: Connection
        end

        Cache->>DB: Execute Query
        DB-->>Cache: Query Result

        Cache->>Cache: Update Cache
        Cache->>Pool: Return Connection
        Pool->>Pool: Add to Pool

        Cache-->>Bot: Return Data
    end

    Note over Cache: Async write-back every 30s

    loop Write-back
        Cache->>Pool: Get Connection
        Pool-->>Cache: Connection
        Cache->>DB: Batch Update
        DB-->>Cache: Success
        Cache->>Pool: Return Connection
    end
