Module pool 

Connection pool for SQLite.

This module provides an optimized connection pool for SQLite databases. Unlike PostgreSQL/MySQL, SQLite has unique characteristics:

• In-memory databases: Each connection has its own isolated database
• File-based databases: Connections share the same database file

In-memory caveat: because every in-memory connection is its own isolated database, an in-memory pool isolates every statement on its own database. Use transaction() to pin a single connection, or a tempfile/shared-cache URI, for multi-statement workflows.

For file-based databases, this pool reuses connections to avoid the overhead of opening new connections (~200µs per open).
