- """Connection pooling for DB-API connections.
-
- Provides a number of connection pool implementations for a variety of
- usage scenarios and thread behavior requirements imposed by the
- application, DB-API or database itself.
-
- Also provides a DB-API 2.0 connection proxying mechanism allowing
- regular DB-API connect() methods to be transparently managed by a
- SQLAlchemy connection pool.
