9"""Connection pooling for DB-API connections. 

10 

11Provides a number of connection pool implementations for a variety of 

12usage scenarios and thread behavior requirements imposed by the 

13application, DB-API or database itself.

15Also provides a DB-API 2.0 connection proxying mechanism allowing 

16regular DB-API connect() methods to be transparently managed by a 

17SQLAlchemy connection pool.
