"""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.
