1psycopg2 is a PostgreSQL database adapter for the Python programming language. 2It was written from scratch with the aim of being small, fast and stable. It 3supports the full Python DBAPI-2.0 and is thread safe. 4 5psycopg2 is different from the other database adapter because it was designed 6for heavily multi-threaded applications that create and destroy lots of cursors 7and make a conspicuous number of concurrent INSERTs or UPDATEs. Every open 8Python connection keeps a pool of real (UNIX or TCP/IP) connections to the 9database. Every time a new cursor is created, a new connection does not need to 10be opened; instead one of the unused connections from the pool is used. That 11makes psycopg very fast in typical client-server applications that create a 12servicing thread every time a client request arrives. 13 14WWW: http://initd.org/psycopg/ 15WWW: https://github.com/psycopg/psycopg2 16
