psycopg is a PostgreSQL database adapter for the Python programming
|
|
language. It was written from scratch with the aim of being very small and
|
|
fast, and stable as a rock. The main advantages of psycopg are that it
|
|
supports the full Python DBAPI-2.0 and being thread safe at level 2.
|
|
|
|
psycopg is different from the other database adapter because it was designed
|
|
for heavily multi-threaded applications that create and destroy lots of
|
|
cursors and make a conspicuous number of concurrent INSERTs or UPDATEs.
|
|
Every open Python connection keeps a pool of real (UNIX or TCP/IP)
|
|
connections to the database. Every time a new cursor is created, a new
|
|
connection does not need to be opened; instead one of the unused connections
|
|
from the pool is used. That makes psycopg very fast in typical client-server
|
|
applications that create a servicing thread every time a client request
|
|
arrives.
