pgnotify is a PostgreSQL client-side asynchronous notification handler for
|
|
Python and PyGreSQL.
|
|
|
|
Typically, asynchronous notification is used to communicate the message "I
|
|
changed this table, take a look at it to see what's new" from one PostgreSQL
|
|
client to other interested PostgreSQL clients.
|
|
|
|
A useful programming technique is to generate asynchronous notification in a
|
|
rule that is triggered by table updates; this way, notification happens
|
|
automatically when the table is changed and the application programmer can't
|
|
accidentally forget to do it.
|
|
|
|
At present, pgnotify works with PyGreSQL only. It should work with PoPy and
|
|
psycopg when those modules provide Pythonic interfaces to additional necessary
|
|
PostgreSQL client-side functions, as described in the README.
