PG MUTEX

Python wrapper around Postgres pg_advisory_lock and pg_try_advisory_lock functions. It is possible, thanks to a common connection to the database, to block certain pieces of python code by different python processes, on different nodes.

Installation

pip install pg-mutex

Usage

from mutex import mutex

with mutex(connection, ['param1', 'param2']):
    # here is code that is guaranteed to be executed by only one process, even on different nodes
    pass
