# This file lists dependencies that are used by different pluggable (optional)
# parts of TaskFlow, like engines or persistence backends. They are not
# strictly required by TaskFlow (aka you can use TaskFlow without them), so
# they don't go into one of the requirements.txt files.
# The order of packages is significant, because pip processes them in the order
# of appearance. Changing the order has an impact on the overall integration
# process, which may cause wedges in the gate later.
# Database (sqlalchemy) persistence:
SQLAlchemy>=0.7.8,<=0.9.99
alembic>=0.4.1
# Database (sqlalchemy) persistence with MySQL:
MySQL-python
# NOTE(imelnikov): pyMySQL should be here, but for now it's commented out
# because of https://bugs.launchpad.net/openstack-ci/+bug/1280008
# pyMySQL
# Database (sqlalchemy) persistence with PostgreSQL:
psycopg2
# ZooKeeper backends
kazoo>=1.3.1
# Eventlet may be used with parallel engine:

# Needed for the worker-based engine:
