New in version 2.3.

The maximum number of connections that can be open in the connection pool.

The pool is enabled by default since version 2.5, with a default limit of ten connections. This number can be tweaked depending on the number of threads/greenthreads (eventlet/gevent) using a connection. For example running eventlet with 1000 greenlets that use a connection to the broker, contention can arise and you should consider increasing the limit.

If set to None or 0 the connection pool will be disabled and connections will be established and closed for every use.

Default (since 2.5) is to use a pool of 10 connections. CELERY_REDIS_MAX_CONNECTIONSMaximum number of connections available in the Redis connection pool used for sending and retrieving results.  BROKER_TRANSPORT_OPTIONS

New in version 2.2.

A dict of additional options passed to the underlying transport.

See your transport user manual for supported options (if any).

Example setting the visibility timeout (supported by Redis and SQS transports):

BROKER_TRANSPORT_OPTIONS = {‘visibility_timeout‘: 18000}  # 5 hours
