Routing and connection management for Redis in Python

rb

rb - the redis blaster.

The fastest way to talk to many redis nodes. Can do routing as well as blindly blasting commands to many nodes. How does it work?

For full documentation see rb.rtfd.org

Quickstart

Set up a cluster:

from rb import Cluster

cluster = Cluster({
    0: {'port': 6379},
    1: {'port': 6380},
    2: {'port': 6381},
    3: {'port': 6382},
}, host_defaults={
    'host': '127.0.0.1',
})

Automatic routing:

results = []
with cluster.map() as client:
    for key in range(100):
        client.get(key).then(lambda x: results.append(int(x or 0)))

print('Sum: %s' % sum(results))

Fanout:

with cluster.fanout(hosts=[0, 1, 2, 3]) as client:
    infos = client.info()

Fanout to all:

with cluster.fanout(hosts='all') as client:
    client.flushdb()
