asgi_redis 0.8.3

Redis-backed ASGI channel layer implementation

An ASGI channel layer that uses Redis as its backing store, and supports both a single-server and sharded configurations, as well as group support.

Usage

You’ll need to instantiate the channel layer with connection details, which include:

• hosts: The server(s) to connect to, as either URIs or (host, port) tuples. Defaults to ['localhost', 6379]. Pass multiple hosts to enable sharding, but note that changing host list will lose most sharded data.

• prefix: Prefix to add to all Redis keys. Defaults to asgi:.

• expiry: Message expiry in seconds. Defaults to 60.

Example:

channel_layer = RedisChannelLayer(
    host="redis",
    db=4,
)

TODO

• Expire/clean out groups

• Prune channel lists on write/periodically as well as on read

• Efficient send_group implementation with Lua
