2.9.24

IMPORTANT: this release changes the distribution of pub/sub channels when using cluster:

(this change is specific to pub/sub with regular SUBSCRIBE channels, not "sharded" SSUBSCRIBE channels)

• pre 2.9.24: all channels would always be routed similarly to key-like routing (and similar to SSUBSCRIBE)
• from 2.9.24: non-SSUBSCRIBE channels are now randomly distributed to nodes by default, but can optionally use key-like routing by calling .WithKeyRouting() on the RedisChannel value

This change represents a safer, "least surprises" default; most people expect their cluster to help distribute load, including pub/sub load, between nodes. This is especially useful when there are few (or even only a single) channel(s) that dominate the pub/sub load, which is surprisingly common. Without this change, all that load would be handled only by a single server, because the channel my_notifications would be treated similarly to a key, via hash-slot sharding, and all clients would connect to the node serving that slot - when in reality, any node can be used for subscription, with the server distributing events horizontally to all nodes.

If you prefer the routed behaviour: use .WithKeyRouting() before subscribing.

2.8.41

What's Changed

• Support sharded pubsub commands by @mgravell @vandyvilla @atakavci @xli in #2887

Sharded pub/sub operations are where the pub/sub channels are distributed over a multi-node redis cluster using similar slot rules to keys; all such operations (for both "pub" and "sub") must be communicated to the correct node. This contrasts to regular/legacy pub/sub where you can "pub" or "sub" to any node, and the message is broadcast horizontally via all nodes in the cluster. To use sharded operations, use the RedisChannel.Sharded API when constructing channels. There is no concept of pattern-based sharded pub/sub.
