pre-release v9.18.0-beta.1

🚀 Highlights

Request and Response Policy Based Routing in Cluster Mode

This beta release introduces comprehensive support for Redis COMMAND-based request and response policy routing for cluster clients. This feature enables intelligent command routing and response aggregation based on Redis command metadata.

Key Features:

• Command Policy Loader: Automatically parses and caches COMMAND metadata with routing/aggregation hints
• Enhanced Routing Engine: Supports all request policies including:
  • default(keyless) - Commands without keys
  • default(hashslot) - Commands with hash slot routing
  • all_shards - Commands that need to run on all shards
  • all_nodes - Commands that need to run on all nodes
  • multi_shard - Commands that span multiple shards
  • special - Commands with custom routing logic
• Response Aggregator: Intelligently combines multi-shard replies based on response policies:
  • all_succeeded - All shards must succeed
  • one_succeeded - At least one shard must succeed
  • agg_sum - Aggregate numeric responses
  • special - Custom aggregation logic (e.g., FT.CURSOR)
• Raw Command Support: Policies are enforced on Client.Do(ctx, args...)

This feature is particularly useful for Redis Stack commands like RediSearch that need to operate across multiple shards in a cluster.

Connection Pool Improvements

Fixed a critical defect in the connection pool's turn management mechanism that could lead to connection leaks under certain conditions. The fix ensures proper 1:1 correspondence between turns and connections.
