Best practices: Pub/Sub and Enhanced I/O Multiplexing

When using Valkey or Redis OSS version 7 or later, we recommend using sharded Pub/Sub. You also improve throughput and latency using enhanced I/O multiplexing, which is automatically available when using Valkey or Redis OSS version 7 or later and requires no client changes. It is ideal for pub/sub workloads, which often are throughput-bound with multiple client connections.
