Performance Issues of Redis Cluster MGET and Optimization Strategies

In a Redis cluster, bulk MGET calls suffered intermittent latency spikes because keys were distributed across many hash slots, forcing multiple network round‑trips; the issue can be mitigated by grouping keys with a common hash tag (though it reduces HA) or by issuing parallel slot‑wise MGETs with careful tuning, which preserves topology for larger batches.

Why Merging Redis Requests Can Still Slow Your System – A Real‑World Debugging Tale

The author recounts a real‑world incident where consolidating many Redis GET calls into a single MGET reduced network latency but unexpectedly increased overall response time, leading to timeout errors; they detail the investigation using Redis slowlog, code analysis, and proper pagination techniques to resolve the hidden performance bottleneck.
