Issue fixed in this release:

  • Performance: Long-term index caching in the global cache, as introduced in 4.6, hurts the performance for workloads where accesses to the index are sparse. To mitigate this, a new configuration parameter cache_index_pages (default true) is introduced to control index caching. Setting the flag to `false` causes all index reads to behave like they would in BYPASS CACHE queries. Consider using false if you notice performance problems due to lowered cache hit ratio in 4.6 or 5.0. The config API can update the parameter live (without restart). #11202
