In Elasticsearch, we execute intra-segment searches across multiple threads, which can trigger redundant, concurrent cache populations for the same segment. Since each slice-search targets a subset of the segment but cache population scans the entire segment, this amplification significantly wastes I/O and CPU for expensive queries. This PR introduces a hook in LRUQueryCache to allow custom population strategies, such as delegating to a background thread or skipping redundant populations. There is no change to the default behavior of LRUQueryCache. -- This is an automated message from the Apache Git Service.
