I am executing one query, for first time it is taking 6 7 sec. After running second time it took only 1 sec.

I check clear cache options on OpenSearch documentation. But I can not see any query performance as it is taking only 1 sec.

I tried to clear cache and checked stats of cluster but it is showing like "memory_size_in_bytes":0 before clearing cache and even after clearing cache.

What I can do if I want to clear cache and run same query again and again?

  • can you share `GET /_nodes/stats/indices/request_cache?human&pretty&filter_path=**.*cache*` https://www.elastic.co/guide/en/elasticsearch/reference/current/shard-request-cache.html – Musab Dogan Jul 11 '23 at 14:54
