Hi All, We observe the relatively high heap usage : 70-75% per node. Our heap size is 32G. Each node has 2 shards (one primary , one replica). Each shard size is approximately 43G The size of the field data cache is ~22G and there are zero evictions from this cache The size of the filter cache is ~28G and there are many evictions Is it normal having such large cache sizes? We think it affects our queries performance. On an empty cache a query latency is 2-3 minutes for the first run. Second run takes 10 seconds (and after some time again 2 min) Does it those 2-3 min take to Elastic to rebuild/refresh the caches? Why it's so long? Please help us to understand how Elastic creates filter cache and field data cache. When does Elastic create these caches and how does it affect the queries performance?
