Hi I have a solr-cloud cluster with a big collection, after startup (no any search/index operations), its jvm memory usage is 9GB (via top: RES).
Cluster and collection info: each host: total 64G mem, two solr nodes with -xmx=15G collection: total 9B billion docs (but each doc is very small: only some bytes), total size 3TB. My question is: Is the 9G mem usage after startup normal? If so, I am worried that the follow up index/search operations will cause an OOM error. And how can I reduce the memory usage? Maybe I should introduce more host with nodes, but besides this, is there any other solution? Thanks.
