ElasticSearch Service have a useful metric JVM memory pressure that specifies the percentage of the Java heap occupied in a cluster node. CMSInitiatingOccupancyFraction is the threshold value on which Garbage collection activity starts to clean deleted items from ES node memory to reduce JVM Memory pressure. refer article for more information
Our application have clean up tasks executed on weekly basis and we are exploring options to lower down CMSInitiatingOccupancyFraction (which is by default set to 75%) value. As cleanup tasks gets executed we are thinking of setting this threshold to 65-70%. We didn't found any configuration options to fix this value. Is there any other mechanism to activate Garbage collector?
Does AWS Elastic search service provide options to configure these default values? If yes then guide us through steps.
