################################################################ ## IMPORTANT: JVM heap size ################################################################ ## ## The heap size is automatically configured by Elasticsearch ## based on the available memory in your system and the roles ## each node is configured to fulfill. If specifying heap is ## required, it should be done through a file in jvm.options.d, ## and the min and max should be set to the same value. For ## example, to set the heap to 4 GB, create a new file in the ## jvm.options.d directory containing these lines: ## ## -Xms4g ## -Xmx4g ## ## See https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html ## for more information ## ################################################################
