    ## WARNING: DO NOT EDIT THIS FILE. If you want to override the
    ## JVM options in this file, or set any additional options, you
    ## should create one or more files in the jvm.options.d

    ## 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
