## 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,
|
|
## which should be named with .options suffix, 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/8.8/heap-size.html
