## JVM configuration
################################################################
## importANT: JVM heap size
################################################################
##
## You should always set the min and max JVM heap
## size to the same value. For example, to set
## the heap to 4 GB, set:
##
## -Xms4g
## -Xmx4g
##
## See https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html
## for more information
##
################################################################# Xms represents the initial size of total heap space
# Xmx represents the maximum size of total heap space-Xms1g
-Xmx1g################################################################
