Hi!  
Is there any possibility to set an upper bound for the RAM usage of Elasticsearch?

Thanks!

Hello,

the usual way is configuring the -Xmx Parameter for the Java-VM. By setting this parameter in (usually) the jvm.options file You limit the maximum amount of the JVM heap, in which Elasticsearch runs.

See [Elasticsearch Documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/jvm-options.html).

Regards,
