Other supported resources in Amazon Elasticsearch Service

This topic describes additional resources that Amazon Elasticsearch Service (Amazon ES) supports.

bootstrap.memory_lock

Amazon ES enables bootstrap.memory_lock in elasticsearch.yml, which locks JVM memory and prevents the operating system from swapping it to disk. This applies to all supported instance types except for the following:

  • t2.micro.elasticsearch

  • t2.small.elasticsearch

  • t2.medium.elasticsearch

  • t3.small.elasticsearch

  • t3.medium.elasticsearch

Scripting module

Amazon ES supports scripting for Elasticsearch 5.x and later domains. It does not support scripting for 1.5 or 2.3.

Supported scripting options include the following:

  • Painless

  • Lucene Expressions

  • Mustache

For Elasticsearch 5.5 and later domains, Amazon ES supports stored scripts using the _scripts endpoint. Elasticsearch 5.3 and 5.1 domains support inline scripts only.

TCP transport

Amazon ES supports HTTP on port 80 and HTTPS over port 443, but does not support TCP transport.
