Other Supported Resources

bootstrap.mlockall

The service enables bootstrap.mlockall 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

Scripting module

The service supports scripting for Elasticsearch 5.x and newer domains. The service 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 newer domains, Amazon ES supports stored scripts using the _scripts endpoint. Elasticsearch 5.3 and 5.1 domains only support inline scripts.

TCP transport

The service supports HTTP on port 80, but does not support TCP transport.
