Mapper Murmur3 Plugin

The mapper-murmur3 plugin provides the ability to compute hash of field values at index-time and store them in the index. This can sometimes be helpful when running cardinality aggregations on high-cardinality and large string fields.

This plugin can be installed using the plugin manager:

sudo bin/elasticsearch-plugin install mapper-murmur3

The plugin must be installed on every node in the cluster, and each node must be restarted after installation.

This plugin can be downloaded for offline install from https://artifacts.elastic.co/downloads/elasticsearch-plugins/mapper-murmur3/mapper-murmur3-7.5.2.zip.

The plugin can be removed with the following command:

sudo bin/elasticsearch-plugin remove mapper-murmur3

The node must be stopped before removing the plugin.
