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.

You can also download this plugin for offline install. Download the build that matches the Elasticsearch version you are running.

Download the build for 9.5.5:

https://artifacts.elastic.co/downloads/elasticsearch-plugins/mapper-murmur3/mapper-murmur3-9.5.5.zip

To verify the .zip file, use the SHA hash or ASC key.

Replace <SPECIFIC.VERSION.NUMBER> with the Elasticsearch version you are running. For example, you can replace <SPECIFIC.VERSION.NUMBER> with 9.0.0.
