Mapper murmur3 pluginedit

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 download this plugin for offline install from To verify the .zip file, use the SHA hash or ASC key.


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.
