Mapper Plugins

Mapper plugins allow new field datatypes to be added to Elasticsearch.

Core mapper plugins

The core mapper plugins are:

[mapper-size]

The mapper-size plugin provides the _size meta field which, when enabled, indexes the size in bytes of the original {ref}/mapping-source-field.html[_source] field.

[mapper-murmur3]

The mapper-murmur3 plugin allows hashes to be computed at index-time and stored in the index for later use with the cardinality aggregation.
