# Description Elasticsearch keyword field uses SortedSet DocValues. In our applications, “keyword” is the most frequently used field type. LUCENE-7081 has done prefix-compression for docvalues terms dict. We can do better by adding LZ4 compression to current prefix-compression. In one of our application, the dvd files were ~41% smaller with this change(from 1.95 GB to 1.15 GB). This feature is only for the high-cardinality fields. # Tests See Jira LUCENE-9663 for details. # Checklist Please review the following and check all that apply: - [x] I have reviewed the guidelines for [How to Contribute](https://wiki.apache.org/solr/HowToContribute) and my code conforms to the standards described there to the best of my ability. - [x] I have created a Jira issue and added the issue ID to my pull request title. - [x] I have given Solr maintainers [access](https://help.github.com/en/articles/allowing-changes-to-a-pull-request-branch-created-from-a-fork) to contribute to my PR branch.
