What’s new in 8.1

edit

Here are the highlights of what’s new and improved in Elasticsearch 8.1!

Other versions:

8.0

Doc-values-only search on numeric, date, keyword, ip, and boolean fields

edit

You can now run term and range queries on numeric, date, date_nanos, keyword, ip, and boolean fields that only store doc values.

In exchange for slower queries, doc-value-only fields offer:

  • Increased indexing rates
  • Better storage efficiency
  • Great performance for aggregating and sorting data

For more information about doc values, refer to the doc_values mapping parameter documentation.
