Summary

Elasticsearch 6.0.0-alpha1, a pre-release version based on Lucene 7-SNAPSHOT, introduces several changes and features aimed at simplifying the upgrade process from previous versions and enhancing performance. This alpha release is intended for testing purposes only and is not compatible with the final 6.0.0 version, nor should it be used in production environments. Notable improvements include support for sparse doc values, index sorting for faster search results, and sequence numbers for more efficient shard recovery. The upgrade process is streamlined through rolling restarts and cross-cluster search capabilities, negating the need for full cluster restarts and reindexing of older indices. Elasticsearch 6.0.0 will also phase out mapping types, allowing only one type per index, which simplifies the structure and enhances API interactions. Users are encouraged to test this alpha version, report issues, and provide feedback to contribute to its development.
