- Columnar index modes available as a technical preview. #290
Two new index modes,
columnarandlogsdb_columnar, are now available as a Tech Preview. With columnar mode enabled, Elasticsearch becomes a fully columnar store for search and analytics, offering a significantly smaller storage footprint and the building blocks for faster analytical queries in future releases.
- Enable the batched query phase. #148622
Searches that target multiple shards on the same data node now batch shards into a single round-trip per data node, with partial reductions performed on the data nodes.
This reduces transport layer overhead and spreads the load of reductions across multiple nodes.
The enhancement is controlled by a setting
search.batched_query_phase, which is enabled by default in 9.5.0.
