Elastic Releases Major Updates for Enterprise Search, Observability, and Security, Powered By The Elastic Stack

We are pleased to announce the release of Elasticsearch 7.7.0, based on Lucene 8.5.1. Version 7.7 is the latest stable release of Elasticsearch, and is now available for download or deployment via Elasticsearch Service on Elastic Cloud.

Asynchronous search

With the release of Elasticsearch 7.7, asynchronous search makes long-running queries feasible and reliable. Async search allows users to run long-running queries in the background, track the query progress, and retrieve partial results as they become available. Async search enables users to more easily search vast amounts of data with no more pesky timeouts.

Reduced consumption of heap

Cluster administrators know that excessive heap consumption can cause a number of administrative challenges. Having high heap pressure in an application like Elasticsearch can lead to search and indexing performance degradation or worse: OutOfMemory errors.

With the release of Elasticsearch 7.7 we’ve dramatically reduced heap memory consumption for these time-series use cases by moving the terms index of the _id off heap. While having the terms index of _id on-heap was useful when indexing with explicit IDs, we studied how our community of users and customers were using Elasticsearch and realized that making this small change will help most cluster admins to maintain more economical clusters or to scale their existing clusters to hold more documents.
