Elasticsearch versions 8.6, 8.7, and 8.8 have introduced significant optimizations that enhance data ingestion speeds across various data sets, including keyword, numeric, and k-nearest neighbors (kNN) vectors as well as ingest-pipeline-heavy workloads. Improvements were made in multiple areas: faster merging of kNN vectors through better reuse of existing graph structures, optimized ingest pipelines with reduced overhead and enhanced processor efficiency, and advancements in indexing keyword and numeric fields with the adoption of new Lucene field types. Additionally, index sorting was improved to accelerate queries, and a new merge policy for time-based data maintained non-overlapping segment properties, which is beneficial for range queries on timestamps. These enhancements resulted in notable performance gains, such as a 13% faster ingestion rate from version 8.6 to 8.8 and increased throughput in various benchmarks, ultimately reducing the load on systems handling sizable vector data sets.
