OpenSearch Lucene Study Group - May 23rd, 2024

In this meeting we covered exciting prefetch changes coming in Lucene 10.0 that should help OpenSearch’s remote store performance, improved performance of dot-products when using compressed int4 vectors, the state of JDK21 in Lucene and OpenSearch, and improved concurrency on Lucene’s query cache. The meeting ended with a preview discussion for next week’s topic: Lucene’s facets implementation and OpenSearch’s aggregations.
