msokolov opened a new pull request #2108: URL: https://github.com/apache/lucene-solr/pull/2108
The subject line is the main thrust, but there are a few subsidiary changes that were needed in order to achieve that (see below), and I made a few incidental improvements to HNSW-related classes. 1. Add a primitive int-valued heap, IntHeap, based on the existing PriorityQueue 2. Convert scores to 16-bit precision in order to pack them into an int along with a neighbor ordinal The result was about a 16% improvement in indexing times, and fewer, smaller GC pauses noted in profiler. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
