benwtrent opened a new pull request, #13190: URL: https://github.com/apache/lucene/pull/13190
This commit adds a new interface to all MergeScheduler classes that allows the scheduler to provide an Executor for intra-merge parallelism. The first sub-class to satisfy this new interface is the ConcurrentMergeScheduler (CMS). In particular, the CMS will limit the amount of parallelism based on the current number of mergeThreads and the configured maxThread options. Parallelism is now added by default to the SegmentMerger where each merging task is executed in parallel with the others. Additionally, the Lucene99 HNSW codec will use the provided MergeScheduler executor if no executor is provided directly.
