API today merges all provided readers into a single merge, in one large blocking call. We want to add concurrency here by invoking multiple parallel merges on subsets of readers, in a way that is configurable by users. The merged segments created, can later be merged further in the regular, non-blocking, background merges triggered by Lucene. Currently, users are responsible for managing their API run times, by invoking it multiple times with subsets of readers. JIRA - https://issues.apache.org/jira/browse/LUCENE-10216 # Solution In this change, we leverage the configured MergeScheduler to invoke all merges required by the addIndexes API. MergePolicy also exposes a `findMerges(List<CodecReader> readers)` API that users can override to configure how their readers should be clustered into merges. We add a default implementation that retains current behavior of adding all readers into a single merge. # Tests - Existing tests passing - Pending: New tests to be added # Checklist Please review the following and check all that apply: - [ ] I have reviewed the guidelines for [How to Contribute](https://wiki.apache.org/lucene/HowToContribute) and my code conforms to the standards described there to the best of my ability. - [ ] I have created a Jira issue and added the issue ID to my pull request title. - [ ] I have given Lucene maintainers [access](https://help.github.com/en/articles/allowing-changes-to-a-pull-request-branch-created-from-a-fork) to contribute to my PR branch.
