Currently we have the capacity of applying index changes using the property hibernate.search.default.worker.execution = async, which in turn will use an Executor to apply each changeset in a background thread. Still, commits are done on every changeset: it'd be nice if we have the possbility of controlling commits based on a time based configuration property like commitInterval where multiple changesets would be included on each commit. Performance gain is significant on scenarios where changesets are small (usually one or two docs).
