In Apache Solr, is there a way to determine whether a core has any uncommitted/staged changes?

I would like to implement a more rigorous transaction/concurrency model in my client than Solr itself implements. One key piece to this is determining whether there are any uncommitted/staged changes in a core in Solr. Is there a request I can make to Solr from a client to figure this out?

You can query the metrics API - the UPDATE.updateHandler segment will have the docsPending value set:

UPDATE.updateHandler.docsPending: Number of documents which are pending commit.

There's also the adds stats:

UPDATE.updateHandler.adds: Total number of “add” requests since last commit.

These stats are available per core.
