> At the moment, there is no feature that enables associating user information to the commit point.
>  
> Lucene supports this possibility and it should be exposed to solr as well, probably via beforeCommit Listener (analogous to prepareCommit in Lucene).
> Most likely home for this Map to live is UpdateHandler.
> Example use case would be an atomic tracking of sequence numbers or timestamps for incremental updates.
