> I would like to propose a TwoPhaseCommit interface which declares the methods necessary to implement a 2-phase commit algorithm:
> * prepareCommit()
> * commit()
> * rollback()
> The prepare/commit ones have variants that take a (Map<String,String> commitData) following the ones we have in IndexWriter.
> In addition, a TwoPhaseCommitTool which implements a 2-phase commit amongst several TPCs.
> Having IndexWriter implement that interface will allow running the 2-phase commit algorithm on multiple IWs or IW + any other object that implements the interface.
> We should mark the interface @lucene.internal so as to not block ourselves in the future. This is pretty advanced stuff anyway.
> Will post a patch soon
