Michael McCandless resolved LUCENE-1149.
----------------------------------------
Resolution: Duplicate
I believe LUCENE-1274 (separation of prepareCommit & commit) already provides
the low level support for building XA transactions on top of Lucene?
> add XA transaction support
> --------------------------

> Key: LUCENE-1149

>
> Need to add XA transaction support to Lucene.
> Without XA support, it is difficult to keep disparate resources (e.g.
> database) in sync with the Lucene index.
> A review of the XA support added to Hibernate might be a good start (although
> Hibernate almost always uses a XA capable backing store database).
> It would be ideal to have a combined IndexReaderWriter instance, then create
> a XAIndexReaderWriter which wraps it.
> The implementation might be as simple as a XA log file which lists the XA
> transaction id, and the segments XXX number(s), since Lucene already allows
> you to rollback to a previous version (??? for sure, or does it only allow
> you to abort the current commit).
> If operating under a XA transaction, the no explicit commits or rollbacks
> should be allowed on the instance.
> The index would be committed during XA prepare(), and then if needed
> rolledback when requested. The XA commit() would be a no-op.
> There is a lot more to this but this should get the ball rolling.
