If CompassGps mirroring is used with Hibernate, what happens if the database transaction rolls back? Will the changes to the index be rolled back (assuming file store for the index)?
It seems like if the Lucene index is stored on the disk it won't be automatically rolled back, unless Compass is smart enough to handle that for you.

When developing or running a spring mvc app locally that uses hibernate, it would be nice if I could get the output of all sql to a seperate file.
