> Affects Versions: 2.0.0, trunk, 3.0.0

> ***Background*
> Atlas patch handler is a framework that applies changes made to the structure
> of the data. Latest update to the _ConcurrentPatchProcessor_ is missing the
> commit statement. This causes changes not to get applied.
> *Solution*
> Since _ConcurrentPatchHandler_ uses the _PC_ framework, calling the
> _ConcurrentPatchProcessor_.doCommit after
> _individualItemProcessor.processVertexItem_ will address the problem.
> *Impact*
> The _commit_ is finally called when the data is exhausted, only that until
> then the data is held in memory. This may be OK for really small data but
> does not work for medium to large size data. The result is out of memory
> exception, since _JanusGraph_ holds all these changes in memory waiting for
> commit to be called.
