Steven Hawkins updated TEIID-2495:
----------------------------------
Attachment: teiid.patch
Patch showing a sketch of update batching based upon the transaction. This would need
refined (remove binding to allow for source batching, detect bulk, handling for generated
keys, rowcount, etc.) and moved to the transactioncontext so that all updates could be
trapped - otherwise a similar datamanager would be needed in ForEachRowPlan but both would
miss lower level queries (such as actions triggered by matview queries).
Detect situations in which intermediate updates are not needed such
that the updates can be grouped
