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).

>  The default processing model is to simply perform the execution for each row, an enhancment would be required for Teiid to detect situations in which intermediate updates are not needed such that the updates can be grouped.
