Vinoth Chandar commented on SQOOP-1168:
---------------------------------------
The design doc looks like a good start to me.
>>Can we merge the incremental/ delta update concept together and expose a
>>consolidated construct the the user does not have to >>distinguish?
If I understand the terminology correctly, incremental deals with only new
records, while delta deals with both new and updated records. Is nt delta a
superset of incremental? (I can however think of a case where someone wants
basically an audit log or something, where we fetch new & updated records, but
don't overwrite the record in the destination).
