Veena Basavaraj commented on SQOOP-1810:
----------------------------------------
The patch contains the following
1. A new IncrementalWriteConfig similar to IncrementalRead, it has a enum that
expects a value for type of writes to happen
a. INSERT ( default)
b. UPSERT ( insert or update ), for new rows will be inserted
c. UPDAT ( only updates, new rows are left)
Not in the patch
d. DELETE ( in future even support deleting records if need be )
2. Changes to the Loader to use the relevant JDBC statements, such as INSERT or
UPDATE based on the primary key
3. The integration test to assert the insert / upsert happened
> GenericJdbcConnector : ToJobConfiguration and Loader enhancements for
> Incremental write ( INSERT or UPDATE)
