Subject [jira] [Commented] (SQOOP-1810) GenericJdbcConnector : ToJobConfiguration and Loader enhancements for Incremental write ( INSERT or UPDATE)
Date Mon, 23 Mar 2015 18:32:53 GMT

    [ https://issues.apache.org/jira/browse/SQOOP-1810?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14376343#comment-14376343
] 

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
