-----------------------------------------
Summary: Sqoop2: Generic JDBC: Drop support for specifying custom
query when exporting data
Key: SQOOP-2441
URL: https://issues.apache.org/jira/browse/SQOOP-2441
Project: Sqoop
Issue Type: Bug
Reporter: Jarek Jarcec Cecho
Assignee: Jarek Jarcec Cecho
Fix For: 1.99.7
In the early days of the development we've added new feature to the JDBC
connector that enabled user to specify custom query to insert the data -
similarly as user can specify custom query to select data. I see several
problems with the feature:
* It's actually not working at all right now because we're not able to
[generate schema from the custom
query|https://github.com/apache/sqoop/blob/sqoop2/connector/connector-generic-jdbc/src/main/java/org/apache/sqoop/connector/jdbc/GenericJdbcToInitializer.java#L66].
* It doesn't allow us to do any batching as we're doing in Sqoop 1 when we're
putting several rows into the same query which will hurt performance.
* I did not see any real request for this feature from users
Hence I would like to propose dropping this unfinished/non-working feature all
together. Any thoughts?
