> 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?
