-------------------------------------------------------------
Ok I was looking at the 1.8 docs I missed the mention of checkpoint, but I was
also looking JDBCOutputFormat. So I guess for 1.8 the functionality goes as
this...
JDBCOutputFormat: Simplest to use only sinks by batch size interval.
JDBCSinkFunction: Uses JDBCOutputFormat but is also checkpoint enabled for at
least once.
JDBCAppendTableSink: Uses JDBCSinkFunction and integrates with the table APIs.

> Affects Versions: 1.8.0, 1.8.1, 1.8.2, 1.9.0
> Reporter: None none
> Priority: Minor

> Currently the JDBC sink/output does not support checkpointing. It would be
> advantageous to enable checkpointing on JDBC sinks for Dbs that have
> transactional support.
