> The DBOutputFormat adds a semi-colon to the end of the INSERT statement that it uses
to save fields to the database.  Semicolons are typically used in command line programs but
are not needed when using the JDBC API.  In this case, the stray semi-colon breaks rewriteBatchedStatement
support. See: http://forums.mysql.com/read.php?39,271526,271526#msg-271526 for an example.
> In my use case, rewriteBatchedStatement is very useful because it increases the speed
of inserts and reduces memory consumption.
