-----------------------------
Issue & fix info: Patch Available
> Document performance issue with 2-arg versions of setXXXStream methods for
> LOBs
> -------------------------------------------------------------------------------
>
> Key: DERBY-5698
> URL: https://issues.apache.org/jira/browse/DERBY-5698
> Project: Derby
> Issue Type: Improvement
> Components: Documentation
> Affects Versions: 10.8.2.2
> Reporter: Kim Haase
> Assignee: Kim Haase
> Attachments: DERBY-5698.diff, DERBY-5698.stat, DERBY-5698.zip

>
> The PreparedStatement.setAsciiStream and other methods have a 3-arg form that
> includes the length of the stream and a 2-arg form that does not. If the
> 2-arg form is used, Derby has to calculate the length every time the method
> is called. With LOBs, especially large ones, this can cause a major
> performance impact, especially if the method is called repeatedly. This
> should be documented where appropriate.
> Kristian, please feel free to correct or amplify anything I've said here.
