[jira] Created: (DERBY-3855) The Tuning guide should mention that LIKE transformations/optimizations are disabled when using territory-based collations

The Tuning guide should mention that LIKE transformations/optimizations are disabled when using territory-based collations
--------------------------------------------------------------------------------------------------------------------------

                 Key: DERBY-3855
                 URL: https://issues.apache.org/jira/browse/DERBY-3855
             Project: Derby
          Issue Type: Improvement
    Affects Versions: 10.4.1.3, 10.3.3.0, 10.5.0.0
            Reporter: Rick Hillegas


The Tuning Guide section titled "LIKE transformations" describes transformations and optimizations which Derby performs on LIKE expressions in order to avoid full table scans. These transformations/optimizations are disabled when using territory-based collations. See DERBY-3854. The Tuning Guide does not mention this fact but it is likely that this information would be very useful to customers and tech support engineers. The "LIKE transformations"  section in the Tuning Guide should be changed to mention that LIKE transformations/optimizations are disabled when using territory-based collations.

                DERBY-3855.diff

This seems like a fairly simple fix, Rick, with all the information you provided. Attaching DERBY-3855.diff and rtuntransform208.html, which I hope are correct. I added a cross-reference to the main information about territory-based collation in the Dev Guide.

Hi Kim,

It looks like it took me more words to describe the problem than it took you to fix it. This looks good to me. +1
