SKIP_SCAN on variable length keys

 Hello,
Im wondering is there any issue with SKIP SCAN when variable length columns used in composite key?
My suspicion comes from FuzzyRowFilter that takes fuzzy row key template with fixed positions

SKIP SCAN doesn't use FuzzyRowFilter. It has its own SkipScanFilter. If you
see problems, please provide more details or file a JIRA for that.

Thanks,
