bq. Summary
bq. -------
bq.
bq. When the current kv is deleted during the matching in the
ScanQueryMatcher, currently the matcher will return skip and continue to seek.
bq. Actually, if the current kv is deleted because of family deleted or column
deleted, the matcher should seek to next col.
bq. If the current kv is deleted because of version deleted, the matcher
should just return skip.
bq.
bq. I will submit another patch against apache-trunk later.
