James Taylor commented on PHOENIX-3443:
---------------------------------------
I think the encoding scheme should be specified by a number 0-4 that indicates
how many bytes will be used to encode the column qualifier. A value of 0 would
indicate that the feature is disabled. Otherwise, we'd detect when the column
number value goes beyond the max value based on the number of bytes (we can
just use a long when we do the arithmetic), and in that case throw an error.
Eventually we could potentially support a kind of clean-up procedure that would
reclaim unused columns, but that could be future work if we see demand for it.
The poor mans alternative would be to create a new table and do an upsert
select into it.
> Support different encoding schemes (BYTE, SHORT, INTEGER) for storing encoded
> column qualifiers
