> Do we need some other objects like FunctionalBasedIndex (like > CREATE UNIQUE INDEX MY_UPPER_IDX on MY_TABLE(upper(LOGIN)) > or even combine it with partial one, like: > CREATE UNIQUE INDEX MY_UPPER_IDX on MY_TABLE(upper(NAME)) WHERE (deleted = false) Let's add functional index support within a separate ticket. A functional index can't be UNIQUE because it is not columnar index, but UNIQUE index must contain all affinity columns. UNIQUE index on arbitrary columns/values will be very slow on update operation and we won't support this case. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
