Matthew Jacobs commented on KUDU-1570:
--------------------------------------
It looks like this is actually not allowed in the SQL standard (T591 "UNIQUE
constraints of possibly null columns" in the 2003 standard), so I retract my
request for this feature :)
In fact, I'd prefer if we do not add it to Kudu to avoid complications with SQL
mappings (Impala or other SQL engines). [~tlipcon], feel free to close this
JIRA if you agree.
