Sylvain Lebresne commented on CASSANDRA-7206: --------------------------------------------- bq. The validation code in {{UserTypes}} still checks for field value {{< FBUtilities.MAX_UNSIGNED_SHORT}} That's an oversight from CASSANDRA-6855. I've simply committed the removal of that check and updated the patch here accordingly. > UDT - allow null / non-existant attributes > ------------------------------------------ > > Key: CASSANDRA-7206 > URL: https://issues.apache.org/jira/browse/CASSANDRA-7206 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Robert Stupp > Assignee: Sylvain Lebresne > Fix For: 2.1 rc1 > > Attachments: 7206.txt > > > C* 2.1 CQL User-Defined-Types are really fine and useful. > But it lacks the possibility to omit attributes or set them to null. > Would be great to have the possibility to create UDT "instances" with some > attributes missing. > Also changing the UDT definition (for example: {{alter type add new_attr}}) > will break running applications that rely on the "previous" definition of the > UDT. > For exmple: > {code} > CREATE TYPE foo ( > attr_one text, > attr_two int ); > CREATE TABLE bar ( > id int, > comp foo ); > {code} > {code} > INSERT INTO bar (id, com) VALUES (1, {attr_one: 'cassandra', attr_two: 2}); > {code} > works > {code} > INSERT INTO bar (id, com) VALUES (1, {attr_one: 'cassandra'}); > {code} > does not work > {code} > ALTER TYPE foo ADD attr_three timestamp; > {code} > {code} > INSERT INTO bar (id, com) VALUES (1, {attr_one: 'cassandra', attr_two: 2}); > {code} > will no longer work (missing attribute) -- This message was sent by Atlassian JIRA (v6.2#6252)
