Subject [jira] [Created] (CASSANDRA-9313) Clarify errors when attempting to write at SERIAL
Date Tue, 05 May 2015 22:54:59 GMT
Brandon Williams created CASSANDRA-9313:
-------------------------------------------

             Summary: Clarify errors when attempting to write at SERIAL
                 Key: CASSANDRA-9313
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9313
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Brandon Williams
             Fix For: 2.0.x


[LOCAL_]SERIAL does not support writes, but the errors can be very confusing if you don't
know this:

{noformat}
cqlsh:foo> INSERT INTO bar (foo ) VALUES ( 'foo' ) ;
InvalidRequest: code=2200 [Invalid query] message="You must use conditional updates for serializable
writes"
cqlsh:foo> INSERT INTO bar (foo ) VALUES ( 'foo' ) if NOT EXISTS ;
InvalidRequest: code=2200 [Invalid query] message="SERIAL is not supported as conditional
update commit consistency. Use ANY if you mean "make sure it is accepted but I don't care
how many replicas commit it for non-SERIAL reads""
{noformat}
