Subject [jira] [Created] (CASSANDRA-10576) Thrift CAS on static columns doesn't work as expected
Date Fri, 23 Oct 2015 14:06:27 GMT
Sam Tunnicliffe created CASSANDRA-10576:
-------------------------------------------

             Summary: Thrift CAS on static columns doesn't work as expected
                 Key: CASSANDRA-10576
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10576
             Project: Cassandra
          Issue Type: Bug
            Reporter: Sam Tunnicliffe
            Assignee: Sam Tunnicliffe
             Fix For: 3.0.0


Although the thrift cas call works as expected for dynamic column families, using it on tables
with statically defined columns produces unexpected results. The problem, in {{ThriftCASRequest}},
is that while the {{expected}} partition contains a static row, the {{current}} partition
has been processed by {{ThriftResultsMerger}} during the read, converting the static columns
to clusterings. If {{expected}} contains only a static row, no further checking is carried
out, {{appliesTo}} erroneously returns true and the conditional update is performed regardless
of the current state of the partition.
