-------------------------------------------
Summary: Followup to 6914: null handling, duplicate column in
resultSet and cleanup
Key: CASSANDRA-7155
URL: https://issues.apache.org/jira/browse/CASSANDRA-7155
Project: Cassandra
Issue Type: Bug
Reporter: Sylvain Lebresne
Assignee: Sylvain Lebresne
Priority: Minor
The patch for CASSANDRA-6914 left a few stuffs not properly handled:
# A condition like {{IF m['foo'] = null}} is not handled and throw a NPE.
# It's using ByteBuffer.equals() to compare 2 collection values which is
generally incorrect (the actual comparator should be used).
# If 2 conditions on 2 elements of the same collection were provided and the
CAS failed, then the collection was duplicated in the resultSet.
# The ColumnCondition.WithVariables was generally a bit inefficient/ugly: it
can lead to bind multiple times the same terms which is unnecessary. It's
cleaner to directly create a condition with bound values.
