Cassandra does not expire data after setting timeToLive argument for each value
-------------------------------------------------------------------------------
Key: CASSANDRA-1109
URL: https://issues.apache.org/jira/browse/CASSANDRA-1109
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 0.6.1
Reporter: Jignesh Dhruv
Hello,
I downloaded the latest cassandra code from svn trunk. I wanted to test the
expire data functionality. Using Thrift API, I set the timeToLive parameter for
each value, however cassandra ignored it and did not expire any data.
I debugged the source code and found a bug in
src/java/org/apache/cassandra/db/RowMutation.java.
In RowMutation.addColumnOrSuperColumnToRowMutation() method, QueryPath was not
setting the timeToLive argument. I updated the code locally and tested it and
then my data expired after 'n' number of seconds.
I wanted to have this fix in the trunk also.
