------------------------------------------
Summary: Secondary indexes can return stale data for deleted rows
in 2.x
Key: CASSANDRA-13423
URL: https://issues.apache.org/jira/browse/CASSANDRA-13423
Project: Cassandra
Issue Type: Bug
Reporter: Benjamin Lerer
In {{2.x}} when the secondary index detect that a row has been deleted it
removes it from the index. This approach can result in stale data being
returned if one of the nodes has not yet received the deletion.
The problem come from this
{{line|https://github.com/apache/cassandra/blob/cassandra-2.1/src/java/org/apache/cassandra/db/index/composites/CompositesSearcher.java#L284}}.
To avoid that problem we should remove the rows from the indexes only once they
has been garbage collected.
