> 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.
