------------------------------------

             Summary: FilterNode set estimated data size to unknown
                 Key: FLINK-1150
                 URL: https://issues.apache.org/jira/browse/FLINK-1150
             Project: Flink
          Issue Type: Bug
          Components: Optimizer
    Affects Versions: 0.6.1-incubating, 0.7-incubating
            Reporter: Fabian Hueske
            Assignee: Fabian Hueske


The default selectivity estimate of a Filter is 0.5.
During optimization, the FilterNode correctly adapts the estimated cardinality but sets the
estimated data size to unknown.
