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

             Summary: indexed edit-distance join can be improved.
                 Key: ASTERIXDB-1820
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-1820
             Project: Apache AsterixDB
          Issue Type: Improvement
            Reporter: Taewoo Kim
            Assignee: Taewoo Kim


The current indexed-edit-distance-join plan uses REPLICATE operator to propagate the incoming
frames to all branches and T value in the T-occurrence problem is calculated twice for the
same tuple. These redundancies can be resolved using SPLIT operator. Refer to the following
doc for more details.
