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 prop= agate the incoming frames to all branches and T value in the =1BT-occurrenc= e problem is calculated twice for the same tuple.
