[jira] [Created] (FLINK-8002) Incorrect join window boundaries for LESS_THAN and GREATER_THAN predicates

Fabian Hueske created FLINK-8002:
------------------------------------

             Summary: Incorrect join window boundaries for LESS_THAN and GREATER_THAN predicates
                 Key: FLINK-8002
                 URL: https://issues.apache.org/jira/browse/FLINK-8002
             Project: Flink
          Issue Type: Bug
          Components: Table API & SQL
    Affects Versions: 1.4.0
            Reporter: Fabian Hueske
            Assignee: Fabian Hueske
            Priority: Critical
             Fix For: 1.4.0


The boundaries of LESS_THAN and GREATER_THAN predicates are not correctly computed if the time attribute of the right table is referenced on the left side of the join predicate.
Instead of adding (subtracting) 1 millisecond, 1 millisecond is subtracted (added). 
Hence, the boundary is off-by-2.
