------------------------------------
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.
