-----------------------------------------
Summary: Use splittable timers in Interval Join
Key: FLINK-38810
URL: https://issues.apache.org/jira/browse/FLINK-38810
Project: Flink
Issue Type: Improvement
Components: Table SQL / Runtime
Reporter: Roman Khachatryan
Assignee: Roman Khachatryan
Fix For: 2.2.1
On timer, TimeIntervalJoin potentially performs a lot of work iterating through
all it's records in state.
And when multiple timers are triggered by a single watermark, checkpoint can be
delayed significantly, effectively increasing e2e latency.
Recently, splittable timer functionality was introduced to Flink for a limited
set of operators.
TimeIntervalJoin can benefit from it as well.
