Thank you for this PR @hequn8128. I could not spot any issues with the
implementation. I tested it on a query with TPC-H data and compared it with
batch results. I will merge this now.
However, I'm wondering if we can further improve the performance of the
implementation by the recently added possibility of changing/deleting timers
(FLINK-9440). What do you think?---
