Summary: Improve Event-Time OVER ROWS BETWEEN UNBOUNDED PRECEDING
aggregation to SQL
Key: FLINK-6204
URL: https://issues.apache.org/jira/browse/FLINK-6204
Project: Flink
Issue Type: Bug
Components: Table API & SQL
Reporter: sunjincheng
Assignee: sunjincheng
Currently `event time OVER ROWS BETWEEN UNBOUNDED PRECEDING aggregation to SQL`
implementation class: ` UnboundedEventTimeOverProcessFunction` use data size
uncontrollable memory data structures`sortedTimestamps: util.LinkedList [Long]
cache data timestamps and sort timestamps. IMO,It's not a good way, because in
the production environment there are millions of window data pre millisecond in
our application scenario.So, I want to improve it. Welcome anyone to give me
feedback.
