Hello fabian,
Thanks for your quick response,
According to above conversation flink will persist state forever for non
windowed operations. I want to know how flink persiat the state i.e.
Database or file system or in memory etc.

Hi Amol,
The memory consumption depends on the query/operation that you are doing.
Time-based operations like group-window-aggregations,
over-window-aggregations, or window-joins can automatically clean up their
state once data is not no longer needed.
Operations such as non-windowed aggregations
