@Tarun Namdev You can use dynamic filtering to check black listed customer https://selectfrom.dev/dynamic-filtering-in-flink-af6939f3da2e For the number transaction more than 10 you can use Filnk Windowing Based on your requirement I think you can use Tumbling window https://nightlies.apache.org/flink/flink-docs-master/docs/dev/datastream/operators/windows/
