Hi , I have a flink real time job which processes user records via topic and also reading data from hbase acting as a look table . If the look table does not contain required metadata then it queries the external db via api . First 1to 2 hours it works fine without issues, later it drops down drastically to 30 TPS. What are the things I need to look into in such a situation? There are no exceptions caught . how to check the bottle neck area . can some throw some light on this.
Thanks & Regards Ragini Manjaiah
