Hi Ramya, which configuration options do you wanna change at runtime? Flink's cluster configuration is read at start up of the cluster and cannot be changed during its lifetime. If you want to change the behaviour of an operator, then this is possible. One way could be to use a CoMapFunction which uses one input stream as a control stream to reconfigure the operator. The other input stream would be the main stream which is used for processing of streaming records.
Afaik Flink does not come with a MySQL connector. This is something you would need to implement on your own.
