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.
Cheers,
Till
