Question

I have some messages whose format will not change but data can change which I want to insert into MySQL db. So I want to create a properties file which can give me column names for the data received and the table name, so that I can create, edit the tables on the fly without restarting my topology. How is it possible to achieve something like that.

Answer 1

As far as my understanding goes, its not possible to change the wiring of bolts or spouts once the topology is submitted.

I am bit confused about how are you planning to receive these information dynamically from a property file. please correct me if I am wrong.
