incremental load from kafka to memsql [closed]

edit

I have a streaming job having kafka consumer as source and i want to load the data to memsql database. I am currently using jdbc producer to connect to memsql. i could load some data through insert operation to memsql. But i am not sure how to perform the incremental updates based on kafka source. can anyone please help me with the approach. i saw some documents using sdc.operation.type but not sure where and how to use this attribute
