adding bolt to TridentTopology

[Naga Vij <nv...@gmail.com>]

Hello,

How can I add a bolt to TridentTopology?

I realize the use of function on the stream (kafka stream in my case) ...

parsedStream.each(parsedStream.getOutputFields(), new SomeFunction(), new
Fields());

But I want to do subsequent processing by using bolts after the function.

How can I do that?  Tried looking into the API, but appears I need some
help from others who might have tried it already.

Thanks in advance.

You can not use storm core bolts to process trident tuples. You could use core spouts in trident topologies but not  bolts.
You will have to write your trident states that may do identical stuff as your bolt implementation in batch mode. You can refer to this doc to understand how you can write your own trident state 
https://storm.incubator.apache.org/documentation/Trident-tutorial.html

Hope this helps.

Thanks
Parth
