Logstash Indices

What is the best way to take 1 datastream, 1 input and run 2 parallel filters out of it for 2 different indices .

Pipeline-to-pipeline communication using a distributor pattern.

Same data, so I cant specify type, I need the same data with two seperate filters that will come out as 2 different indices.
the two streams are used for different purposes
Is duplicating the data the right way to do it ?

I think so. Just unconditionally send the data to two pipelines.
