Description

We are ingesting from a Pubsub Read and are attempting to mimic the maxNumRecords that was available in 0.6.0. In order to do this we would need to utilize withMaxNumRecords from the BoundedReadFromUnboundedSource class. We would need to utilize the PubsubSource class to create the UnboundedSource from Pubsub. Would it be possible to expose PubsubSource? Currently what is the recommended way to create a bounded read from Pubsub with a set number of records?
