How to handle buffer data between processors chain

[licongchao]

Benthos is fantastic. I'm looking into it to solve some data processing requirements.
The requirements is to collect data from external service and do some data processing. i already added a customized input and working on the customized processor. The processor output should be buffered when specific logic/condition meets (Wait for other data to arrive and do periodical timer to deliver output result).
Is this logic suitable to be placed in the processor?

Hey @licongchao, there are buffer plugins which sound like they suit your use case better: https://pkg.go.dev/github.com/benthosdev/benthos/v4@v4.23.0/public/service#Environment.RegisterBatchBuffer
