Inputs

An input is a source of data piped through an array of optional processors:

input:
  label: my_redis_input

  redis_streams:
    url: tcp://localhost:6379
    streams:
      - benthos_stream
    body_key: body
    consumer_group: benthos_group

  # Optional list of processing steps
  processors:
   - mapping: |
       root.document = this.without("links")
       root.link_count = this.links.length()

Some inputs have a logical end, for example a csv input ends once the last row is consumed, when this happens the input gracefully terminates and Redpanda Connect will shut itself down once all messages have been processed fully.

It’s also possible to specify a logical end for an input that otherwise doesn’t have one with the read_until input, which checks a condition against each consumed message in order to determine whether it should be the last.

Brokering

Only one input is configured at the root of a Redpanda Connect config. However, the root input can be a broker which combines multiple inputs and merges the streams:

input:
  broker:
    inputs:
      - kafka:
          addresses: [ TODO ]
          topics: [ foo, bar ]
          consumer_group: foogroup

      - redis_streams:
          url: tcp://localhost:6379
          streams:
            - benthos_stream
          body_key: body
          consumer_group: benthos_group

Labels

Inputs have an optional field label that can uniquely identify them in observability data such as metrics and logs. This can be useful when running configs with multiple inputs, otherwise their metrics labels will be generated based on their composition. For more information check out the metrics documentation.

Sequential reads

Sometimes it’s useful to consume a sequence of inputs, where an input is only consumed once its predecessor is drained fully, you can achieve this with the sequence input.

Generating messages

It’s possible to generate data with Redpanda Connect using the generate input, which is also a convenient way to trigger scheduled pipelines.
