An input is a source of data piped through an array of optional processors:
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 Benthos 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.
Only one input is configured at the root of a Benthos config. However, the root input can be a broker which combines multiple inputs and merges the streams:
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
Sometimes it's useful to generate data, in which case the most convenient option is the
