BETA: This component is mostly stable but breaking changes could still be made outside of major version releases if a fundamental problem with the component is found.
Executes a command, runs it as a subprocess, and consumes messages from it over stdout.
Messages are consumed according to a specified codec. The command is executed once and if it terminates the input also closes down gracefully. Alternatively, the field
restart_on_close can be set to
true in order to have Benthos re-execute the command each time it stops.
max_buffer defines the maximum message size able to be read from the subprocess. This value should be set significantly above the real expected maximum message size.
The execution environment of the subprocess is the same as the Benthos instance, including environment variables and the current working directory.
The command to execute as a subprocess.
A list of arguments to provide the command.
The way in which messages should be consumed from the subprocess.
Whether the command should be re-executed each time the subprocess ends.
The maximum expected size of an individual message.
