Streams API

When Benthos is run in --streams mode it will open up an HTTP REST API for creating and managing independent streams of data instead of creating a single stream.

Each stream has its own input, buffer, pipeline and output sections which contains an isolated stream of data with its own lifetime.

A walkthrough on using this API can be found here.

API

GET /streams

Returns a map of existing streams by their unique identifiers to an object showing their status and uptime.

Response 200

{
	"<string, stream id>": {
		"active": "<bool, whether the stream is running>",
		"uptime": "<float, uptime in seconds>",
		"uptime_str": "<string, human readable string of uptime>"
	}
}

POST /streams

Sets the entire collection of streams to the body of the request. Streams that exist but aren't within the request body are removed, streams that exist already and are in the request body are updated, other streams within the request body are created.

{
	"<string, stream id>": "<object, a standard Benthos stream configuration>"
}

Response 200

The streams were updated successfully.

POST /streams/{id}

Create a new stream identified by id by posting a body containing the stream configuration in either JSON or YAML format. The configuration should be a standard Benthos configuration containing the sections input, buffer, pipeline and output.

Response 200

The stream was created successfully.

GET /streams/{id}

Read the details of an existing stream identified by id.

Response 200

{
	"active": "<bool, whether the stream is running>",
	"uptime": "<float, uptime in seconds>",
	"uptime_str": "<string, human readable string of uptime>",
	"config": "<object, the configuration of the stream>"
}

PUT /streams/{id}

Update an existing stream identified by id by posting a body containing the new stream configuration in either JSON or YAML format. The configuration should be a standard Benthos configuration containing the sections input, buffer, pipeline and output.

The previous stream will be shut down before and a new stream will take its place.

Response 200

The stream was updated successfully.

PATCH /streams/{id}

Update an existing stream identified by id by posting a body containing only changes to be made to the existing configuration. The existing configuration will be patched with the new fields and the stream restarted with the result.

Response 200

The stream was patched successfully.

DELETE /streams/{id}

Attempt to shut down and remove a stream identified by id.

Response 200

The stream was found, shut down and removed successfully.

GET /streams/{id}/stats

Read the metrics of an existing stream as a hierarchical JSON object.

Response 200

The stream was found.
