API usage

At the moment tremor supports a fairly minimal api. A documentation can be found here.

There is one part of the API worth calling out as it is a fairly powerful and completely new concept:

Pause / Resume

With the /v1/flows/{flow-id} call we can pause a flow. Pausing a flow will start the quiescense process and put all connectors in the flow into paused state - meaning they'll not produce any further messsages.

The same can be done with the /v1/flows/{flow-id}/connectors/{connector-id} which will pause only a single connector.


The /v1/status can be used to get status information on the running Tremor cluster and all its deployed Flows. It will error if any of the deployed flows is in an unhealthy state.
