reaktion-next

workflow scheduler for arkitekt

Idea

reaktion is a scheduler extension for rekuest, it hooks into the agent and provides the "Deploy Flow" Node, that allows users to choose the app as a scheduler for their workflows. When deploying a flow, this plugin will create a new workflow node, which can now be reserved by any external app.

When reserving a workflow node, the plugin will create a new "Flow" Actor, which will be responsible for the execution of the workflow. This actor will keep track of the state of the workflow and acts as the scheduler.

Prerequesits

Services: In order to use reaktion_next you need a working arkitekt server with both "rekuest" (remote app calling-service) and "fluss" - (workflow design and run recording module)" installed.

Client: you need to install arkitekt-next with the "reaktion_next" extra enabled

Use inside an Arktiekt "Plugin"App

Add the reaktion_next import to your imports

from arkitekt_next import register
import reaktion_next # autoinstalls the scheduling extensions

@register
def do_something() -> None:
    """ Some other random installed functionaliry that is also provided """

Start your app via "arkitekt-next run dev". You should now see the reaktion badge appear on the AgentPage and you will find the scheduler in the Deploy Button subsection when deploying your app.

Use inside an Arkitekt "Standalone App"

from arkitekt import register, easy
import reaktion_next # autoinstalls the scheduling extensions

@register
def do_something() -> None:
    """ Some other random installed functionaliry that is also provided """



with easy("your_app_name", url="arkitekt-server-ulr") as e:
   e.run() # will start a normal arkitekt app with reaktion enabled

Experimental: Local Scheduling

An Arkitekt app that imports reaktion_next can also run entire local workflows the will call registered function in memory, and does not to copy data from and to the arkitket server.
