Project description

Light python framework for AWS SWF

Project

Focus of this project

Similar projects exists (like Simpleflow which seems mature). Here is where Caravan differs from existing projects:

  • Support of AWS Lambda tasks

  • Boto3

  • KISS

  • Bring your own workflow framework (standard implementations as contribs)

  • No coupling between Decider code and Activity code

  • Paster compatible config file

Features

  • Decider worker

  • Activity task worker

  • Commands to start/signal/terminate an arbitrary workflow execution

  • Command to list open workflow execution

  • Command to register a domain

Usage

Setup a SWF for the example:

$ caravan-domain-register -n CaravanExample --retention-days 1

List open execution for last 24h:

$ caravan-list -d CaravanExample

List open execution for year 2015:

$ caravan-list -d CaravanExample --oldest 2015-01-01

Run the decider:

$ caravan-decider -d CaravanExample -m caravan.examples.demo -t default

Start an execution:

$ caravan-start -d CaravanExample -n Demo -v 0.1 -i 1

Send a signal to an execution:

$ caravan-signal -d CaravanExample -i 1 -s PAYMENT_CONFIRMED

Terminate an execution:

$ caravan-terminate -d CaravanExample -i 1
