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
