temporalio-serverlessworkflow

Experimentation about the implementation of (Serverless Workflow)[https://serverlessworkflow.io/] (specifications)[https://github.com/serverlessworkflow/specification/blob/main/specification.md] with (temporalio)[https://www.temporal.io/]

This is based on https://github.com/temporalio/samples-java and tests several use case like :

  • Waiting for an event => implemented with signals in Temporal

Execute the demo

  • First run the worker that will trigger workflows and activities executions
./gradlew -q execute -PmainClass=com.zenika.temporalio.serverlessworkflow.Worker

  • Then to test waiting for event state :

    • Launch the workflow :
    ./gradlew -q execute -PmainClass=com.zenika.temporalio.serverlessworkflow.StarterOnBoarding
    • Get the current Run ID :
    tctl workflow list --workflow_id "onboarding" --open
    • Send the signal HiringFormFilledEvent to the currently running onboarding workflow :
    tctl workflow signal --workflow_id "onboarding" --name "HiringFormFilledEvent" --run_id `tctl workflow list --workflow_id 'onboarding' --open | sed -En '2p' | cut -f 3 -d '|'`
    • Send the signal ContractSignedEvent to the currently running onboarding workflow :
    tctl workflow signal --workflow_id "onboarding" --name "ContractSignedEvent" --run_id `tctl workflow list --workflow_id 'onboarding' --open | sed -En '2p' | cut -f 3 -d '|'`
    • Send the signal IntegrationTrainingEvent to the currently running onboarding-child-integrationtraining child workflow :
    tctl workflow signal --workflow_id "onboarding-child-integrationtraining" --name "IntegrationTrainingEvent" --run_id `tctl workflow list --workflow_id 'onboarding-child-integrationtraining' --open | sed -En '2p' | cut -f 3 -d '|'`
    • Send the signal FirstMonthReviewEvent to the currently running onboarding-child-firstmonthreview child workflow :
    tctl workflow signal --workflow_id "onboarding-child-firstmonthreview" --name "FirstMonthReviewEvent" --run_id `tctl workflow list --workflow_id 'onboarding-child-firstmonthreview' --open | sed -En '2p' | cut -f 3 -d '|'`
    • Send the signal ValidateTrialPeriodEvent to the currently running onboarding workflow :
    tctl workflow signal --workflow_id "onboarding" --name "ValidateTrialPeriodEvent" --run_id `tctl workflow list --workflow_id 'onboarding' --open | sed -En '2p' | cut -f 3 -d '|'`
    • You should be able to see the onboarding workflow ended in the Web UI or the data results in the Shell that first starts the Workflow instance.
