About

This version of appengine-pipeline library adapted for AppEngine Flexible environment.

It uses following libraries:

• Google Cloud Datastore Java Client (instead of AppEngine Standard DatastoreServiceFactory)
• Google Cloud Tasks Java Client (instead of AppEngine Standard QueueFactory)
• Flex-compatible implementation of Deferred Tasks

Configuration

There are 2 implementation of PipelineTaskQueue interface:

• AppEngineTaskQueue - implementation for Standard environment
• CloudTaskQueue - implementation that uses Cloud Tasks client library

To use CloudTaskQueue you need to set following properties:

• cloudtasks.api.root.url - Cloud Tasks api URL, by default use https://cloudtasks.googleapis.com/
• Optionally cloudtasks.api.key - If you use local implementation of Cloud Tasks use this property to set up API Key to your API
• cloudtasks.api.default.parent - Used to construct correct object names for Cloud Tasks, should use following pattern projects/{applicationId}/locations/{locationId}
• clouddatastore.api.root.url - If you want to use local Cloud Datastore emulator, e.g. http://localhost:8080
• clouddatastore.project.id - for the Cloud Datastore too

Pass properties with your app.yaml:

env_variables:
  JAVA_OPTS: >-
    -Dcloudtasks.api.root.url=https://cloudtasks.googleapis.com/
    -Dcloudtasks.api.default.parent=projects/yourapp/locations/us-central1
