Workflow service overview
|
|
=================================
|
|
|
|
Mistral is a workflow service that enables setting up and scheduling tasks and
|
|
task relations that have to be executed in a particular order, called workflows.
|
|
During execution, Mistral handles state management, correct execution order,
|
|
parallelism, synchronization and high availability.
|
|
|
|
Mistral can be used, for example, for Cloud Cron-style task scheduling,
|
|
Cloud Environment Deployment, handling long-running business processes, managing
|
|
BigData analysis and tasks, and live migration.
|
|
|
|
The Workflow service consists of the following components:
|
|
|
|
``Mistral API`` service
|
|
Provides a REST API for operating and monitoring workflow executions.
|
|
|
|
``mistral-dashboard`` service
|
|
Mistral Dashboard is a Horizon plugin.
|
|
|
|
``Mistral Engine`` service
|
|
Controls workflow executions and handles their data flow, places finished
|
|
tasks in a queue, transfers data from task to task, and deals with condition
|
|
transitions, and so on.
|
|
|
|
``Mistral Executor`` service
|
|
Executes task actions, picks up the tasks from the queue, runs actions, and
|
|
sends results back to the engine.
|
|
|
|
``Mistral Notifier`` service
|
|
|
|
``python-mistralclient``
|
|
