Informations about the package task
Flow Framework Task Scheduler
This package provides a simple to use task scheduler for Neos Flow. Tasks are configured via settings, recurring tasks can be configured using cron syntax. Detailed options configure the first and last executions as well as options for the class handling the task.
Scheduling and running tasks are decoupled: The Scheduler
schedules tasks whcih the are executed by the TaskRunner
. This architecture allows receiving and displaying metrics of already executed tasks.
Most of the architectural ideas behind the package are taken from php-task, and reimplemented for Neos Flow.

Implementing A Task Handler
A task handler contains the code executed for a specific task. Your command handler has to implement one of the following interfaces:
Flowpack\Task\TaskHandler\TaskHandlerInterface
A basic task. The interface requires the method handle(WorkloadInterface $workload): string
to be implemented. The return value serves as information for successfully executed tasks.
Flowpack\Task\TaskHandler\RetryTaskHandlerInterface
Also requires getMaximumAttempts(): int
to be implemented. Allowing the tasks to be retried on failure.
Flowpack\Task\TaskHandler\LockingTaskHandlerInterface
Also requires getLockIdentifier(WorkloadInterface $workload): string
to be implemented. The return value specifies a lock to be acquired. When such a task is running, other tasks requiring the same lock will be skipped.
