Scheduler task storage 

Changed in version 14.0

With TYPO3 v14.0 the storage of scheduler tasks switched from the PHP-serialized storage format in the database to a JSON-based format.

The scheduler tasks displayed in backend module System > Scheduler are stored in the database table tx_scheduler_task. Task groups are stored in table tx_scheduler_task_group.

tx_scheduler_task fields 

The database table tx_scheduler_task contains the following fields:

tasktype
Typically contains the fully qualified class name of the task, for example \TYPO3\CMS\Scheduler\Task\CachingFrameworkGarbageCollectionTask or the command name, for example language:update if the task is implemented as Symfony console command.
parameters
The options configuring the task as JSON-encoded value.
execution_details
Contains all details on execution like the type (Recurring / Single), start and end dates and the frequency in which recurring tasks should be executed.

Additionally it stores some information on the last and next execution of the task, and fields for a description and the group.
