2 min read

Queue Scheduler is used to execute Extraction Processes which use Queue Fetcher based on Glue Queue contents. The corresponding Extraction Process(es) is executed when a Queue contains data. Processes with the oldest execution timestamp are prioritized.

Parameters:

Package size (MB)

Size in MB of one package transferred during Extraction Process execution

Allow parallelization

If there are spare jobs, Extraction Processes that are already running can be executed again transferring the data in parallel

Debug log level

(can be changed during scheduler runtime)

0: No logs

1: Standard - debug logs without specific Extraction Process names

2: Extended - debug logs with Extraction Process names included

Max process runtime (minutes)

Maximum execution time in minutes for one Extraction Process (to avoid jobs being blocked by the same Extraction Process for extensive periods)

Max number of jobs

Maximum number of jobs that can be used by the scheduler (scheduler job not included)

Max jobs used for full loads (%)

Percentage of jobs that can be used for full loads (so the delta execution is not blocked for longer periods)

ALV grid

List of Extraction Processes processed by the scheduler

ALV Grid

Glue queue: Name of Glue Queue object.

Extraction Process: Name of Extraction Process object.

Variant (optional): When specified, the Extraction Process will be executed with the chosen Variant.

Overwrite variant: Parameter Package size value provided on the Scheduler screen will be used over the value of the parameter Package size that the variant stores.

Last start: Date and time of the last start of extraction.

Status: The icon is displayed in case the extraction is running.

Load mode: Load mode of the last executed extraction.
