Job Scheduler Threads

The Job Scheduler is the process in charge of running all the jobs within Datameer. It requires one controller thread for the coordination of tasks and a possibility of an infinite amount of worker threads that are in charge of running jobs in parallel.

To set the number of Job Scheduler worker threads:

In Datameer, navigate to the Admin tab
Click on Job Scheduler from the menu on the left.
Enter the number of threads available for Job Scheduler tasks.
Click Save.

Event Bus Threads

The Event Bus collects all the metadata changes for all processable Datameer artifacts. (E.g., import jobs, data links, workbooks, etc...). The number of threads determines when to resolve tasks triggered by events published by the Event Bus. When an event begins, all registered subscribers for an event are run in sequence.

These threads are used to resolve tasks triggered by events published through the event bus

To set the number of Event Bus threads:

In Datameer, navigate to the Admin tab
Click on Event Bus from the menu on the left.
Enter the number of threads available for Event Bus tasks.
Click Save.
