Grouping

The PO to PME ETL includes a new grouping feature that breaks the device-topic pairs that the ETL job processes into groups. Grouping processes a subset of all device-topic pairs (or tags) concurrently each time the job runs, thereby increasing the concurrent action within the job and improving performance.

Grouping is enabled by selecting Process item groups across multiple job runs (on the Advanced tab.)

How grouping groups and processes device-topic pairs is determined by the following settings: 

Advanced tab:

• Max Data Request Per Group
• Max Groups Per Job Run

PO Extract Task settings:

• Data Request Record Size
• Maximum Number of Requests

For information on how to use the grouping settings, see PO to PME ETL job performance .
