Performance degrades when running Distribution test



In the production system, running a Distribution test for an Outbound Marketing Campaign for a segment containing 500,000 users takes more than five hours. However, in the Acceptance test with a comparable segment, the Distribution test runs for 20 minutes.

Set the Marketing setting to enable partitioning to True (Data Partitioning on PartitionKey is always set to value 1).

Error Messages

Not Applicable

Steps to Reproduce

Run the same campaign in two different systems.

Root Cause

The history table size was checked.

Query select count(*) from PR_DATA_IH_FACT:

Production system: 17 153 741 rows 
Acceptance system: 344 060 rows 

A lot of time was spent on the Interaction History Shape. The Interaction History table was larger in production. As a result, campaign runs took a long time to complete.


As a local-change, enable partitioning to distribute the campaign run.
