Case IDs increase daily by 1000

Root Cause

From Pega Platform 8.3, the API used to create the case ID has changed. In a multinode environment, the idGenerator/defaultBatchSize Dynamic System Setting (DSS) value determines the batch IDs allocated to different nodes.

For example:

In this scenario, the DSS value is 1000 and two nodes are present. 

The request received for case creation by Node 1, created the case ID from 1-1000.
The request received by Node 2 created a case ID from 1001-2000.

Hence, the sequence is not the same as it was earlier. This is performed only when case creation is in a large number on a daily basis, in order to increase performance.


Perform the following local-change to maintain the sequence strictly:

Set the idGenerator/defaultBatchSize DSS value to 1 since the number of case creation is less.
