Last updated on MARCH 11, 2021

Applies to:

Oracle Utilities Customer to Meter Base - Version 2.6.0.1.0 and later
Information in this document applies to any platform.

Goal

As per DBA Guide the partitioning strategy for D1_INIT_MSRMT_DATA table is as below in case we are not using ILM.

PARTITION BY RANGE (D1_TO_DTTM)
SUBPARTITION BY RANGE (MEASR_COMP_ID)

The sub partitioning is based on MEASR_COMP_ID which is not the Primary Key , The PK is INIT_MSRMT_DATA_ID.
What is the performance gain perspective of using MEASR_COMP_ID instead of INIT_MSRMT_DATA_ID?
