Custom Indexes for Base Objects

Custom Indexes for Base Objects

You can create custom indexes to improve batch job and SIF API performance.
Informatica MDM Hub creates system indexes for primary keys and unique columns. Optionally, you can create custom indexes for the other columns to increase performance. The values in a custom index might not be unique.
For example, an external application might call the SearchQuery SIF API request to search a base object by last name. If you create a custom index on the last name column, search performance improves.
Batch jobs drop and re-create system indexes and registered custom indexes to increase performance. Use the RegisterCustomIndex SIF API to register the custom indexes.
You cannot create a custom index if a global business identifier index exists for the base object. Base objects have a global business identifier index when you enable any of the base object columns to be a global business identifier.
Because of Microsoft SQL Server limitations, you cannot create a custom index with more than 16 columns with
running on Microsoft SQL Server.
