Purging data

You can purge the data of your organization. When you purge data, you permanently delete data from the data store without deleting data models and other configuration details.
You can choose to purge all business entity records, source records, and relationships, along with historical data. You can also choose to purge all historical data from business entity records, hierarchies, and relationships or purge records that belong to a specific business entity.
You can purge data in the development, QA, and production environments. When you purge data, a purge job is automatically created and triggered.

Rules and guidelines for purging data

Before purging data, consider the following rules and guidelines to prevent any data issues:

Performance considerations for purging data

The performance of data purge depends on the data set, data volume, and POD-level limits.
To optimize performance of data purge, consider the aspects of data, such as volume and complexity, and purging limits.

Complexity of the data set

The performance of purge jobs depends on the size and complexity of your data set, such as the number of relationships, source records associated with master records, number of record pairs generated for matching, and historical data.

Small volume data purge

When you purge up to 1,000 master records or deleted source records, the purge job runs immediately without queuing.

Large volume data purge

You can purge up to 1 million master records at a time. To purge larger volumes, run the purge job multiple times.
You can purge up to 10 million deleted source records. To ensure proper scheduling and resource allocation for purging volumes exceeding 1 million records, contact Informatica Global Customer Support.
For information about viewing the number of master records and source records in your organization, see Monitor MDM SaaS.

Concurrency limits at the POD level

Informatica limits the number of concurrent purge jobs on a POD to three. As a result, your purge job might be queued if multiple jobs run concurrently on a POD.
