This announcement is for PDL Snowflake Customers

If you are a current PDL customer receiving data through Snowflake, please read this announcement regarding the upcoming changes to the Snowflake Table Schemas scheduled for the May 2024 (v26.1) release.

⚠️ Snowflake Schema Standardization

Change Expected In: v26.1 / May 2024

As announced in our previous release notes (linked above) we will be standardizing our Snowflake Person and Company Schemas in May 2024 (v26.1). This will be a breaking change to our existing Snowflake schema, and so this announcement aims to provide some additional resources and information to prepare our customers for the transition.

How to Prepare for the Transition

Before the May 2024 (v26.1), we strongly suggest you:

  1. Make a copy of your current data after your April 2024 delivery. This way you not only have a backup, but can also compare new to old after you switch over.
  2. Go through the new standard schemas, which are included in the Resources section below as well as here
  3. Prepare any script changes to your existing processes before the switch in May 2024.

For any questions or help transitioning to these new schema, please reach out to your Customer Success Manager.


Standard Schemas

We now have explicit documentation of the Person and Company Snowflake Schemas that will go into effect with the May 2024 Release (v26.1). We encourage our snowflake customers to ensure their data pipelines can support the specifications linked below. These documents are also linked in the Data Delivery Using Snowflake page as well.

Snowflake Data Sample

In addition, we will also have some sample data in these new schema formats available for customers to test with to ensure their data pipelines fully support the upcoming changes.
