Delta Lake format lets you track changes to your data over time. When you use Customer Insights with native support for the Delta Lake table format, you can use Delta Lake incremental data updates to speed up processing in Customer Insights - Data.

Customer profile data usually changes by only a small percentage each day. Instead of reprocessing the entire data set every day, Customer Insights - Data processes only the changed source data for unification in the Delta format. This approach saves time and delivers results faster. This improvement happens automatically when all tables use the Delta format. You don't need to set up or change anything.

We plan to add incremental processing for segments, measures, activities, and predictions in future updates.

Updates to the Dataverse connector make it the best choice for importing tables from Dataverse to Customer Insights - Data.

• Performance improvements let you import even the largest Dataverse tables with faster speed.
• Removal of the previous limit that restricted data ingestion to less than two years old data from Dataverse. Now, you can ingest and use all your Dataverse data.
• Improved reliability through importing data in the Delta format, which removes issues common to the .csv format.
• Ability to select only the Dataverse tables you want to use in Customer Insights. You no longer need to select read-only mandatory tables.

The update automatically updates existing Dataverse connections without any downtime.
