Customer Insight Data Ingestion with Delta Table

Posted on by ROHITHGMURALI

Hello,

I am currently trying to do an ingestion from a non-databricks datastore to customer insights by programmatically converting my data into Delta Table format. I see that, whenever I deal with a timestamp column, the table in customer insight gets errored out. I found suggestions to set minReader version to <= 2, however I find it very unstable when dealing with timestamp column. Is there any solution, so that I can Ingest my data with timestamp into Customer Insights Table using Delta Table format?

Yes, Customer Insights has limited support for Delta Lake features. Timestamp columns can cause ingestion failures if the Delta table uses newer protocol versions or unsupported features.

Recommended approach:

Keep minReaderVersion <= 2.

Avoid advanced Delta features (column mapping, deletion vectors, etc.).

If issues continue, store timestamps as ISO 8601 strings and convert them after ingestion.

If you share the exact error and how you're generating the Delta table, the root cause can be identified more precisely.
