badrequest: cannot create online table is being deprecated. creating new online table is not allowed

Hello!

This seems so sudden that we cannot create online tables anymore? Is there a workaround to being able to create online tables temporarily as we need more time to move to synced tables?

Yes, the Databricks online tables (legacy) are being deprecated, and after January 15, 2026, you will no longer be able to access or create them.

https://docs.databricks.com/aws/en/machine-learning/feature-store/migrate-from-online-tables

Here are few work arounds.

1. You can create Lakebase synced tables with triggered sync, which mimics the behavior of online tables without continuous updates.
2. If you're using online tables for model serving, migrate to the Online Feature Store, which supports low-latency access and is designed for production workloads.

@nayan_wylde - Thank you - we moved to synced tables but seems to have issues that we didn't encounter in online tables, why does synced tables (or not sure if its even synced tables maybe DBR 16.4?) have a limit of 6 feature lookup tables in a feature serving endpoint? In our existing implementation with online tables (DBR 15.4) we have 7 feature look up tables and it's working fine but when we migrated to synced tables we get errors. We knew this limit because when cut some of the feature lookup tables to 6 it is proceeding without errors

Hi @hgm251 ,

There shouldn't be any sort of limit like that. Are you still encountering issues?
