Databricks Delta Issues

Last updated: 9/15/2026

If you’re having trouble with setting up or connecting to your Databricks Delta data warehouse in Stitch, try these troubleshooting steps before reaching out to support.

Automatic schema evolution issue

The automatic schema evolution feature available for Delta tables can cause issues when loading data to your Databricks Delta destination. It is recommended to disable this option on your destination tables. For more information about this feature, see the Databricks documentation.

To avoid this issue, make sure the spark.databricks.delta.schema.autoMerge.enabled property is disabled on your table before loading data:

1. To check if this option is enabled, you can use this SQL query: SET spark.databricks.delta.schema.autoMerge.enabled;
2. If the value of this property is true, disable it using this query: SET spark.databricks.delta.schema.autoMerge.enabled=false;
