Dynamic schema handling

You can choose how

Data Integration

handles changes that you make to the data object schemas. To refresh the schema every time the

mapping

task runs, you can enable dynamic schema handling in the task.

When you use Apache Iceberg tables as the Open Table format, you can configure dynamic schema handling.

The schema change includes the newly added fields within the data object.

You can configure schema change handling on the

Runtime Options

page when you configure the task.

The following table describes the schema change handling options:

Option	Description

Dynamic	Data Integration refreshes the schema every time the task runs. You can choose from the following options to refresh the schema: Alter and Apply Changes. Data Integration adds new fields from the source schema to the target schema. Don't apply DDL Changes. Data Integration does not apply the schema changes to the target.
