Adding a schema version

When you add a schema version, you will need to compare the versions to make sure the new schema will be accepted.

To add a new version to an existing schema, use the RegisterSchemaVersion action (Python: register_schema_version) API.

Specify a SchemaId structure to indicate the schema for which you want to add a version, and a SchemaDefinition to define the schema.

Code example 12:

aws glue register-schema-version --schema-definition "{\"type\": \"record\", \"name\": \"r1\", \"fields\": [ {\"name\": \"f1\", \"type\": \"int\"}, {\"name\": \"f2\", \"type\": \"string\"} ]}" --schema-id SchemaArn="arn:aws:glue:us-east-1:901234567890:schema/registryName/testschema"
aws glue register-schema-version --schema-definition "{\"type\": \"record\", \"name\": \"r1\", \"fields\": [ {\"name\": \"f1\", \"type\": \"int\"}, {\"name\": \"f2\", \"type\": \"string\"} ]}" --schema-id SchemaName="testschema",RegistryName="testregistry"

  1. Sign in to the Amazon Web Services Management Console and open the Amazon Glue console at https://console.amazonaws.cn/glue/.

Adding a schema version.

The schema(s) version appears in the list of versions. If the version changed the compatibility mode, the version will be marked as a checkpoint.

Example of a schema version comparison

When you choose to Compare with previous version, you will see the previous and new versions displayed together. Changed information will be highlighted as follows:

  • Yellow: indicates changed information.

  • Green: indicates content added in the latest version.

  • Red: indicates content removed in the latest version.

You can also compare against earlier versions.
