There may come a time when you want to modify an existing Iglu Central schema. The quickest and easiest way to do this is to override the schema using your pipeline Iglu.
Creating overriding schemas
To create an overriding schema, copy the Iglu Central schema and create a new Data Structure within BDP Console. The vendor, name, and version must match the Iglu Central schema you want to override.
Now you have your base reference, you can modify the properties, adjusting, adding, and removing them as needed. Once you have deployed your new schema to production, new events processed by the pipeline will utilize this schema.
