- [Instructor] Another standout feature of Avro is its support for schema evolution. In distributed systems, where data models evolve over time, this is crucial. Schema evolution allows applications to handle data serialized with different versions of the schema without breaking compatibility. Let's dive in to see how this works, and why it's so powerful. Schema evolution allows applications to handle data serialized with different versions of the schema without breaking compatibility. Let's dive in to see how this works, and why it's so powerful. Schema evolution is the ability to modify your data model, the schema, over time while ensuring that old applications can still read new data, which is basically a backward compatibility, and new applications can still read old data, which is nothing but forward compatibility. This is especially critical in distributed systems like Kafka where producers and consumers may be using different versions of the schema, but there are few rules for…
