Avro Schemas

Avro Schemas are a way to define the structure of data used in applications, particularly in big data and messaging systems. Think of a schema as a blueprint that specifies what types of data fields are present (like names, ages, or addresses) and their formats (like text or numbers). This ensures that data is consistent and can be understood by different systems, allowing them to exchange information smoothly. Avro Schemas also support versioning, meaning that as data evolves, older systems can still understand newer data formats.
