AVRO and JSON are both data serialization formats, but they have different characteristics that make them suitable for different use cases. Here are some benefits of AVRO over JSON:

Schema Evolution and Validation:

AVRO uses a schema to define the structure of data. This schema is included with the serialized data, allowing for strong schema evolution and validation.

JSON, on the other hand, lacks built-in support for schema evolution, making it harder to manage changes to data structures over time.

Compact Binary Format:

AVRO uses a compact binary format that reduces the size of data on disk and during transmission. This can lead to better performance and reduced network bandwidth usage compared to JSON.

Efficient Serialization and Deserialization:

AVRO's binary encoding is more efficient for serialization and deserialization compared to JSON's text-based encoding. This efficiency can result in faster data processing.

Code Generation:

AVRO schemas can be used to generate code in multiple programming languages. This makes it easier to work with serialized data and ensures type safety, reducing the chances of errors during data manipulation.

Schema Evolution Without Downtime:

AVRO's schema evolution capabilities allow you to evolve your data structures without requiring downtime or changes to both producer and consumer systems. This is crucial for maintaining compatibility in distributed systems.

Data Compression:

AVRO supports data compression during serialization, which can further reduce the size of data on disk and during transmission. This is particularly beneficial when dealing with large datasets.

Data Validation:

AVRO's schema can define data constraints, such as field types and allowed values. This helps ensure that the data adheres to the specified format, reducing the chances of errors in processing.

Strongly Typed Data:

AVRO's schema enforces data types, which can help catch data type-related issues early during development. JSON is more flexible with data types, which can sometimes lead to unexpected type-related errors.
