Apache Avro is an open-source, language-neutral data serialization format widely used for:

• Reliable data exchange: Enables efficient and reliable exchange of data between different systems and applications, regardless of programming language.

• Data storage: Stores structured data efficiently, particularly in distributed systems and big data processing pipelines.

• Schema evolution: Supports flexible schema evolution, allowing data structures to change over time without breaking compatibility with existing systems.

Key Features:

• Schema-based: Uses a JSON-like schema to define the structure of data, ensuring data integrity and interoperability.

• Binary encoding: Encodes data efficiently in a binary format, resulting in smaller file sizes compared to human-readable formats like JSON.

• Language-neutral: Works with various programming languages, offering cross-language communication capabilities.

• Rich data types: Supports diverse data types, including primitives, arrays, maps, unions, and record structures.

• Schema evolution: Allows updating schemas without data loss or breaking existing applications.

Benefits of Using Avro:

• Efficiency: Smaller data size than text-based formats like JSON, improving storage and transmission efficiency.

• Flexibility: Easily adaptable to evolving data structures due to schema evolution capabilities.

• Reliability: Enforces data integrity and consistency through schema validation.

• Interoperability: Seamless data exchange between various systems and languages.

• Performance: Optimized for high-performance data processing in big data pipelines.
