Avrohan

Avrohan refers to a family of open-source data serialization systems developed by Apache. Its primary function is to provide a flexible and efficient way to store and transmit structured data. Avro is known for its schema-based approach, meaning that data is described by a schema, which can be written in JSON format. This schema defines the data's structure, data types, and other constraints.

One of the key features of Avro is its schema evolution capabilities. This allows for changes to be made to the data's schema over time without breaking compatibility with older or newer versions of the data. This is achieved by specifying rules for how schemas can evolve, such as adding or removing fields, or changing data types. Avro supports two types of schemas: a writer's schema and a reader's schema. The writer's schema is used when data is serialized, and the reader's schema is used when data is deserialized. During deserialization, Avro uses both schemas to resolve any differences and ensure data can be read correctly.

Avro is widely used in big data ecosystems, particularly with Apache Hadoop and Apache Kafka. Its compact binary format and schema evolution make it suitable for large-scale data processing and storage. It can be used for various purposes, including data warehousing, stream processing, and inter-process communication. The system offers APIs for several programming languages, facilitating its integration into diverse applications.
