Apache Avro is a data serialization format. We can store data as .avro files on disk. Avro files are typically used with Spark but Spark is completely independent of Avro. Avro is a row-based format that is suitable for evolving data schemas. One benefit of using Avro is that schema and metadata travels with the data. If you have an .avro file, …

Avro provides functionality similar to systems such as Thrift, Protocol Buffers, etc. Avro differs from these systems in the following fundamental aspects.. Dynamic typing: Avro does not require that code be generated.Data is always accompanied by a schema that permits full processing of that data without code generation, static datatypes, etc.
2. Apache Avro. Avro is a language-independent serialization library. To do this Avro uses a schema which is one of the core components. It stores the schema in a file for further data processing. Avro is the best fit for Big Data processing. It's quite popular in Hadoop and Kafka world for its faster processing.
Avro is an efficient binary encoding format that allows for schema evolution, making it well suited for data processing systems. Avro uses the notion of writer schemas and reader schemas to limit the metadata needed to be encoded into payloads.
