Apache AVRO Data Format

This page details information about using the Apache AVRO data format and integration with the Kafka Schema Registry.


Apache AVRO was added as an inbound data format in Cinchy v5.3.

Apache AVRO (inbound) is a data format with added integration with the Kafka Schema Registry, which helps enforce data governance within a Kafka architecture.

Avro is an open source data serialization system that helps with data exchange between systems, programming languages, and processing frameworks. Avro stores both the data definition and the data together in one message or file. Avro stores the data definition in JSON format making it easy to read and interpret; the data itself is stored in binary format making it compact and efficient.

Some of the benefits for using AVRO as a data format are:

  • It is compact

  • It has a direct mapping to/from JSON

  • It's fast

  • It has bindings for a wide variety of programming languages.
