There are Mar 12, 2023 · Avro and JSON are both data serialization formats used in distributed computing systems, but they have several differences. Jun 9, 2025 · Choosing between Avro, JSON Schema, and Protobuf involves a trade-off between performance, flexibility, and ease of use. The test data that was serialized is around 200 bytes and I generated schema for both Avro and Protobuf. I expected some pushback, and got it: Parquet is “much” more performant. Oct 14, 2025 · This blog will delve into the performance aspects of using Avro and JSON in Kafka, exploring their core concepts, providing typical usage examples, common practices, and best practices.

Mar 18, 2024 · When comparing the use of Apache Avro and JSON for defining message schemas in an Apache Kafka environment, a fundamental distinction arises in terms of space efficiency and performance. May 16, 2023 · In my “Friends Don’t Let Friends Use JSON” post, I noted that I preferred the Avro file format to Parquet, because it was easier to write code to use it. However, for more complex systems that store larger amounts of data and have significant computational challenges, a format that supports binary encoding can yield significant advantages. I remember struggling early in my career: JSON felt modern and lightweight, but many enterprise services still used XML. Avro4K is as much as 2-3x slower in both serialization and deserialization than Jackson AVRO when unions are involved. It is easy for machines to parse and generate. 7 million times in a second where as Avro can only do 800k per second. Solution based on Avro format significantly reduces time and network traffic in communication between microservices. The Avro API uses BinaryEncoder and a ByteBuffer object to build the byte[]. Jul 4, 2016 · I am not sure if its relevant but the code that is the producer of the kafka message is in jruby. This table compares Avro and JSON data serialization formats for real-time Kafka pipelines, focusing on their performance for 500,000 messages. If you’re comparing payloads side-by-side, run them through a JSON Formatter so the structure is obvious at a glance. Jun 3, 2025 · Avro: About 3–5x faster than JSON in JavaScript and Java tests, thanks to its binary format. It uses JSON for defining data types and While JSON is a common modus operandi (especially in JavaScript), using a binary serialization format typically provides an advantage in compression size and performance at the cost of losing human readability of the encoded data. Dec 15, 2022 · Smaller size Avro stores it's data in a compact binary format, which means that any data stored in Avro will be much smaller than the same data stored in JSON.
