Avro Viewer FAQ
What is Avro?
Apache Avro is a data serialization system developed within the Apache Hadoop project. It uses JSON for schema definitions and a compact binary format for data, supporting schema evolution and rich data structures.
What is the difference between Avro and Parquet?
Avro is a row-based format optimized for write-heavy workloads and streaming, while Parquet is a columnar format optimized for read-heavy analytical queries. Avro is preferred for data transport and Kafka, while Parquet excels for data warehousing.
Is Avro compatible with Kafka?
Yes! Avro is the most widely used serialization format for Apache Kafka. It integrates with Confluent Schema Registry for schema management and supports forward/backward compatibility for evolving data schemas.
Does the viewer display the Avro schema?
Yes! Our viewer extracts and displays the full schema embedded in the Avro file, including field names, types, default values, and nested structures, alongside a table preview of the records.
