Avro is an open source project that provides data serialization and data exchange services for Apache Hadoop. These services can be used together or independently. Avro facilitates the exchange of big data between programs written in any language.

When should I use Apache Avro?

Apache Avro is especially useful while dealing with big data. It offers data serialization in binary as well as JSON format which can be used as per the use case. The Avro serialization process is faster, and it’s space efficient as well.

What is Avro good for?

Avro is an open source data serialization system that helps with data exchange between systems, programming languages, and processing frameworks. Avro helps define a binary format for your data, as well as map it to the programming language of your choice.

How does Apache Avro work?

Avro has a schema-based system. A language-independent schema is associated with its read and write operations. Avro serializes the data which has a built-in schema. Avro serializes the data into a compact binary format, which can be deserialized by any application.

Avro Uses: When to Use Avro

  1. By using Avro we are able to read the data from disk with applications written in other languages besides Java or the JVM.
  2. Also, Avro allows us to transfer data across a remote system without any overhead of java serialization.

What is the difference between Avro and JSON?

Avro can be classified as a tool in the “Serialization Frameworks” category, while JSON is grouped under “Languages”. Redsift, OTTLabs, and Mon Style are some of the popular companies that use JSON, whereas Avro is used by Liferay, LendUp, and BetterCloud.

What is difference between Avro and Parquet?

Avro is fast in retrieval, Parquet is much faster. parquet stores data on disk in a hybrid manner. It does a horizontal partition of the data and stores each partition it in a columnar way.

How is data stored in Avro?

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. Avro files include markers that can be used to split large data sets into subsets suitable for Apache MapReduce processing.

Does Kafka use Avro?

In the Kafka world, Apache Avro is by far the most used serialization protocol. Avro is a data serialization system. Combined with Kafka, it provides schema-based, robust, and fast binary serialization.
