How do I use Apache Avro for data serialization?

Apache Avro is a framework for data serialization that provides a compact binary format. You can use it by defining a schema in JSON format, which describes the structure of your data.

Can you show me an example of an Avro schema?

Sure! Here's a simple example of an Avro schema for a user record:

{
  "type": "record",
  "name": "User",
  "fields": [
    {"name": "name", "type": "string"},
    {"name": "age", "type": "int"},
    {"name": "email", "type": "string"}
  ]
}

How do I serialize data using this schema?

To serialize data, you can use the Avro library in your programming language of choice. For example, in Python, you would use the fastavro library to write data to a file using the schema.

What are the benefits of using Avro over other serialization formats?

Avro offers several benefits, including a compact binary format, schema evolution support, and easy integration with big data tools like Apache Hadoop.
