Image from wikipedia.orgThrift is a lightweight, language-independent software stack with anassociated code generation mechanism for RPC. Thrift provides cleanabstractions for data transport, data serialization, and applicationlevel processing. Thrift was originally developed by Facebook and now it is open sourced as an Apache project.Apache Thrift is a set of code-generation tools that allows developers to build RPC clients andservers by just defining the data types and service interfaces in a simple definition file. Giventhis file as an input, code is generated to build RPC clients and servers that communicateseamlessly across programming languages.In this tutorial I will describe how Thrift works andprovide a guide for build and installation steps, how to write thrift files and how to generate fromthose files the source code that can be used from different client libraries to communicate withthe server.
Thrift supports a variety of languages including C, Java, Python, PHP, Ruby butfor simplicity I will focus this tutorial on examples that include Java and Python.
Apache Avro is a popular data serialization system that relies on schemas. The official Avro documentation can be found here:.This post walks through an example of serializing and deserializing data using Avro in Java. Maven is not necessary for working with Avro in Java, but we will be using Maven in this post.Step 1 – Update pom.xmlAdd the text below (versions might need updating) to your Maven pom.xml file. This lower section will allow us to use the convenience of code generation (discussed below).

Step 3 – Compile your projectBy compiling your project, you will trigger code generation. Code generation allows us to automatically create classes to work with BdPerson schema objects (from the previous step). After compiling, the BdPerson class will appear in our com.bigdatums.avro package (defined in schema). There are various ways to compile the project, including running mvn compile from the command line in the project directory.Step 4 – Create Schema ObjectsUse the classes in the newly generated BdPerson class to create schema objects. 2 thoughts on “Simple Apache Avro Example using Java”.
TristanPlease add absolute paths for the files you mention. Why is does the avro schema file need to be within the outputDirectory? It seems like the avro schema would be the source of what the code generation would be based on, so its confusing that its considered an output. Or am I reading into this wrongly? Isn’t the output the generated code?

And the input is the schema? Some absolute paths in for every file you mention would really clear this up for me.
