X DevAPI User Guide  /  Overview

Pre-General Availability Draft: 2017-12-04

Chapter 1 Overview

This guide explains how to use the X DevAPI and provides examples of its functionality. The X DevAPI is implemented by MySQL Shell and MySQL Connectors that support X Protocol. For more background information and instructions on how to install and get started using X DevAPI, see Using MySQL as a Document Store. For quick-start tutorials introducing you to X DevAPI, see Quick-Start Guide: MySQL Shell for JavaScript and Quick-Start Guide: MySQL Shell for Python.

This section introduces the X DevAPI and provides an overview of the features available when using it to develop applications.

Important

The X DevAPI implementation in MySQL Shell can differ from the implementation in the Connector products. This guide provides an overview of using the concepts in all X DevAPI implementations. Consult Additional Documentation for the X DevAPI reference documentation for the implementation you are using to verify exact syntax and usage.

The X DevAPI wraps powerful concepts in a simple API.

  • A new high-level session concept enables you to write code that can transparently scale from single MySQL Server to a multiple server environment. See Chapter 2, Connection and Session Concepts.

  • Read operations are simple and easy to understand.

  • Non-blocking, asynchronous calls follow common host language patterns.

The X DevAPI introduces a new, modern and easy-to-learn way to work with your data.

Additional Documentation

In addition to this guide, which provides examples in many languages, a comprehensive reference manual is available for each language which implements the X DevAPI.

For general information about using MySQL Shell, which provides JavaScript and Python implementations of X DevAPI, see MySQL Shell User Guide.

Note

The MySQL Shell JavaScript and Python code examples used through this document are specific to MySQL Shell and rely mostly on the exception handling done by MySQL Shell. For all other languages proper exception handling is required to catch errors. For more information see Section 8.2, “Error Handling”. Similarly, in MySQL Shell there is no need to import the X DevAPI related library, it is imported automatically. Other languages need to import the library.
