MySQL Shell 8.0

Abstract

MySQL Shell is an advanced client and code editor for MySQL. This document describes the core features of MySQL Shell. In addition to the provided SQL functionality, similar to mysql, MySQL Shell provides scripting capabilities for JavaScript and Python and includes APIs for working with MySQL. X DevAPI enables you to work with both relational and document data, see Using MySQL as a Document Store. AdminAPI enables you to work with InnoDB Cluster, InnoDB ClusterSet, and InnoDB ReplicaSet.

MySQL Shell 8.0 is highly recommended for use with MySQL Server 8.0 and 5.7. Please upgrade to MySQL Shell 8.0. If you have not yet installed MySQL Shell, download it from the download site.

For notes detailing the changes in each release, see the MySQL Shell Release Notes.
