Skeema is a tool for managing MySQL and MariaDB schema changes in a declarative fashion using pure SQL. The Skeema CLI tool allows you to:

• Export CREATE TABLE statements to the filesystem, for tracking in a Git repo
• Diff changes in the schema repo against live DBs to automatically generate DDL
• Manage multiple environments (e.g. dev, staging, prod) and keep them in sync with ease
• Configure use of online schema change tools, such as pt-online-schema-change, gh-ost, or spirit, for performing ALTER TABLE
• Apply configurable linter rules to proactively catch schema design problems and enforce company policies

Skeema supports a pull-request-based workflow for schema change submission, review, and execution. This permits your team to manage schema changes in exactly the same way as you manage code changes.
