title: MySQL - How do I automatically manage updates on multiple databases?
body: <p>For my MySQL application I am required to have every client on the their own database i.e. the database is NOT multi-tenant. Therefore, I have many copies of the same MySQL database schema on multiple servers.</p>
  
  <p>How do I automate the propagation of SQL DDL, such as ALTER TABLE, CREATE TABLE, DROP TABLE, CREATE INDEX etc. across multiple databases on multiple servers?</p>
  
  <p>I may have more than 300 databases in the next few months on 4 or more servers.</p>
