java.lang.Object

liquibase.integration.spring.SpringLiquibase

All Implemented Interfaces:

public class AsyncSpringLiquibase
extends liquibase.integration.spring.SpringLiquibase

Specific liquibase.integration.spring.SpringLiquibase that will update the database asynchronously.

By default, this asynchronous version only works when using the "dev" profile.

The standard liquibase.integration.spring.SpringLiquibase starts Liquibase in the current thread:

• This is needed if you want to do some database requests at startup
• This ensure that the database is ready when the application starts

But as this is a rather slow process, we use this asynchronous version to speed up our start-up time:

• On a recent MacBook Pro, start-up time is down from 14 seconds to 8 seconds
• In production, this can help your application run on platforms like Heroku, where it must start/restart very quickly
