can be set using `liquibase.change-log`. In addition to YAML, Liquibase also supports
JSON, XML, and SQL change log formats.
By default Liquibase will autowire the (`@Primary`) `DataSource` in your context and use
that for migrations. If you like to use a different `DataSource` you can create one and
mark its `@Bean` as `@LiquibaseDataSource` - if you do that remember to create another one
and mark it as `@Primary` if you want two data sources. Or you can use Liquibase's native
`DataSource` by setting `liquibase.[url,user,password]` in external properties.
See
{sc-spring-boot-autoconfigure}/liquibase/LiquibaseProperties.{sc-ext}[`LiquibaseProperties`]
for details of available settings like contexts, default schema etc.
