I’m looking at liquibase as means to transform my sql schema/data during a migration.
It would be handy if liquibase allowed the database change set to be a database itself, performing changeset operations on the changesets 
This would allow a changeset to be modified before application to a db migration/update.
Another useful feature that I’m looking for seems missing: the ability to only grab data from specific tables.
Is this in any way possible right now? Or is this some wishing thinking?
