Liqiubase
provides Change Types tagDatabase that let's mark the current database
state
, version
, release
, and other information by versioning
the current state of the database
by applying a tag
. Liquiase
will insert a new record in DATABASECHANGELOG
table with the tag
name specified in ChangeSet
.
Tags
allows Liquibase
to rollback database
to the tag status
. Liquibase
provides tag
command in CLI
to tag
current status without creating ChangeSet
.
