Benefits of declarative schema management
Skeema uses a declarative approach to schema management: the repository reflects a desired end-state of table definitions, and the tool figures out how to convert any database into this state. This contrasts with most preexisting schema management systems, which instead are based on a concept of migrations: an incremental series of files, each defining a schema change operation and its corresponding rollback. In this post, we’ll discuss the differences in these approaches.
