Liquibase vs Objectify: What are the differences?

Liquibase: Source control for your database. Liquibase is a leading open-source tool for database schema change management. Liquibase helps teams track, version, and deploy database schema and logic changes so they can automate their database code process with their app code process; Objectify: Java data access API specifically designed for the Google Cloud Datastore. It is a Java data access API specifically designed for the Google Cloud Datastore. It occupies a "middle ground"; easier to use and more transparent than JDO or JPA, but significantly more convenient than the low-level API libraries that Google provides. Objectify is designed to make novices immediately productive yet also expose the full power of the Datastore.

Liquibase and Objectify can be categorized as "Database" tools.

Some of the features offered by Liquibase are:

• Supports code branching and merging
• Supports multiple developers
• Supports multiple database types

On the other hand, Objectify provides the following key features:

• Lets you persist, retrieve, delete, and query your own typed objects
• Surfaces all native datastore features, including batch operations, queries, transactions, asynchronous operations, and partial indexes
• Provides type-safe key and query classes using Java generics

Liquibase and Objectify are both open source tools. It seems that Liquibase with 1.91K GitHub stars and 1.15K forks on GitHub has more adoption than Objectify with 676 GitHub stars and 149 GitHub forks.
