Massive vs ReactiveMongo: What are the differences?
Developers describe Massive as "A Postgres-Centric Data Access Tool". Massive's goal is to help you get data from your database. This is not an ORM, it's a bit more than a query tool - our goal is to do just enough, then get out of your way. Massive embraces SQL completely, and helps you out when you don't feel like writing another mundane select * from statement. On the other hand, ReactiveMongo is detailed as "Non-blocking, Reactive MongoDB Driver for Scala". ReactiveMongo is designed to avoid any kind of blocking request. Every operation returns immediately, freeing the running thread and resuming execution when it is over. Accessing the database is not a bottleneck anymore.
Massive and ReactiveMongo can be categorized as "Database" tools.
Massive and ReactiveMongo are both open source tools. Massive with 2.55K GitHub stars and 194 forks on GitHub appears to be more popular than ReactiveMongo with 797 GitHub stars and 231 GitHub forks.
