Apache Drill vs ReactiveMongo: What are the differences?
Developers describe Apache Drill as "Schema-Free SQL Query Engine for Hadoop and NoSQL". Apache Drill is a distributed MPP query layer that supports SQL and alternative query languages against NoSQL and Hadoop data storage systems. It was inspired in part by Google's Dremel. 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.
Apache Drill and ReactiveMongo can be primarily classified as "Database" tools.
ReactiveMongo is an open source tool with 797 GitHub stars and 231 GitHub forks. Here's a link to ReactiveMongo's open source repository on GitHub.
