Which database is used by Uber?

What database does Apple use?
Apple Inc. FoundationDB is a free and open-source multi-model distributed NoSQL database developed by Apple Inc. with a shared-nothing architecture.

Is Redis faster than MongoDB?
MongoDB is schemaless, which means that the database does not have a fixed data structure. This means that as the data stored in the database gets larger and larger, MongoDB is able to operate much faster than Redis. Redis is only significantly faster when the stored data is relatively small in size.
Which database does Amazon use?

The performance differences between MySQL and Postgres have been largely erased in recent versions.
Why is PostgreSQL so popular?
