| Special Characteristics | Redis is ranked as world?s fastest database. It reduces application complexity, simplifies development, accelerates time to market and provides unprecedented flexibility to developers with its visionary data structures and modules. | MongoDB is considered as the next-generation database. It successfully helped many businesses to transform their industries by providing big data. The world?s most sophisticated organizations, from cutting-edge startups to the largest companies, use MongoDB to create applications never before possible, at a very low cost. |
| Comparing Advantages | Redis is an in-memory database platform provides support of wide range of data structures such as strings, hashes, sets, lists, sorted sets, bitmaps, hyperloglogs, and geospatial indexes. Redis provides effortless scaling in a fully automated manner by overseeing all the operations of sharding, re-sharding, migration. It also includes persistence, instant automatic failure detection, backup and recovery, and in-memory replication across racks, zones, datacenters, regions, and cloud platforms. |
MongoDB provides the best of traditional databases as well as flexibility, scale, and performance required by today?s applications. MongoDB is a database of giant ideas. MongoDB keeps the most valuable features of Relational database i.e. strong consistency, expressive query language and secondary indexes. It facilitates developers to build highly functional applications faster than NoSQL databases. |
