1. Redis :
In memory data structure project implementing a distributed in-memory key-value database with optional durability, Redis stands for Remote Dictionary Server.
On May 10, 2009, Redis was first released by Redis labs.
It is written in both ANSI and C. “
There are a number of advantages to using Redis, such as its memory efficiency, speed, and high availability.
2. MongoDB :
As a cross-platform, document-oriented, and non relational (i.e. NoSQL) database, MongoDB is a must-have tool.
Data are stored in the form of a key-value pair in an open source database.
On February 11, 2009, MongoDB was released by MongoDB Inc.
MongoDB is a high-performance, high-availability, and high-scalability database that is easy to use.
Difference between Redis and MongoDB :
|Initiated by Redis labs, it was first made available to the public on May 10, 2009.||On February 11, 2009, MongoDB Inc. published the first version of the database.|
|Key-Value Store is Redis’ primary database model.||Document Store is the primary database model for MongoDB.|
|Strings, hashes, lists, sets, and sorted sets, as well as bit arrays, hyperloglogs, and geospatial indexes, are all supported data types in the Redis data store.|
As a result, there are only partial predefined data types.
|All of the supported data types in MongoDB can be accessed using a single .command:’mongodb’.|
As a result, you should have predefined data types in place.
|The RediSearch module is the only one that supports secondary indexes in Redis.||Using supplementary indexes in MongoDB is completely unrestricted.|
|Master-Slave Replication and Master-Master Replication are supported by Redis.||In MongoDB, Master-Slave Replication is only supported.|
|Map Reduce is not supported by Redis.||Map Reduce is supported by MongoDB.|
|BDS, Linux, OS X, and Windows are all options for running Redis on a server.||Solaris, Linux, OS X, and Windows are the supported operating systems for MongoDB servers.|
|Companies like Twinkl, Merrill Corporation, ASOS.com Limited, Owler.com, etc. use Redis as a backend database management system.||In addition to Adobe and Amadeus and Lyft and ViaVarejo and Craftbase, a number of other companies use MongoDB.|
