On the other hand, Redis’ in-memory storage makes it much better at handling massive volumes of real-time data. However, it does not scale nearly as well and has a higher barrier of entry for newer developers. Needing a change of pace, I decided to take a trip back to the MySQL versus series.
The simplest form of persistence is snapshotting, which involves periodically saving the entire Redis dataset to disk. This approach is fast and efficient, but it can result in data loss if the Redis server crashes between snapshots. If high speed and low latency are the deciding factors, then Redis is the top contender for optimum performance.
What are the benefits of NoSQL databases?
Redis is one of the only databases that supports millions of operations per second. In later chapters, we’ll cover examples that show Redis being used for both a primary and a secondary storage medium for data, supporting a variety of use cases and query patterns. You don’t want to use multiple databases in a single redis instance.
Code-wise, in-memory data structures are also much easier to implement than their on-disk counterparts. This keeps the code simple, and it contributes to Redis’ rock-solid stability. Leaderboards require constant updates and scalability across millions of users. They also require complex mathematical computation, and must be distributed globally.

Multi-threaded applications require locks or other synchronization mechanisms. In many applications, the added complexity is bug-prone and sacrifices stability, making it difficult to justify the performance gain. In the case of Redis, the single-threaded code path is easy to understand. It stores data in memory first then constantly copys the data to disk. Many use cases don’t need durability (for example I use Redis to store user sessions outside of my server program so that I can restart it without the users noticing).
I got the opportunity to use both memcached and redis together in the caching proxy that i have worked on , let me share you where exactly i have used what and reason behind same…. Normally when you execute a command to either redis or memcached, each command is a separate request/response cycle. With pipelining, redis can buffer several commands and execute them all at once, responding with all of the responses to all of your commands in a single reply.
Lessons from debugging a tricky direct memory leak
If you are on AWS, thet have different offerings for database services. Aurora would be my preferred choice given the benefits it offers, storage optimizations it comes with… Such managed services easily allow you to apply new security patches and upgrades, set up backups, replication… Doing this on your own would either be risky, inefficient, or you might just give up.
- When you’re ready to interact with MongoDB using your favorite programming language, check out the Quick Start Tutorials.
- It’s super fast too, often limited by network or memory bandwidth.
- Redis stores data in memory, and is not limited by the hard disk I / O speed when reading and writing data, so the speed is extremely fast.
- Regarding single threaded, consider that redis is designed for speed and atomicity.
- The test results include the environment parameters of the test (request quantity, client quantity, payload) and the TP value of the request time.
- However, it does have some drawbacks such as the need for additional memory and the lack of ACID compliance or support for joins.
This makes it a great choice for building complicated data structures quickly. MongoDB, however, suits most medium-sized businesses that need a reliable database. It’s relatively simple and easy to use and, as we mentioned earlier, very scalable. Overall, Redis is an excellent tool for caching web pages and reducing server load, but it also has some features that can be used to create powerful distributed applications.
MongoDB vs. Redis: Features and Benefits
Deploy your web projects to high-performance, ready-to-go cloud hosting in 3 steps. MongoDB also offers superior scalability, with an outstanding range of horizontal, vertical, and elastic options. These points make the database easily adaptable to subsequent changes, making it a better fit for startups and businesses needing to account for potential developments and growth.
However, if the current compilation environment does not have the above functions, select will be selected as an alternative. Using pipeline technology can significantly improve the read-write performance. If you don’t care about the specific data, you can directly jump to the second part to understand the reason for the excellent performance of Redis. Well in today’s world, everything is dynamic implies Data is everywhere and it’s increasing rapidly. To manage that rapid pace, we have to process it at the same pace and that is where “Redis” is our dancing floor to do freestyle fast moves with data.

This on-disk storage offers greater storage volume and less risk of system crashes. Storing data as BSON documents enables MongoDB to accommodate the many data types that normal JSON cannot parse. Additionally, it can store data redis consulting in-memory or on the cloud. I also provide options for persistence, these options allow users to save their data to disk for storage. You can also turn off persistence and use me as an efficient network data cache function.
You’ll find far better performance if you simply create a key index. The keys command is not terribly useful once you scale up since it will take significant time to return. Maybe the module was bad or our layout but it was a very simple task and it was even faster to take data with php and then stuff it into MongoDB. We’re using APC as caching-system and with that php and MongoDB. If you’re going to setup a dedicated Redis instance to be used ONLY as an LRU instance to avoid that particular scenario then there’s not really any compelling reason to use Redis over Memcached.
Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets. On the other hand, RediSQL is detailed as “A Redis module that provides a functional SQL database”. Session store is a mechanism for storing user session data in a web application. In a Redis session store, session data is stored in a Redis database, which is a fast, in-memory data structure store that can be used as a cache, database, and message broker.
