Product Details

What is Redis™*?

According to the vendor, Redis is an in-memory multi-model database that supports multiple data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs and geospatial indexes with radius queries. Redis has built-in replication, Lua scripting, LRU eviction, transactions and different levels of on-disk persistence, and provides high availability and automatic partitioning with Redis Cluster.

Redis combines in-memory, schema-less design with optimized data structures and versatile modules that adapt to your data needs. The result is an adept, high performance, multi-purpose database that scales easily like a simple key/value data store but delivers sophisticated functionality with great simplicity, according to the vendor.

Redis also enables data persistence and high availability through replication and backups. Redis Enterprise is built from the ground up to serve as a system of record for any application.

Redis has proven itself to be an invaluable tool in a wide range of use cases. Users have found Redis to be exceptional as an efficient caching solution, allowing for the distribution of data and storage of web sessions. This capability has led to significant improvements in performance and reliability, making it a go-to choice for many backend development teams. Additionally, Redis's versatility as a NoSQL key-based database store has made it a preferred option for organizations working alongside other databases like PostgreSQL and Memcache. Its ease of use, stability, and reliability have made it a popular choice across multiple departments within organizations.

Furthermore, Redis has been leveraged in various R&D projects to experiment with its implementation in different modules. Starting with cache management, users have been able to extend its usage to address specific project needs effectively. In these experiments, Redis has served as a traditional in-memory key store warehouse for cache systems with a vast number of items, resulting in substantial latency savings. Its ability to manage distributed queues efficiently has also made Redis an excellent choice for tasks that require multiple worker nodes to subscribe and complete tasks. The flexibility Redis offers by enabling users to store sets of object-based information and lists further improves performance through set operations.

In addition to these use cases, Redis has become synonymous with simplicity and speed when it comes to basic yet fast key-value storage solutions. It has been extensively adopted in organizations, including game studios, where it is used for storing user data, session data, game data, and indexing information. For example, Redis Enterprise has been utilized to support backend systems for casual games by providing sub-millisecond response times and facilitating clustering, sharding, backups, and monitoring.

Moreover, customers have found Redis instrumental in addressing various challenges such as big data processing, handling temporal data, managing session state, and even as a caching service in microservices environments. Its ability to provide data consistency, concurrency management, and high-speed operations has proven invaluable. Additionally, Redis has been a reliable tool for caching solutions in e-commerce storefronts and data visualization applications. Users have reported reduced server load and improved performance as a result of implementing Redis as a cache.

Redis has also found success as a buffer cache, allowing for faster data retrieval and improved overall database performance. Its role in processing queues, calling APIs, and supporting vital organizational workflows has been recognized by customers who rely on its stability and speed. Furthermore, users have implemented Redis across various domains to manage user timelines, build notification systems, and implement microservices architecture

Users recommend the following for Redis:

Consider other cache options before choosing Redis. It is advisable to try out other caching solutions before jumping to Redis, even though it is a great tool for highly distributed caching.

Understand the purpose of Redis in your implementation. It is important to have a clear understanding of how Redis will be used in your specific application. Don't assume that it will work straight out of the box. Evaluate data structures and choose a model that allows for faster query times.

Use Redis for specific use cases. Redis shines in certain areas such as synchronizing states across instances and handling user sessions with Node.js. It can also be a good alternative for relational data when speed is of utmost importance. However, users caution against abusing Redis and recommend using it in a reasonable way.

Overall, users believe that Redis is a valuable tool for fast reliable storage and caching, particularly for enterprise applications. However, they also advise considering other key-value stores depending on the specific use case at hand.

Redis is being leveraged to address big data, temporal data and session state challenges across the software stack. New opportunities to leverage it are continually being investigated and identified. It addresses data consistency and concurrency issues and provides amazing speed to what could be slower operations if handled without it.

Redis is used as cache storage in our data visualization application where response time is key. We use Redis for some of the flag features in a system with more than 20,000 internal users. This in-memory database helped to solve many of the use cases we've had on our product like user based caching, realtime analytical operations on one time fetched results.

We use it to manage & control user sessions in a Tomcat based web application programmed with Java. It's used in both production and testing & development environments in this certain application's server backend, but only the software development department actually understands & manages it. It solves the case to keep users logged in to the application and also invalidates the sessions when requested or automatically if they expire.

Redis was used in a project to merge live data from different sources. Then by using Lua scripting we were able to make some further aggregations and data binding for better results. It was essential for us as preparation for next steps.
We also used it as session storage manager for some other projects.

Our organization uses data a lot. It is essential that we deal with a huge set of data and in a quick and timely fashion. Our data services in order to achieve this, we use Amazon's Redis cache. It's been working great for us and we have been using Redis for 1.5 years now. It is reliable and helps speed up our services by at least 40% and reduces the DB calls.

We used Redis for application data caching. Redis is used by more than one department and is an enterprise standard offering. We have since moved away from Redis as we were able to simplify our architecture given our more powerful database servers after our latest tech refresh. When we were using Redis, our application response times were too slow for certain transactions so we cached the data to improve performance. There are other use cases that we considered like caching of session data. Again our goal was to simplify our architecture and Redis was one of the products we eliminated, not because it wasn't a good product but because we no longer needed it for our application.

Redis is used across all the organization. It is used by our main games to store user data, session data, game data, and indexing some information related to it.

Having backend systems that support casual games, like Trivia Crack, must support instant virtualization and big spikes that can happen during holidays, Christmas, and so on. Consequently, it is important to have a sub-millisecond database to be able to increase the requests rate very rapidly.

We're using Redis in many ways and across different departments in the organization. The most simple use case is to store locks so the backend services can reject duplicated API requests. A little more advanced use case is to use it as a buffer for queues of messages or requests. We're also exploring ways to use the new Graph type to support Data Science models in development.

Redis is being used as our main nonSQL database store. We run PostgreSQL as the main relational data store, Our entire platform used within the business unit utilizes Redis and is also customer facing. The stability, reliability and scalability are great and it's also easy to easy to set up and implement.

Redis Enterprise helps us by making clustering, sharding, backups and some more very easy to set-up, control, and monitor. It's quite nice being able to sleep at night knowing that despite all your database is on volatile memory (RAM) or a hybrid solution (Redis on Flash), and still have the information clustered, sharded, replicated, and constantly being backed up, with just a few clicks. The support is really great, and the ease of use and set-up are also big selling points.

We're currently using Redis to support distributed caching and synchronization across our app. Our application runs on multiple servers so ensuring all infrastructure is in sync and key operations are atomic is critical. It's being used by the backend development team in core infrastructure. Redis is well suited to solve this problem as it offers both performance and reliability.

Redis is being used as our primary NoSQL key-based database store. In the specific platform that Redis is being used the most, we have PostgreSQL as the main relational data store, Memcache for expiring key-based caching and Redis. The entire platform used within the business unit utilizes Redis but other departments are starting to use it as well given the ease of use, stability, and reliability.

Redis is used by our organization to deliver schedules to the users of livestreams and playlists. We needed something that could deliver very high requests per second and also allow us database updates without impact to our customers. This has been accomplished with Redis.

We use Redis as a Cache DB in a microservices environment to store auth tokens, temporary data and sync flags to coordinate processes that are handled by multiple parties asynchronously.
The main problem it solves for us is to need to have a high-performance cache that also provides data persistence so we can restart instances and deploy new ones without losing data in the middle. This is very important for us because of the problem we're tackling. In the case of auth tokens, we don't want to make all users log in again after we restart an instance because the memory got cleared. The same applies for the sync flags that our processes depend on to complete.

We use Redis to run frontend caching, sessions and backend value store systems for our main web property. We are big supporters of the community and love watching it evolve over time. We've been early adopters in the NoSQL movement starting with Mongo and Couch. We're still using Redis, although we can't say the same for the others.
