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 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.
  • A modern key-value store in-memory database.
  • Redis [is thorough] and details user documentation.
  • Data distribution on a multi-tenant cluster is easy and reliable.
  • It lacks support for datatypes that are available on other products.
  • Making it work with Celery is a bit hard and sometime it's not reliable.
  • Lacks better UI like other systems.
Redis has been a great investment for our organization as we needed a solution for high speed data caching.
The ramp up and integration was quite easy.
Redis handles automatic failover internally, so no crashes provides high availability.
On the fly scaling scale to more/less cores and memory as and when needed.

  • Redis is easily one of the best open source in-memory database to invest in.
  • Redis is best for caching, easy to set up, and it's easy for anyone use with the help of its great documentation.
  • The distributed cache makes it even faster when using multiple data-centers across continents.
UI isn't that great compared to the other competitors.
The management of our memcached cluster was becoming pretty complicated as the application grew in size. Redis is a much better option compared to memcached.
Redis is bit unreliable compared to the alternative RabbitMQ especially when it needs to be integrated with Celery.
It's pretty easy to start with Redis. Redis allows you to deploy an extremely fast production-grade clustered in-memory datastore that can be used as a cache layer or for any other fast data access needs. Redis Enterprise provides a managed solution which is deployed on memory-optimized instances for the best performance. Since this is an enterprise solution, the support provided for a given cluster is exemplary.
Redis enterprise solution has good support.

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.
  • Has been working well for storing user sessions.
  • No need for maintenance operations. Once it's set up has been working flawlessly.
  • Many configuration options, little programming required.
  • The actual database structure is difficult to understand.
  • Only command line application available for free. Difficult to use.
  • Seems to have some encoding issues when inspecting data directly with CLI app.
It is well suited when a web application needs to store any kind of user sessions. It works both for storing logged in user sessions but also for non authenticated users. User sessions are temporary; however, for storing permanent data that needs to be retained across sessions it is not appropriate because Redis is an in-memory database.

  • Free to use and easy to integrate with other technologies. Doesn't take much development days.
  • Has not required any support from developers after initial implementation.
It is quite simple to set up for the purpose of managing user sessions in the backend. It can be easily integrated with other products or technologies, such as Spring in Java. If you need to actually display the data stored in Redis in your application this is a bit difficult to understand initially but is possible.
I have not needed to contact support team and have managed to implement use cases with freely available information online.

Redis is used as our primary cache for our application to help reduce response time and improve user experience. By caching read intensive data in Redis, this also helps to reduce load on our database.
  • Great performance for reading data
  • Easy to set up and work with
  • Great support for many different types of data structure
  • Lacking monitoring and administration tools
  • System resource consumption as you scale up
Perfect solution for caching needs. If you have a bottleneck due to frequent data access to your database, then Redis can really help you by diverting those traffic away from your database. Its key/value pair structure also makes data lookup very efficient, providing excellent performance.

  • Significantly improved response time of our application
  • Greatly improved user experience by making the application more responsive
  • Reduce cost on database systems
Very easy to set up. My team got everything up and running in a matter of hours, and was able to start focusing developing our application right away.
There are tons of documentation from both Redis themselves as well as online communities. Many cloud vendors such as IBM Cloud also have expertise in-house to provide support.

Redis is used for transnational processing and scoring of customer data models for pub/sub-distribution to other models of data.
  • Redis provides the ability to score data quickly.
  • Redis provides the ability to distribute this info in a fast manner.
  • Redis provides an alternative method for data retrieval which lessens the load on the database access.
  • Greater emphasis on Pub/Sub capabilities more in line with Kafka.
Well suited for keeping track of scoring scenarios.

Poorly suited for long term storage of data.

We use redis and recommend for our clients. The key areas Redis outsteps all others are:
1) Scalability
2) Unique and flexible key value db structure
3) They use Ssd Flash for their instances

They also provide session management capabilities to be implemented in any huge projects without much headache. Their db instance also provides a high number of read write per second, which makes it a leader.
  • Session Management
  • Key value pair DB structure
  • High scalability
  • Flash instances
  • Failover Replicas
  • Data Consistency
Redis is particularly suited when you want to mesh millions of data and get a unique statistics or a child dataset out of it. Then Redis is the only viable product with the highest number of read and write per second. It increases my speed drastically so that I am able to put 10k records per second and successfully retrieve at same speed.
  • It increased my speed of meshing.
  • It increased my user experience by stream-less rendering.
  • It created huge impact in my metasearch, my basic income has increased by 120% in last 45 days.
Redis was initially in the list of competitors like Aerospike, Cassandra, MongoDB.The major point that outset all others is that it provides a number of read and writes to the database that no one can match. Another major factor is Redis really knows the basic components that we need these days, e.g. we can take mpas for geolocation, and they provide a rich set of datatypes that becomes handy.
