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.

Blazing performance, excellent stability, and really nothing to dislike make Redis a must look at solution
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.
- Cache speed
- Support for high volume of transactions with elegant handling of data sets
- Ease of use - well structured and easy to implement
- Price per shard is a bit high but over all there are no issues worth mentioning
- I've heard some wishing it supported complex queries but this is asking the solution to support operations it wasn't intended for

Best open-source caching database
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.

Set up & forget
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.

Redis is THE solution to all your caching problems
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

Redis is a great product offering from Amazon
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.
- As with other service offerings from Amazon, Redis is fully managed as well and eliminates a lot of burden on our team.
- It's easy to get hold of all the metrics as it is integrated with Cloudwatch.
- Very quick and easy to deploy and configure the Redis services into our environment.
- It becomes expensive over time and need to keep a close watch on the usage.
- If the instance goes down, there is no backup preserved.

REDIS great as K/V cache
[It's being used as a] Caching service for quick key lookups.
- Quick key lookups.
- Distribution of data is easy and reliable.
- Almost HA.
- HA automatic failover for master and promoting slave on own.
- Doesn't handle 1M r/s sadly.
- Cross DC replication not so great.

Redis is awesome!
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 has many data types that suit a variety of use cases such as caching, message queues, graphs.
- Redis is an open-sourced tool with a growing community, as well as 3rd party support (Amazon managed version) if you need additional help with the set-up.
- Both the clients and the command line tool are easy to use and well-documented.
- Scaling has always been an issue with Redis. Routing to shards is not automatic.
- There's no GUI for managing the keys and values stored in Redis. The command-line tool is useful but not friendly to non-engineering users.
- The data types as in data structures have many choices, but inside of the key-value pair, the content is always stored as a string.
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.
- Great reliability and great fail over capabilities
- Easy to set up, implement and deploy
- Can scale as you grow
- Backups to AWS S3 are supported and are very easy to set up
- Better UI interface for less technical support personnel
- Wish Reids had a Chat support option
- Better documentation in a wiki format

Improve performance at a reduced cost
We use Redis in our back end messaging platform for database, cache synchronization functions. Redis is being used throughout our entire organization and is the basis for our EMR messaging platform.
- Great fail over capabilities for optimal up time
- Very easy to set up and get running
- Create backups to AWS S3
- Clustering for greater performance is very easy
- Able to scale is easy to set up and can build with your needs
- Complete data sets tend to have some difficulty. But that's mostly on the type of code you're running
- Only one module can be active at one time. Wish you could run multiple

Gets the job done!
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.
- Ease of use and set-up.
- Clustering and sharding.
- Automated backups to remote storage (S3).
- The documentation grows quite fast (200+ commands), perhaps they should have a most-used ranking.
- Redis modules (Bloom, JSON, Search) are great, but only one can be active at a time.

Redis, a fast, reliable and well supported data storage system
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.
- Atomic operations
- Quick Lookups
- Widely supported (there are many tools/libraries built over Redis)
- We had some difficulty scaling Redis without it becoming prohibitively expensive.
- Redis has very simple search capabilities, which means its not suitable for all use cases.
- Redis doesn't have good native support for storing data in object form and many libraries built over it return data as a string, meaning you need build your own serialization layer over it.

Redis is Awesome
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.
- Easy for developers to understand. Unlike Riak, which I've used in the past, it's fast without having to worry about eventual consistency.
- Reliable. With a proper multi-node configuration, it can handle failover instantly.
- Configurable. We primarily still use Memcache for caching but one of the teams uses Redis for both long-term storage and temporary expiry keys without taking on another external dependency.
- Fast. We process tens of thousands of RPS and it doesn't skip a beat.
- Autoscale. We've used Redis at RedisLabs and currently on AWS with ElastiCache plus previously I've self-hosted it and there are no real options for "serverless" or an operating model whereby I'm using only the resources needed to handle my current volume, instead, everything is provisioned and sized to your highest throughput needs. For us, that's only a few hours a day where we're at our peak, the other 16 hours could run smaller hardware but the system doesn't autoscale up/down seamlessly on any of the platform providers.
- Management console. Some systems such as Riak have a built-in GUI for ops or Mongo runs their own Compass product but Redis seems to entirely rely on other OSS solutions, which is great, but having a built-in tool that's lock-step with the released versions would ease any quick troubleshooting that CLI-challenged ops teams could utilize.
- Redis replication is asynchronous. Therefore, when a primary cluster fails over to a replica, a small amount of data might be lost due to replication lag.

Redis is a great solution for any company that wants fast development and good performance
It is used for the whole organization for caching and performance. We avoid hitting the DB in a factor of more than 100x, at a lower cost.
- Key-value access, very fast.
- Caching - either using hashmaps or simple values.
- The Python package elastic DSL is somehow incomplete.
- Moving from a Python client to Redis 2 to Redis 3 is a mess.

Super fast and easy to integrate
We currently use Redis in only one core internal application, however, this application handles around 90% of our company's internet traffic. This application load balances requests intelligently across multiple downstream server clusters. Prior to this, we used to frequently run into bottlenecks at the DB layer when web server scaling alone was insufficient.
The great thing about this is also that each cluster can be running a different version of our application allowing us to maintain a high level of robustness for our larger enterprise customers, while also allowing us to deploy frequently to other clusters that want the bleeding edge. With Redis, being able to determine the right cluster for the right request happens blazing fast.

- FAST LOOKUPS. First and foremost, this is the bread and butter of Redis. It is our go-to for any highly performant lookups.
- SCALE OUT. Helps build distributed applications that need to share data across geographies.
- Better GUI clients. At the time of adoption, the choices for UI based clients were poor. Such tools are necessary for tier 1 support personnel who may not be entirely technically savvy.

Redis Review
Redis is being used as a cache for real-time locations. It serves the last known location of users sharing their location with other users in real-time, thus being an essential part of our organization.
- Storing geolocations - Redis has built-in geolocation storage capabilities, thus saving us the time of developing the logic ourselves.
- Serving fast info for real-time apps - To anyone who works with real-time applications, fast information is the basis of good user experiences.
- I think the documentation could improve. It's not always clear, especially for engineers that are new on Redis.
- Redislabs admin interface could use a tune-up, maybe being more informative and with a better UI.
- I think the main cons I see in Redis could be that it may be a bit too obscure to new users.

Enterprise performance at a fraction of the price
We use it in our backend DB for our custom CRM platform for Healthcare providers.
- In-memory datasets.
- Computing set intersection.
- Automatic failover.
- Tech support.
- More user forums.
- A Wiki-style support page.

Redis is battle-tested
We use Redis as a distributed cache and distributed lock for our microservice environment. We have so many machines performing jobs that it's hard to make sure no task gets dropped or accidentally gets performed twice. And that's where Redis comes in--to store the global state or what jobs have been done in a fast, reliable way.
- Helpful customer support.
- Reasonable pricing.
- Keeps Redis software secure and up-to-date quietly in the background.
- Replies from customer support via could be a little faster. We're on the basic plan, and it can take up to 2 business days--it's not fast enough when your bugs need to be solved right away.
August 27, 2019
Reduced costs
Our development team uses it extensively.
- Speeds up database searches.
- Cloud-based without the need for on-prem.
- High availability.
- Support needs to be better, with chat support as an option.
- Training material for new hire dev-ops.
- Wiki-type documentation.

Redis is great when you use it correctly.
We use Redis in many capacities. We use it as a caching layer, as a shared heap, as a datastore for lock contention, as a queue, and as a primary datastore. It provides low latency storage that can be used to persist data between web requests. The data structures available allow us to use it to manage contended data in a safe and predictable fashion.
- Fast key value store
- Serializable concurrent usage (by virtue of being single-threaded)
- Wide library support
- Failover is terrifying and its safety guarantees are misleading
- Large sets (> 500k entries) have noticeable performance degradation on what is advertised to be a O(1) query pattern
- Hardware costs are high
August 12, 2019
Cache in action
We use Redis within a single group and across the enterprise.
- We used cache data to speed up the processing power.
- To do intersections of various sets and achieve a high performing solution.
- To use it as a second-level cache for large data.
- Luva script is a pain to work on
August 08, 2019
Perfect for caching and expiring data storage
We use Redis as a distributed cache for many internal tools across the entire organization. Some tool uses Redis as a filter to remove millions of duplicated jobs every day.
- Really fast.
- Data model simple to understand.
- Very simple to use.
- Support batches of operations to increase performances.
- Nothing, it just works.

Honest hands-on review of Redis
We leverage Redis as our L2 centralized cache to hold frequently accessed data such as user ids, account balances, and other metadata. It is used across our entire organization for various software services and projects. For us, the ease of spinning up an instance and having it "Just work!" is what is appealing. We don't have the luxury of hiring Redis administrators, but since our use case isn't too complex, a hosted version works just fine for us. This should speak to the flexible usability with the product.
- It's easy to manage.
- It fits most simple caching use cases.
- Can be clustered.
- Highly configurable.
- Clustering can be easier to set up.
- Sharing data can be challenging.
June 01, 2019
Things you can do with Redis
Redis has helped us to improve the performance of our database performance by using it as a buffer/cache to the most frequently accessed pieces of data while doing data analytics. It provides us with a faster and simpler way to ship data from the database to the client's computer. It also helps us work with real-time data efficiently and reliably.
- Excellent performance
- Scalability
- Reliability
- Real-time analytics
- Few commands

Redis analysis
We use it as a service. With it, we have developed libraries for rate limiting, ETL job flow coordination, and counters.
- Atomic counters
- Cache colocated with other services that require low latencies
- Automatic memory management
- CLI could be improved
- Configuration management
- Replication and snarfing

Redis: the best cache store you can get!
Redis is being used by our product engineering team. We use it for caching and as a store for our background processing engine.
- High-speed access for a database where the size is generally well-known.
- If you display real-time stock prices, you can use Redis to rapidly get the latest stock price by its key and get it displayed to the user.
- Support for data structures such as scalars, sets, hashes, and lists.
- Persistence can impact performance since Redis will use memory dump to create snapshots used for persistence.
- Redis supports only basic security options. Redis doesn't provide any access control.
- There is no internal full-text search support and it is difficult to model relationships using Redis.
