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 Solves many application caching problems.
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.
- Application data caching.
- Session data caching.
- Managing cache misses better.

Best DB for a gaming company willing to scale overnight
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.
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.
- Answer requests at sub-millisecond latency: by having all the data in memory, the latency has no comparison to other disk based DBs.
- Simplicity: it is incredibly simple and straightforward to use. You can download Redis and start using it during the next five minutes.
- Reliable & scalable: when working with a cluster (and if you have a proper sharding strategy), your DB can scale to pretty high numbers and not to die in the middle of any spike.
- Cost: by having all the data in memory, it can be very expensive. There should be an option for having some data stored on disk, at least initially (and with the tradeoff of some higher latency).
- Lack of some basic permissions: there should be a way of having a user with restricted commands (i.e.: no keys *, now write commands, etc).
- Multi-module available on the same Redis instance (as far as I know, this is not possible yet).

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.

If you need lots of user sessions, this is the product to use
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.
- The system is very reliable. The only times we had issues was when we hit database capacity limits.
- There is continuing development on the technology (like Redis streams) that make it an even more attractive technology.
- For systems that require many concurrent users, like several million watching the Super Bowl on their connected devices, it works and it works well.
- None that I can think of

Get a cache server on steroids with Redis and get rid of those Memcached instances
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.

- High performance. Redis is FAST, really fast.
- Data persistence. Having this feature was the main reason we chose Redis over Memcached.
- Clustering. Distributing data between multiple instances is easy to do with Redis.
- Data types. It isn't normal to have native data types supported on cache servers, but Redis covers many areas for this use case.
- The data type collections aren't extensive and can fall short for some needs.
- Single-threaded. Redis doesn't support multi-threading, so it won't benefit from multi-core CPUs. Instead, you need to deploy several single-core instances to scale horizontally. While this is a design decision, it may be a downside on some infrastructures.
- Lack of UI. A visual UI can be a downer for some users.

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.

Fan Redis user
We used Redis mainly to cache the database and as a message broker to avoid the hard work on the main server. It's used by our IT department, it's our first choice when we need a broker for messaging or cache data without persistence.
- Cache layer
- Transport layer
- Store data with expiration time
- None, it's perfect for us.

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
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

Redis is the backbone of our ephemeral data, from web page caching to session storage.
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.
- Key value storage
- Session and Cookie management
- Frontend caching
- Third-party library support sometimes lags
- Weak type support
- Everything is in memory, so you need lots of RAM

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.

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

The Redis Imperative
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.

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.

Simple yet powerful datastore
We use it as one of our app supporting platforms (Resque & Rails).
- Simple, fast Keystore.
- Reliable.
- Efficient storage.
- Better handling if capacity is reached - sometimes it just crashes our server.

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.

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
