What is Redis?
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.
What is VoltDB?
VoltDB is a fundamental redesign of the RDBMS that provides unparalleled performance and scalability on bare-metal, virtualized and cloud infrastructures. VoltDB is a modern in-memory architecture that supports both SQL + Java with data durability and fault tolerance.

What are some alternatives to Redis and VoltDB?
Good for a cluster, much slower than EhCache
February 17, 2017 18:25
Redis is a good caching tool for a cluster, but our application had performance issues while using Aws Elasticache Redis since some page had 3000 cache hits per a page load and Redis just couldn't quickly process them all in once + latency and object deseialization time - page load took 8-9 seconds. We create a custom hybrid caching based on Redis and EhCache which worked great for our goals. Check it out on github, it's called HybriCache - https://github.com/batir-akhmerov/hybricache.
Trello uses Redis
Trello uses Redis for ephemeral data that needs to be shared between server processes but not persisted to disk. Things like the activity level of a session or a temporary OpenID key are stored in Redis, and the application is built to recover gracefully if any of these (or all of them) are lost. We run with allkeys-lru enabled and about five times as much space as its actual working set needs, so Redis automatically discards data that hasn’t been accessed lately, and reconstructs it when necessary.
Stack Exchange uses Redis
The UI has message inbox that is sent a message when you get a new badge, receive a message, significant event, etc. Done using WebSockets and is powered by redis. Redis has 2 slaves, SQL has 2 replicas, tag engine has 3 nodes, elastic has 3 nodes - any other service has high availability as well (and exists in both data centers).
Performance Assessment Network (PAN) uses Redis
Slowly migrating from ASP .Net state service to Redis
blueprintmrk uses Redis
Replaced memcache and alleviated lots of issues on the spot absolutely amazing caching, with memory-based storage it's a win-win.
Runbook uses Redis
Used as a cache for monitors and reactions, can be used when RethinkDB is having issues.
nrise uses Redis
memcached 와 비슷한 퍼포먼스를 내면서 persistence 지원을 통해 in-memory cache 의 단점을 충분히 극복합니다. 메인 캐시서버로 사용하고 있습니다.
Kalibrr uses Redis
We use Redis as a key-value store, a cache, and a message queue. It's a ridiculously fast and simple-to-maintain jack-of-all-trades.
DeliciousDB uses Redis
We also have support for Redis databases so that developers can interact with their data.
chrisDeFouRire uses Redis
Session management, Leaderboards, instant messages, and many others use Redis (cluster with Redis Sentinel)
Refractal uses Redis
We use Redis for several different things, but majoritively for server or frontend caching, and session management, both things it excels at.
TribeMedia uses Redis
We use Redis for caching and publish/subscribe coordination for our microservices.
Yaakov-Belch uses Redis
Easy persistence with json semantics that fits my program structure: No searches and no indices where I just have direct references.
Cloudcraft uses Redis
Redis is used for storing all ephemeral (that's data you don't necessarily want to store permanently) user data, such as mapping of session IDs (stored in cookies) to current session variables at Cloudcraft.co. The many datastructures supported by Redis also makes it an excellent caching and realtime statistics layer. It doesn't hurt that the author, Antirez, is the nicest guy ever! These days, I would be really hard pressed to find any situation where I would pick something like Memcached over Redis.
theskyinflames uses Redis
Key/Value store used as NoSQL data source. It also is used as a cache system.
Goyoboard uses Redis
Redis is used for caching and advanced key-value storage to maintain quick access objects and counters. It also used to back resque workers
OnlineCity uses Redis
All data not yet commited to PostgreSQL, lives in multiple redis instances. We are heavy users of lua in redis to enable custom queue behavior.
elo80ka uses Redis
I used Redis to store subscriber preferences (such as language), for which a database would have been overkill.
Banyan uses Redis
Redis is used to cache data which is rarely changed but often requested like huge JSON structures.
GeniusLink uses Redis
Cache for data we need fast. Local regions. We sync some tables with either mysql or mongo.
Giant Swarm uses Redis
Redis is uses in so many places in our stack that we actually can't count it.
jegesh uses Redis
We used Redis to cache server requests, which cut down response times on most requests by at least 1/10.
ReviewTrackers uses Redis
Light weight queueing and smart caching for our data collection processes.
HyperTrack uses Redis
As our in-memory database, to temporarily store individual object properties and query results, which in turn powers our live feed and quick filtering of driver data.
tpp6me uses Redis
Fast cache is used to store short term information from devices and detect change in status of the device.
Divviy uses Redis
Queue to speed up requests of long running operations (e.g. sending email, push notifications)
erayerdin uses Redis
It is used as a caching tool. If a query is made, it is cached in Redis. For 2 minutes, other users see Redis query cache, instead of keeping crawling ESHOT page.
Clarabridge CX Social uses Redis
Used as a caching layer (when we need more functionality than simple key-value storage); keeping lists of online users, used for our smart-assigning feature, keeping track of sliding-window rate limiting information.
AngeloR uses Redis
We use redis as a cache. Nothing too fancy here. At one point we were using it to cache character information, but we've since moved that entirely to DynamoDB and are evaluating the performance before we bring redis back in.
kfancy uses Redis
I use Redis for cacheing, data storage, mining and augmentation, proprietary distributed event system for disparate apps and services to talk to each other, and more. Redis has some very useful native data types for tracking, slicing and dicing information.
emidln uses Redis
Redis makes certain operations very easy. When I need a high-availability store, I typically look elsewhere, but for rapid development with the ability to land on your feet in prod, Redis is great. The available data types make it easy to build non-trivial indexes that would require complex queries in postgres.
Eventvods uses Redis
Provides a super-fast cache layer between our API and database, allowing us to handle surprise bursts of users without overloading database. Response time on a cached request is usually <20ms processing, compared to ~500ms on a heavy database request.
osu! Ripple uses Redis
Redis is probably the single piece of software we love the most. We just love its simplicity, speed and we use it for caching data, storing user sessions, and making leaderboards. It just works perfectly for us.
jflynn33 uses Redis
Simple caching, tightly tied into Rails. Optimized caching without any work to implement. Done.
Scrayos UG (haftungsbeschränkt) uses Redis
We make extensive use of Redis for our caches and use it as a way to save "semi-permanent" stuff like user-submit settings (that get refreshed on each login) or cooldowns that expire very fast.
rahulsmehta uses Redis
We used Redis to implement a locking mechanism for ensuring consistency while multiple users were editing the same file.
Stream uses Redis
Redis makes it easy to synchronize state over multiple nodes in the realtime cluster.
andrewgatenby uses Redis
We use Redis for a fast and scalable solution to caching data within our API.
