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.

  • Reductions in latency allow operations that would be longer running (multiple seconds) to be performed nearly instantaneously providing for high performance.
  • Redis allows for easier application scaling and support for a higher volume of transactions without typical performance curve limitations.
  • Savings related to not having to pre-process unstructured data are hard to quantify but very appreciated in the sense of savings on code complexity.

  • 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.

  • With a sub-millisecond latency, we were able to serve more than 500K HTTP requests per minute, with Redis serving more than 10 million ops/sec.
  • When we migrated to Redis on Flash (Redis labs enterprise solution), our infrastructure costs were reduced by 50% (AWS ec2 instances & EBS resources).
  • Our main game stores its data in Redis, with more than 300 million users and a total data of more than 6TB of information.

  • Redis is very easy to set up, not only as a stand-alone service but also in a local Docker container. This makes local development and testing extremely easy.
  • Redis is considerably cheaper than a fully managed key-value store such as DynamoDB.
  • Redis can provide the cache layer a lot of services need, which improves the performance of those services.

  • Performance has increased
  • Reliability has improved greatly compared to when we ran everything on SQL

  • Existing tools like Redisson that were built over Redis reduced dev time in solving challenging problems, which had a positive impact on ROI.
  • We initially misused Redis for persistent storage which had a negative impact on ROI because we were paying a lot for inactive users.
  • The increased performance we achieved using Redis in areas like locking helped us improve the performance of our system reducing the likelihood of system timeouts.

  • Reduced load to the primary transactional database.
  • Ability to launch open source-based solutions backed by Redis quickly to reduce "not invented here" within engineering.
  • Reduced infrastructure gave Redis' small footprint and flexibility for temporary caching as well as permanent storage.

  • Implementing Redis for the first time in a project was super easy and it didn't add any noticeable cost to development or release processes.
  • Replacing Memcached use cases with Redis was also almost entirely transparent during implementation.
  • Having a high-performance/high-availability software solution for free and open source is a great option in this market.
