Redis, a fast, reliable and well supported data storage system

Eric Mason
Score 9 out of 10
Vetted Review

Pros and Cons

  • 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

Vetted Review

Pros and Cons

  • 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.

Best DB for a gaming company willing to scale overnight

Vetted Review

Pros and Cons

  • 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).

Pros and Cons

  • 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.

Pros and Cons

  • 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

Leonel Quinteros
Score 9 out of 10
Vetted Review
Verified User
Review Source

Pros and Cons

  • 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.

Pros and Cons

  • 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.

Pros and Cons

  • 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.

Pros and Cons

  • 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.

Pros and Cons

  • 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.

  • 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.

  • 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

About 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.
