Redis Labs Extends Reach of In-Memory Database

At its online RedisConf 2021 event, Redis Labs today detailed how the company’s in-memory database will be employed to drive real-time applications that are at the core of most digital business transformation initiatives.

Yiftach Shoolman, Redis Labs CTO and co-founder, said there are four initiatives at the core of the Redis Labs effort to replace legacy databases that organizations have historically employed to drive batch-oriented application processes.

RedisRaft, which will become available with release 7.0 of the Redis database in the third quarter, provides a module based on the Raft consensus algorithm that enable multiple Redis servers to be consumed by an application as if they were one single, fault-tolerant, logical cluster. That capability will provide IT teams with the ability to distribute Redis servers closer to the point where data is being consumed by a distributed application without incurring any conflicts between databases, said Shoolman.

At the same time, Redis is extending its Active-Active technology to enable integrated data models to be deployed in a way that allows distributed applications to run as close as possible to the point where data is being created and consumed.

Finally, RediSearch is being updated to include support for indexing capabilities in JSON applications using a nested document model, while a RedisAI capability will add an inference engine for artificial intelligence (AI) applications that can be employed as a feature store through which the deployment of AI models within applications can be managed. That approach also promises to significantly increase the overall performance of AI applications, noted Shoolman.

Historically, the Redis in-memory database has been best known for the caching capabilities it provides developers. However, Shoolman noted 66% of organizations that employ the Redis database are using it for additional use cases. As microservices that are often configured with their own database become more prevalent, the adoption of an in-memory database platform should only increase, added Shoolman.

Many of those microservices are being employed within the context of a digital business transformation project. The issue that organizations are coming to terms with is most of those processes need to run in near real-time. That requirement will eventually push more organizations toward deploying a database based on a distributed database running in-memory that appears as one logical entity to an application, said Shoolman.

At its core, Redis a data store that supports structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams. Among other capabilities, it includes support for built-in replication, Lua scripting, transactions and varying levels of persistence. The company claims the core Redis data store has been downloaded 1.5 million times in the last nine years.

On top of that installed base, Redis Labs then makes available tools for deploying and managing Redis within large-scale application environments. Most recently, Redis Labs raised an additional $100 million round of financing to bring its valuation to above $2 billion. The company now claims to have more than 8,000 paying customers, with a 54% compound annual growth rate in sales for the past three years.

It’s hard to say to what degree Redis data stores might supplant legacy database platforms. However, the one thing that is certain is there are lot more databases running in memory that, in many cases, obviate the need for a traditional relational database.
