Feed: Redis. Author: John Noonan. What is high availability architecture? A high available architecture is when there are a number of different components, modules, or services that work together to maintain optimal performance, irrespective of peak-time loads. In its purest sense, this system allows businesses to work continuously without failure over a given period of time. Many businesses can’t afford even a minute of downtime. Considering that data is the lifeblood of many businesses, even just a short period of downtime can be incredibly costly.  In certain real-life scenarios, lives may depend on a database built for high availability. When ... Read More

Feed: Redis. Author: Steve Naventi. Launching an airplane from an aircraft carrier is a systematic and well coordinated process that involves reliable systems, high-performance catapults, precise navigation systems, and above all, a specialized crew having different roles and responsibilities for managing air operations. This crew, also known as the flight deck crew, are known for their colored jerseys to visually distinguish their functions. Everyone associated with the flight deck has a specific job. As a corollary to this example, launching machine learning (ML) models into production are not entirely different, except instead of launching a 45,000-pound plane into air, ML ... Read More

Feed: Redis. Author: Yiftach Shoolman. When interesting ideas and discussions about whether Redis’ architecture is still valid for today and future needs we think it is worth examining. A few years ago it was brought up around KeyDB, and recently a new project, Dragonfly, claimed to be the fastest Redis-compatible in-memory datastore. We believe these projects bring many interesting technologies and ideas worth discussing and debating. Here at Redis, we like this kind of challenge, as it requires us to reaffirm the architectural principles that Redis was initially designed with (hat tip to Salvatore Sanfilippo aka antirez). While we are ... Read More

Feed: Redis. Author: Paula Dallabetta. What is a schemaless database? A schemaless database manages information without the need for a blueprint. The onset of building a schemaless database doesn’t rely on conforming to certain fields, tables, or data model structures. There is no Relational Database Management System (RDBMS) to enforce any specific kind of structure. In other words, it’s a non-relational database that can handle any database type, whether that be a key-value store, document store, in-memory, column-oriented, or graph data model. NoSQL databases’ flexibility is responsible for the rising popularity of a schemaless approach and is often considered more ... Read More

Feed: Redis. Author: Filipe Oliveira. Redis is developed with a great emphasis on performance. We do our best with every release to ensure you’ll experience a very stable and fast product. Nevertheless, if you’re finding room to improve the efficiency of Redis or are pursuing a performance regression investigation, you will need a concise methodical way of monitoring and analyzing Redis’ performance. This is the story of one of those optimizations. In the end, we’ve improved stream’s ingest performance by around 20%, an improvement you can already take advantage of on the Redis v7.0. A standard SPEC Before jumping into ... Read More

Feed: Redis. Author: John Noonan. What is database consistency? Database consistency is defined by a set of values that all data points within the database system must align to in order to be properly read and accepted. Should any data that does not meet the preconditioned values enter the database, it will result in consistency errors for the dataset. Database consistency is achieved by establishing rules. Any transaction of data written to the database must only change affected data as defined by the specific constraints, triggers, variables, cascades, etc., established by the rules set by the database’s developer. For example, ... Read More

The simple answer is speed.  Business leaders are challenging their IT and technology teams to release mission-critical applications and data service MVPs faster than ever before. And the pace and expectations are only going to accelerate.  Shawn Bice, President of Products and Technology at Splunk, believes this accelerated ... Read More

Feed: Redis. Author: Brandon Felker. Redis Enterprise 6.2.4 introduced internode encryption. The scope of internode encryption in Redis Enterprise is to achieve TLS encryption for all internal Redis cluster connections between nodes, including: Enhancing control plane connections to encrypt CCS (Cluster Configuration Store) replication.All connections to primary node CCS from replica nodes.Data plane connections to encrypt shard replication between nodes. All proxy to shard connections between nodes. Redis Enterprise: Design Considerations Redis Enterprise uses several techniques to optimize performance and availability. The Redis cluster uses a shared-nothing architecture, which increases reliability and availability and makes it easy to add and remove ... Read More
