This guide explains how to establish a connection between a Java application and a Redis database using the Jedis library. It walks through the necessary setup, configuration, and execution of a simple Redis command. Variables Certain parameters must be prov...

This guide explains how to establish a connection between RedisInsight and a Redis database instance. It walks through the necessary setup, configuration, and connection steps using the official Redis GUI. Variables Certain parameters must be provided to est...

This guide explains how to establish a connection between redis-cli and a Redis database instance. It walks through the necessary setup, configuration, and execution of a simple Redis command from the terminal. Variables Certain parameters must be provided t...

Redis is a popular in-memory key-value data store known for its speed, flexibility, and support for a wide range of data structures. Setting up Redis properly is essential to ensure high availability, data persistence, and performance in modern applications. T...

Upgrading a database service on Elestio can be done without creating a new instance or performing a full manual migration. Elestio provides a built-in option to change the database version directly from the dashboard. This is useful for cases where the upgrade...

Redis supports modules to extend core functionality with new data types, commands, or algorithms. These modules behave like plugins in other systems and are loaded at server startup. Examples include RedisBloom, RedisTimeSeries, RedisJSON, and RedisSearch. In...

Regular backups are essential when running a Redis deployment especially if you’re using it for persistent data. While Elestio handles automated backups by default, you may want to create manual backups before configuration changes, retain a local archive, or ...

Restoring Redis backups is essential for disaster recovery, staging environment duplication, or rolling back to a known state. Elestio supports backup restoration both through its web dashboard and manually through Docker Compose and command-line methods. This...

Slow commands can impact Redis performance, especially under high load or when poorly optimized operations are used. Whether you’re using Redis on Elestio through the dashboard, accessing it inside a Docker Compose container, or connecting via CLI tools, Redis...

Long-running commands in Redis can block the single-threaded event loop, causing delayed responses or complete unresponsiveness in production environments like Elestio. Monitoring and handling these commands is critical for maintaining performance and reliabil...

Running out of disk space in a Redis environment can lead to failed writes, snapshot errors, and service unavailability. Redis relies on disk storage for persistence (RDB and AOF files), temporary dumps, and logs especially when persistence is enabled. On plat...

As your Redis data grows especially when using persistence modes like RDB or AOF it’s important to track how storage is being used. Unchecked growth can lead to full disks, failed writes, longer startup times, and backup complications. While Elestio handles th...

At Elestio, we're committed to transparency and simplicity when it comes to billing. One area where we often receive questions is bandwidth usage, especially what happens after your allocated free bandwidth is exceeded. This post will walk you through how band...

ClickHouse is an open-source columnar database management system designed for online analytical processing (OLAP). It enables fast processing of large volumes of data by storing data by columns instead of rows, making it highly efficient for analytical queries...

Elestio provides a complete solution for setting up and managing software clusters. This helps users deploy, scale, and maintain applications more reliably. Clustering improves performance and ensures that services remain available, even if one part of the sys...

Creating a cluster is a foundational step when deploying services in Elestio. Clusters provide isolated environments where you can run containerized workloads, databases, and applications. Elestio’s web dashboard helps the process, allowing you to configure ...

Node management plays a critical role in operating reliable and scalable infrastructure on Elestio. Whether you’re deploying stateless applications or stateful services like databases, managing the underlying compute units nodes is essential for maintaining st...

As your application usage grows or your infrastructure requirements change, scaling your cluster becomes essential. In Elestio, you can scale horizontally by adding new nodes to an existing cluster. This operation allows you to expand your compute capacity, im...

Clusters can be designed for high availability or role-based workloads, where certain nodes may take on leadership or coordination responsibilities. In these scenarios, promoting a node is a key administrative task. It allows you to change the role of a node. ...

Over time, infrastructure needs change. You may scale down a cluster after peak load, decommission outdated resources, or remove a node that is no longer needed for cost, isolation, or maintenance reasons. Removing a node from a cluster is a safe and structure...
