ClickHouse supports custom extensions via [User Defined Functions (UDFs)], external dictionaries, and shared libraries that extend its core capabilities with custom logic, formats, or integrations. These behave similarly to modules or plugins in other systems ...

Regular backups are essential when running a ClickHouse deployment, especially if you’re using it for persistent analytics or time-series data. While Elestio handles automated backups by default, you may want to create manual backups before configuration chang...

Restoring ClickHouse 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....

Slow queries can impact ClickHouse performance, especially under high load or with inefficient queries or schema design. Whether you’re using ClickHouse on Elestio via the dashboard, accessing it inside a Docker Compose container, or running CLI queries, Click...

ClickHouse is a high-performance, column-oriented OLAP database, but poorly optimized or long-running queries can still impact performance especially in resource-constrained environments like Elestio. Because ClickHouse executes large queries across multiple t...

Running out of disk space in a ClickHouse environment can cause query failures, part merge errors, and even full service downtime. ClickHouse is highly dependent on disk for storing columnar data, part files, metadata, temporary sort buffers, and backups. On p...

As your ClickHouse data grows especially with large analytical workloads or high-ingestion pipelines it’s important to track how storage is being used. Unchecked growth can lead to full disks, failed inserts, increased merge times, and slower queries. While El...

Tabix is a lightweight browser-based GUI for ClickHouse that lets you browse tables, write queries, and manage your ClickHouse instance using a preconfigured admin dashboard provided by Elestio. Variables To connect using Tabix, you’ll need the following log...

Keycloak is an open-source identity and access management (IAM) solution aimed at modern applications and services. It provides features such as single sign-on (SSO), user federation, identity brokering, and social login. Designed for flexibility and scalabili...

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 co...

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...

Reliable backups are essential for data resilience, recovery, and business continuity. Elestio provides built-in support for managing backups across all supported services, ensuring that your data is protected against accidental loss, corruption, or infrastruc...

Securing access to services is a fundamental part of managing cloud infrastructure. One of the most effective ways to reduce unauthorized access is by restricting connectivity to a defined set of IP addresses. Elestio supports IP-based access control through i...

In distributed systems, consistency and synchronization between nodes are critical to ensure that services behave reliably and that data remains accurate across the cluster. Elestio provides built-in mechanisms to detect and resolve inconsistencies across node...

When a cluster is no longer needed—whether it was created for testing, staging, or an obsolete workload—deleting it helps free up resources and maintain a clean infrastructure footprint. Elestio provides a straightforward and secure way to delete entire cluste...

Elestio enables seamless migration of Keycloak realms by supporting realm exports and imports. This capability is vital for backing up configurations, replicating environments, or transitioning between staging and production systems. The process ensures consis...
