Hydra allows you to create databases using different methods, including the PostgreSQL interactive shell (psql), Docker (assuming Hydra is running inside a container), and the command-line interface (createdb). This guide explains each method step-by-step, cov...

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...

Hydra supports a growing range of PostgreSQL-compatible extensions that add extra functionality to the core database system. Extensions like pg_trgm (for text search) and some UUID utilities are used to extend native capabilities. However, not all PostgreSQL e...

Regular backups are a key part of managing a Hydra deployment. While Elestio provides automated backups by default, you may want to perform manual backups for specific reasons, such as preparing for a major change, keeping a local copy, or testing backup autom...

Restoring backups is essential for recovery, environment duplication, or rollback scenarios. Elestio supports restoring backups both through its built-in dashboard and via command-line tools like pg_restore psql. You can also restore from inside Docker Compose...

Long-running queries can significantly impact database performance by consuming CPU, memory, and I/O resources over extended periods. In production environments like Elestio, it’s important to monitor for these queries and take timely action to terminate them ...

Running out of disk space in a database environment can lead to failed writes, service downtime, and even data corruption. Hydra systems require available space not only for storing data but also for managing temporary files, WAL logs, indexes, and routine bac...

As your Hydra database grows over time, it’s important to monitor its size and identify what parts of the database consume the most space. Unmanaged growth can lead to performance issues, disk exhaustion, and backup delays. On Elestio, where Hydra is hosted in...

Slow queries can significantly affect application performance and user experience. Hydra offers built-in tools to analyze and identify these slow operations. On Elestio, whether you’re connected via terminal, inside a Docker Compose container, or using Hydra C...

TimescaleDB is an open-source time-series database engineered for fast, scalable ingestion and complex analytics on time-series data. Built as a PostgreSQL extension, TimescaleDB combines the reliability, flexibility, and SQL support of PostgreSQL with powerfu...

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 managing production-grade services, the ability to perform reliable and repeatable database migrations is critical. Whether you’re applying schema changes, updating seed data, or managing version-controlled transitions, Elestio provides a built-in mechani...
