ClickHouse is an open-source columnar database management system designed for real-time analytical queries over large datasets. Unlike row-oriented databases such as MySQL or PostgreSQL, ClickHouse stores data by column, allowing it to scan only the columns needed for a query and apply aggressive compression, resulting in query performance orders of magnitude faster for analytical workloads.

Introduction Deploying configure database backups with automysqlbackup on debian 12 on a Debian 12 Bookworm machine is straightforward thanks to Debian’s policy-compliant packaging. Unlike rpm-based distributions, Debian stores configuration helpers in /etc/default/, uses update-rc.d for older init scripts, and provides dpkg-reconfigure for interactive package configuration. This tutorial stays on the systemd path throughout. Prerequisites Before […]
Introduction How to Install SQLite3 on Debian 12 is a fundamental operation for any administrator maintaining a Debian 12 Bookworm server.

PostgreSQL provides two complementary tools for database backups: pg_dump and pg_basebackup. pg_dump takes logical backups of individual databases or selected objects and can restore to a different PostgreSQL version or host. pg_basebackup takes a physical, byte-for-byte copy of the entire data directory, which is the foundation of streaming replication and point-in-time recovery. This tutorial covers […]
Introduction Debian 12 Bookworm is built around the ethos of stability and free software. Setting up set up couchdb on debian 12 on Bookworm leverages the same proven Debian packaging system that powers millions of servers worldwide, while benefiting from the latest upstream releases included in the Bookworm freeze.

PostgreSQL streaming replication continuously ships Write-Ahead Log (WAL) records from a primary server to one or more standby replicas in near real time. The standby can serve as a warm failover target or, in hot-standby mode, accept read-only queries to offload reporting traffic from the primary. This tutorial configures a two-node streaming replication setup on […]
Introduction This guide explains how to Install and Configure InfluxDB 2 on Debian 12 on Debian 12 Bookworm. Debian Bookworm uses systemd for service management, nftables as the underlying packet filter (with ufw or iptables front-ends still available), and AppArmor for mandatory access control. Every command is designed for a minimal Debian 12 install with […]
