I spent an afternoon this week setting up my first MySQL master-slave replication, and a simple firewall rule cost me two hours of debugging. As part of my DevOps learning journey, I was provisioning two Ubuntu 22.04 servers to create a basic primary-replica database architecture with MySQL 8.0. I followed the guide carefully: configured the master's `my.cnf` with `log_bin` and a unique `server-id`, created a dedicated 'replicator' user with the right grants, and noted the master's binary log file and position. Everything looked perfect on paper. But the slave steadfastly refused to connect. The `SHOW SLAVE STATUS` command was stuck on 'Connecting to master', but `Last_IO_Error` was frustratingly empty. I triple-checked the user grants, passwords, and log positions. The real issue was completely outside MySQL: a default cloud firewall rule was blocking ingress traffic on port 3306 to the master server. 💡 The lesson was to always validate the network path before debugging the application layer. My new checklist is simple: 1. `ping <master_ip>` to check basic ICMP connectivity. 2. `nc -zv <master_ip> 3306` or `telnet <master_ip> 3306` from the slave to confirm the specific application port is open and listening. This two-step check would have revealed the problem in seconds. How do you automate pre-flight checks for infrastructure dependencies like network paths when deploying stateful services? #DevOpsJourney #MySQL #Database #Linux #SysAdmin #LearningInPublic 💡

PostgreSQL ==> Citus (or reverse) using FastTransfer parallel copy. We compare parallel copy method available in FastTransfer. Citus is a postgresql extension (linux only) that allow you to store data in a columnar format into a postgresql database. Columnar format is a good choice for analytics workloads. https://lnkd.in/dK4k7KaB #FastTransfer #PostgreSQL #Citus

📰 My latest article “PostgreSQL and Huge Pages: Boosting Database Performance the Right Way.” 📰 I explore how enabling Huge Pages on Linux can significantly improve PostgreSQL performance, especially on bare metal servers with large amounts of RAM. Managing memory through small 4 KB pages can create unnecessary overhead — something Huge Pages help eliminate by reducing CPU usage and improving stability. 📰 The article walks through how to check if Huge Pages are in use, how to configure them properly, and what pitfalls to avoid. 📰 It’s a practical guide for anyone running PostgreSQL on high-performance or production systems. If you’re working with database optimization, system tuning, or managing bare metal infrastructure, I hope you find it useful. #postgresqsl #postgres #databases #sql #dataops

🚀 Performance Boost in PostgreSQL 18 with I/O Method Enhancements! In my recent benchmarking tests using pgbench, I compared the performance of PostgreSQL 17.6, PostgreSQL 18 without I/O method, and PostgreSQL 18 with I/O method (io_uring) enabled. Here’s what I found: PostgreSQL Version I/O Method TPS (Transactions/sec) Avg. Latency (ms) 🔹️17.6 default 2,708.9 Avg. Latency 3.692 ms 🔹️18 (without I/O method) worker 6,584.8 Avg. Latency 1.519 ms 🔹️18 (with I/O method) io_uring 6,821.5 Avg. Latency 1.466 ms That’s an impressive 2.5x performance improvement from version 17.6 to 18, and an additional gain with the new io_uring I/O method! This new parameter unlocks more efficient I/O handling, reducing latency and improving transaction throughput — a big step forward for database performance on Linux systems. #PostgreSQL #DatabasePerformance #OpenSource #Benchmarking #Tech #Innovation
