Don't miss the #PostgreSQL #Backups & #Replication course by @dataegret :postgresql:

Five live online sessions designed to take your PostgreSQL backup and replication knowledge to the next level.

You will spend some quality time with me. Do not worry, I am friendly and only slightly emotional about backups 🔥🧯🤣

Big secret (#sarcasm): the first part of the training will, of course, focus on #pgBackRest 🫢

Weekend well spent on #homelab upgrades:

📈 3 -> 5 node #K3s cluster,
💪 single-node etcd -> 3 node etcd for #HighAvailability,
💿 updated k3s version,
🧹 tidied up some cabling on home rack.

All set for a #medialab installation !

Next up:
- find some time for that ... 😅

Giới thiệu pg-status — microservice nhẹ giúp kiểm tra trạng thái PostgreSQL host, xác định master và replica đồng bộ, hỗ trợ failover và cân bằng tải. Dễ triển khai dạng sidecar, viết bằng C, hiệu năng cao (1500 RPS), API đơn giản qua HTTP. Hỗ trợ đo độ trễ theo thời gian/bytes, tích hợp với libpq hoặc proxy. Phù hợp cho hệ thống cần độ tin cậy cao và phản ứng nhanh với sự cố. #PostgreSQL #Database #DevOps #Microservice #C #HighAvailability #pgstatus #sidecar #replication #failover #trạng_thái_C

Image composition of the HArmadillium mascot, named Bitto: a friendly brown armadillo with a textured shell. The main, larger figure is wearing a blue jacket with visible circuit board patterns, is waving, and holds a glowing blue energy sphere in the other hand. The logo and the writing "HArmadillium" are displayed on the jacket. Surrounding the main mascot are several smaller versions of Bitto in various poses, some with and some without the blue tech jacket. The mascot symbolizes High Availability clusters.Image composition of the HArmadillium mascot, named Bitto: a friendly brown armadillo with a textured shell.

Confluent Stretched Cluster 2.5 introduces powerful mechanisms — such as observers and Automatic Observer Promotion (AOP) — to enhance cross-datacenter resilience while reducing operational complexity. See how replication factor and min.insync.replicas impact the availability and fault tolerance of such an architecture.

Do we need to mention that Coocook.org was NOT affected by the #AWSdown #USEast1 disaster? 😜

Instead, to be honest, it’s running on a 10+ year old 1U server at a community-organized ISP in my hometown #Leipzig without any complex #HighAvailability setup. The machine has been running like this surprisingly steady all those years 🙈
