A concise architecture note on the minimal viable Confluence Data Center cluster: two nodes, shared database, POSIX shared home, Hazelcast TCP‑IP cache, and the operational checks that prevent split‑brain and index corruption.
Decide when to enable native GeoJSON clustering in Mapbox GL JS, how to style clusters, and how to validate click and performance behavior.
Optimize Vert.x service-to-service communication using custom MessageCodecs and the request-reply pattern to send domain objects across a clustered event bus without blocking.
Proxmox VE HA uses Pacemaker to move VMs automatically when a node fails. This guide walks through cluster prerequisites, fencing, a live failover test, and the trade‑offs you need to consider before enabling HA.
Learn how to scale Node.js applications across all CPU cores using PM2 Cluster Mode to eliminate single-threaded bottlenecks and achieve zero-downtime reloads.
Learn how to combine BigQuery partitioning and clustering to cut query costs and improve performance, with a concrete web‑events example and verification steps.
Partition BigQuery tables by a DATE or TIMESTAMP column and cluster by filter columns so on-demand queries scan fewer bytes. Verify savings with free dry runs.
PM2 cluster mode can keep your Node.js API online while you reload workers one at a time. Learn how to enable it, test zero‑downtime reloads, and understand the trade‑offs for long‑lived connections.
