SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Primary Day-2 vertical scale entry to adjust CPU and memory on existing KubeBlocks-managed database clusters, enabling predictable performance and safe capacity management.

Core Features & Use Cases

  • Day-2 vertical scaling for existing clusters to match workload demands.
  • Confirm support in the ops capability matrix before acting.
  • Route monitoring to kubeblocks-observability-router and trigger broken-state diagnosis via kubeblocks-troubleshoot.
  • Maintains compatibility shim with legacy kubeblocks-vertical-scaling when needed.

Quick Start

Identify the target cluster and engine, verify support in the ops capability matrix, and perform the CPU or memory adjustment following the workflow.

FAQPage Schema
How do I vertically scale CPU and memory for an existing KubeBlocks database cluster?▼

Vertical scaling in KubeBlocks adjusts CPU and memory on existing database clusters. You must verify engine support in the ops capability matrix before applying resource adjustments to match workload demands.

How does KubeBlocks verify support before a Day-2 vertical scaling operation?▼

KubeBlocks checks vertical scaling support by validating the target database engine against the ops capability matrix. This ensures the cluster permits CPU and memory adjustments before action.

What happens if vertical scaling causes a database cluster to enter a broken state?▼

If vertical scaling causes a broken state, KubeBlocks routes monitoring data to the observability-router and triggers diagnosis via the kubeblocks-troubleshoot tool to identify the failure.

Does KubeBlocks vertical scaling provide a rollback plan for database capacity adjustments?▼

Yes, KubeBlocks Day-2 vertical scaling includes rollback planning for CPU and memory adjustments. This ensures safe capacity management when modifying existing database clusters.
