How GaussDB’s Fine‑Grained Resource Control Optimizes Multi‑Tenant Performance

GaussDB provides a fine‑grained resource control solution that lets administrators define CPU, memory, I/O, connection, concurrency, and storage limits at user, session, and statement levels, using resource pools, control groups, and GUC parameters to ensure multi‑tenant isolation, SLA compliance, and optimal cluster utilization.

Understanding Linux cgroups and Controlling Process CPU Usage

The article introduces Linux cgroups as a kernel feature for limiting resources, explains their terminology and functions, and demonstrates a hands‑on experiment that creates a CPU cgroup, sets cpu.cfs_quota_us to restrict a process to roughly 25 % CPU usage, confirming effective resource control.

Understanding Linux cgroups: Concepts, Hierarchy, and Usage

Linux cgroups are a kernel feature that organizes processes into hierarchical control groups, allowing fine‑grained limits, accounting, and isolation of CPU, memory, I/O, network and devices via subsystems such as cpu, memory, cpuset, blkio, and others, and are accessed through a virtual filesystem for configuring and managing resource constraints, underpinning containers and cloud platforms.
