Why it matters
This feature addresses the need for more flexible and fair IO resource allocation in ClickHouse. It allows better control over IO bandwidth distribution among queries or users by applying weight-based scheduling. The dynamic resource manager enhances operational efficiency by enabling real-time updates to IO scheduling policies without downtime.How to use it
To use this feature, configure the weighted fair IO scheduling policy in the resource manager settings. You can dynamically update the IO scheduling hierarchy during runtime via the ClickHouse configuration or resource manager interfaces without restarting the server.
