v.24.4Experimental Feature

Userspace Page Cache Supports Static Web Storage

Official CH changelog text
Userspace page cache works with static web storage (disk(type = web)) now. Use client setting use_page_cache_for_disks_without_file_cache=1 to enable. #61911 (Michael Kolupaev).
Userspace page cache support for static web storage has been added, allowing improved caching for disks configured with disk(type = web).

Why it matters

This feature enables caching of data accessed from static web storage disks, which previously did not benefit from the userspace page cache. It improves read performance and reduces latency for data stored on web-based storage by utilizing the page cache mechanism.

How to use it

To enable this feature, set the client setting use_page_cache_for_disks_without_file_cache=1. This will activate userspace page cache for disks defined as disk(type = web).
