描述

Problem

Sometimes users can run smth like 'Select many dimensions and metrics for long period ". When it happens, huge portion of data is added to memory cache (we are still using redis, but I think problem will remain after adding cube store).

How can we disable adding result of query to cache by its size (e.g. limit 30 mb)? For us it's cheaper to make roundrip to db)

研究方向
Review Cube.js caching implementation, likely in `packages/cubejs server` or `src/cache`. The user requests a per query cache size limit. Investigate configuration options and propose adding a new setting like `maxCacheSize` to skip caching for queries exceeding a threshold. Check if there are any open PRs or comments discussing similar approaches.
