Cache Inspector

The Cache Inspector shows cache statistics when a CacheBridge is attached to the Studio context. If caching is off, it reports enabled: false.

Open it

Section titled “Open it”
  1. Open Studio (mountsqli dev) with caching configured.
  2. Go to the Cache view.

What it shows

Section titled “What it shows”
Metric Meaning
Hits / Misses how often cached results were reused
Evictions entries removed by the eviction policy
Size current entry count
Tags which tags are present

Prerequisites

Section titled “Prerequisites”

The inspector reads from a CacheBridge passed to makeStudioContext. In the CLI dev server, this is wired when your config includes a cache section.

import { makeStudioContext } from "@mountsqli/studio";
const ctx = makeStudioContext(db, cacheBridge);

Best practices

Section titled “Best practices”
  • Watch hit rate to confirm your cache keys are stable.
  • Use tags to verify invalidation fires on writes.

Common mistakes

Section titled “Common mistakes”
  • Opening the view without a cache configured — it shows enabled: false.
  • Reading size as a health signal without hit rate context.
