ClearKey: A Silverstripe module to manage partial-cache invalidation
====================================================================

[](#clearkey-a-silverstripe-module-to-manage-partial-cache-invalidation)

When using Silverstripe’s partial caching, the keys you use can usually be grouped into two types.

1. Cache *identifier* keys, which help tell one cache block from another
2. Cache *clearing* keys, which tell us when a block is stale

Take this partial-cache block as an example:

```

...

```

These *identifier* keys help tell one promo from another:

- `'Promo'`
- `$ID`
- `$Link`

These *clearing* keys help tell us when the content is stale:

- `Promo.LastEdited`
- `$List('SiteTree').max('LastEdited')`
- `$List('SiteTree').count()`

Partial caches do a great job with *identifier* keys, but have to hit the database at every page load to calculate some of the *clearing* keys, especially the aggregation ones.

ClearKey solves this by letting you manage the calculating of clearing of stale data whenever a relevant data object is saved, instead of on every page load. With ClearKey, the example cache block might look like this:

```

...

```

You define the clear keys with a corresponding config to describe which classes being updated should invalidate each key. In the example below, the `Promo` key is invaldated whenever a `Promo` or `SiteTree` is saved.

```

Name: clearkey-config

      - SilverStripe\CMS\Model\SiteTree
    AnotherKey:
      - SilverStripe\App\Model\Something
      - SilverStripe\CMS\Model\Etc

```
