Removing queries from cache

You can manually remove a cached query from cache before its natural TTL-driven expiration time by using the DatabaseProvider::clearCacheQuery method, here's an example:

    "uniqueId" => "usersSignedUpLast24Hours"

Because query cache keys are automatically generated if you don't specify any Cache key naming when calling methods like DatabaseProvider::queryCache and DatabaseProvider::prepareAndExecuteCache, you can only remove queries from cache that have been originally performed with a specific Cache key naming.

The most usual way to cache queries and then be able to remove them whenever we need is to use a known uniqueId for each query, like in the example above.
