Cached lookup

If you're using multiple databases, you may want to avoid making a query to the central database on each tenant request — for tenant identification. Even though the queries are very simple, the app has to establish a connection with the central database which is expensive.

To avoid this, you may enable caching on the tenant resolvers (all in the Stancl\Tenancy\Resolvers namespace):

• DomainTenantResolver (also used for subdomain identification)
• PathTenantResolver
• RequestDataTenantResolver

On each of these classes, you may set the following static properties:

// TenancyServiceProvider::boot()

use Stancl\Tenancy\Resolvers;

 // enable cache
DomainTenantResolver::$shouldCache = true;

// seconds, 3600 is the default value
DomainTenantResolver::$cacheTTL = 3600;

// specify some cache store
// null resolves to the default cache store
DomainTenantResolver::$cacheStore = 'redis';
