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
DomainTenantResolver(also used for subdomain identification)
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::$cacheStore = 'redis';
Updating and saving a Tenant model's attributes will cause the cached entry for this model to be invalidated when
DomainTenantResolver::$shouldCache is set to
You may invalidate the cache by calling :
Note: When using the domain identification, the key of the cache contains the name of the domain. Make sure to invalidate the cache before making any changes if you intend to update the domain name.
