Performance & caching¶
This library needs to parse a lot of information in order to handle all provided features. Therefore, it is strongly advised to activate the cache to reduce heavy workload between runtimes, especially when the application runs in a production environment.
The library provides a cache implementation out of the box, which saves cache entries into the file system.
It is also possible to use any PSR-16 compliant implementation, as long as it is capable of caching the entries handled by the library.
When the application runs in a development environment, the cache implementation
should be decorated with
FileWatchingCache, which will watch the files of the
application and invalidate cache entries when a PHP file is modified by a
developer — preventing the library not behaving as expected when the signature
of a property or a method changes.
Warming up cache¶
The cache can be warmed up, for instance in a pipeline during the build and deployment of the application.
The cache has to be registered first, otherwise the warmup will end up being useless.
$cache = new \CuyZ\Valinor\Cache\FileSystemCache('path/to/cache-dir'); $mapperBuilder = (new \CuyZ\Valinor\MapperBuilder())->withCache($cache); // During the build: $mapperBuilder->warmup(SomeClass::class, SomeOtherClass::class); // In the application: $mapper->mapper()->map(SomeClass::class, [/* … */]);
