Dynamic loaders - Githubissues

Hey @romm, after a while i came back to the same performance issue. My app works in microservice enviroment and simplified workflow is:

start thread
preload services (including valinor)
connect network services
get preloaded modules
inject modules autolaoders and run bootstrap
process requests (some requests can load additional modules)
after 500 requests or 100 preloaded modules thread restarts

Atm i recreate mapper and normalizer after every module loaded. Example intrface:

#[TypedInterface([
    'column.add' => AddColumnDto::class,
    'column.drop' => DropColumnDto::class,
    'column.rename' => RenameColumnDto::class,
    'relation.add' => AddRelationDTO::class,
    'relation.drop' => DropRelationDto::class,
])]
interface AlterOperation {}

and methods to add interfaces like this in MapperBuilder:

    public function onModuleLoaded(string $namespace){
        $updated = false;
        foreach($this->findInterafaces($namespace) as $interfaceName){
            $attr = $this->readAttributes($interfaceName);
            if (!$attr) continue;
            $this->mapperBuilder = $this->mapperBuilder->infer($this->generateInfer($attr->param, $attr->map));
            $updated = true;
        }
        if ($updated){
            $this->mapper = $this->mapperBuilder->mapper();
            $this->normalizer = $this->mapperBuilder->normalizer(Format::array());
        }
    }

    public function generateInfer(string $param_name, array $classmap){
        $tmpfile = tempnam(sys_get_temp_dir(), 'valinor');
        $variants = implode(' | ', $classmap);
        $mapdump = var_export($classmap, true);
        $content = <<<EOT
\$classmap = $mapdump;
/**
 * @return class-string<$variants>
 */
return fn (string \$$param_name) use (\$classmap) => \$classmap[\$$param_name] ?? 'Unknown'.\$$param_name;
EOT;
        file_put_contents($tmpfile, $content);
        $method = include $tmpfile;
        unlink($tmpfile);
        return $method;
    }

I tried to implement some more generic solution in #560 with no success. is there a better way to implement it?
