I have to perform a query that can generates a very big string in response (up to 1Gb), which is basically a big, big JSON array. Yes, pagination is in order but I'm stressing the concept in order to get you the idea. Symfony simply uses doctrine to get the response:
$stmt = $this->getEntityManager()->getConnection()->prepare(self::Q_GET_NUM_TIMEBOX);
$stmt->bindValue('t_end', $tEnd);
$stmt->bindValue('t_granularity', $tGranularity);
$stmt->bindValue('t_span', $varSelection->getStart());
$stmt->execute();
$resData = $stmt->fetchColumn(0);
and then I create a Response
by setting the content I had in return from the execute.
$res = new Response();
$res->setStatusCode(200);
$res->headers->set('Content-Type', 'application/json');
$res->setContent($resData);
Keep in mind I oversimplified the code for the sake of clarity: I actually have a controller
, a handler
service performing the request and a Repository
returning the query response.
Back straight to the problem: this implies that PHP must hold that big amount of data in memory and I was wondering if there was an lighter way to return the response in order to stress less PHP engine with big amount of data.
