Description
Hello,
i am trying to download and upload files from S3 to local filesystem and vice versa using Knp Gaufrette in a Symfony project.
My code work run on a container in openshift and work fine for little files but with large file (1Go) i have memory issues. I am limited to 1,5Go in my container. I don't understand why my memory is growing so high. Maybe i don't understand well the concept of stream in php but i thought that the file wasn't loaded in memory with stream but loaded chunk by chunk.
With my code i can see that when i do $srcStream = $this->fs_s3->createStream($filename); $srcStream->open(new StreamMode('rb+')); my memory is growing with the size of the file.
I also tried copy('gaufrette://s3/'.$filename,'gaufrette://nfs/'.$filename); but is is the same.
Am i using stream in the wrong way? Any advice?
Thank you in advance for your help.
Regards
