We are using a HTTP enabled malware scanning service based on Clam AV.

The service is made something like this

We have files like CAD files which can go in GBs and want to send to this malware scanning service.

Is there a possibility to send the file in chunks and get it scanned in the server side in chunks.

I observed that there is a INSTREAM command in clamd for this purpose and also there is a 4GB size limit.

Read somewhere the full file size is mapped to memory. Is it the case for INSTREAM command also ?

If it is the case then even if chunking is supported then the server side must have at least 4GB of memory.

Best Regards,
