I kind of solve the case regarding this thread >> https://community.appeon.com/index.php/qna/q-a/upload-files-to-a-web-service

The solution I found was to split the file in parts of 1MB (Byte array supports this number of rows). Then, this parts are sent to the Web Service and then it puts all them together again.

In the client

err = f_read_file ( "test.zip" , lbyte_part_1[] , lbyte_part_2[] , lbyte_part_3[] ) 

In the WS

lbl_file = abl_part_1

If Len ( abl_part_2 ) <> 0 Then lbl_file += abl_part_2

If Len ( abl_part_3 ) <> 0 Then lbl_file += abl_part_3

err = f_write_file ( "receive.zip" , lbl_file ) 

I just wanted to share it.

Regards

Hi Julián;

  Thanks for the great tip!   yes

Looks like another approach of what I call "data chunking" when I did this to solve uploading super large DB Blob column data. How did this approach change the web service upload performance when compared to smaller files that you were able to directly upload before changing your code?

Regards ... Chris

Hi Chris,



Well at the moment all tests are performed inside our LAN. The next step is to test it in a real scenario. I will let you know.



Regards
