no-no, no problem on this end.
I know how to make the code take any number of columns into account - that's pretty easy.
I also know where the scalability issue is - it's doing the full table scan of the already cached rows.
The problem is I cannot think of an easy and non-convoluted way of fixing this....
Sorry....

curl_multi_add_handle
curl_multi_add_handle(3) libcurl Manual curl_multi_add_handle(3)
NAME
curl_multi_add_handle - add an easy handle to a multi session
SYNOPSIS
#include <curl/curl.h>
CURLMcode curl_multi_add_handle(CURLM *multi_handle, CURL *easy_handle);
DESCRIPTION
Adds a standard easy handle to the multi stack. This function call will make this multi_handle control the specified easy_handle. Further-
more, libcurl now initiates the connection associated with the specified easy_handle.
When an easy handle has been added to a multi stack, you can not and you must not use curl_easy_perform(3) on that handle!
If the easy handle is not set to use a shared (CURLOPT_SHARE) or global DNS cache (CURLOPT_DNS_USE_GLOBAL_CACHE), it will be made to use
the DNS cache that is shared between all easy handles within the multi handle when curl_multi_add_handle(3) is called.
The easy handle will remain added until you remove it again with curl_multi_remove_handle(3). You should remove the easy handle from the
multi stack before you terminate first the easy handle and then the multi handle:
1 - curl_multi_remove_handle(3)
2 - curl_easy_cleanup(3)
3 - curl_multi_cleanup(3)
RETURN VALUE
CURLMcode type, general libcurl multi interface error code.
SEE ALSO
curl_multi_cleanup(3),curl_multi_init(3)
