>
> The current implementation of call restful api is using a local libcurl handle, which means every time there is restful call, this handle will be initialized and user, after the restful call, this handle is finalized.
> Establishing the call consumes more time, we can reduce this by keep the libcurl as a long-live connection.
> A better way is to make this libcurl context as a global structure. Just initialize it once before QD calls restful api, and finalize it before QD exits.
