> Currently, if user wants for example to insert 20k records they need to call {{SQLExecute}} for the 20k times. More than that, internally, we transmit and execute the same SQL query 20k times. This is a huge overhead. We should only transfer sql query once, transfer all the parameters in a batch and then execute it once using some fast, possibly internal API.
