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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
