It would be useful for a proxy method to notify the handler to not yet the send the call's response. > An potential use case is a namespace handler in the NN might want to return before the edit log is synced so it can service more requests and allow increased batching of edits per sync. Background syncing could later trigger the sending of the call response to the client. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
