We have found that the gRPC mailbox mechanism penalizes the first MSE query that arrives after 30 minutes of inactivity. This is because by default, gPRC connections move to the idle state after 30 minutes of inactivity, and it is especially noticeable when these connections require establishing TLS connections. AFAIK it is not possible to configure gRPC. Instead, I'm adding a new scheduled task that sends a ping to each known participant. I'm also setting the idle timeout to twice the period used for pings. This feature can be disabled by setting the new config `pinot.query.runner.pinger.frequency.seconds` to 0 or negative. -- This is an automated message from the Apache Git Service.
