--------------------------------------
Assignee: Joe McDonnell
> Split out service queue time from RpcRecvrTime
> ----------------------------------------------
>
> Key: IMPALA-14926
> URL: https://issues.apache.org/jira/browse/IMPALA-14926
> Project: IMPALA
> Issue Type: Task
> Components: Backend
> Affects Versions: Impala 5.0.0
> Reporter: Joe McDonnell
> Assignee: Joe McDonnell
> Priority: Major
>
> KrpcDataStreamSender keeps track of the total time for an RPC as well as the
> time spent by the receiver. It uses the difference to compute the network
> time. Right now, the receiver time covers all the time from the creation of
> the InboundCall in the reactor thread to submitting the response. Inside
> KRPC, this is actually treated as two different periods of time. The incoming
> queue time tracks the time from the creation of the inbound call to when a
> service thread picks it off of the service queue. The handler time tracks the
> time from starting work to submitting the response.
> It would be useful to keep these separately for KrpcDataStreamSender to be
> able to tell whether the receiver thread is actually taking a long time or if
> the RPC took time in the service queue.
