> Priority: Major
> Labels: performance
> Fix For: Impala 5.1.0

>
> Currently channels can have a single in-flight batch + another batch for
> serialization of incoming rows. There is no way to hold ready-to-send batches
> that are net yet passed to krpc. Adding some capacity for ready-to-send
> batches would help to mitigate temporary slowness in some receivers by
> letting keeping batches for that receiver in memory while others could
> progress.
> wip implementation: https://gerrit.cloudera.org/#/c/21579/
