Expand description
Cross-instance hash repartition for distributed GROUP BY. Gated on
cluster-unstable because it pulls in the shuffle transport.
Cross-instance hash repartition. Replaces DataFusion’s in-process
RepartitionExec::Hash between AggregateExec::Partial and
AggregateExec::FinalPartitioned. One output partition per owned
vnode; remote rows ship via ShuffleSender.
