Bikramjeet Vig commented on IMPALA-7351:
----------------------------------------
All of the missing estimates seem to be covered now except for the
PlanRootSink. I am deferring that to IMPALA-4268 since that can change the mem
requirement.
> Add memory estimates for plan nodes and sinks with missing estimates

>
> Many plan nodes and sinks, e.g. KuduScanNode, KuduTableSink, ExchangeNode,
> etc are missing memory estimates entirely.
> We should add a basic estimate for all these cases based on experiments and
> data from real workloads. In some cases 0 may be the right estimate (e.g. for
> streaming nodes like SelectNode that just pass through data) but we should
> remove TODOs and document the reasoning in those cases.
