---------------------------------------
[~bikramjeet.vig] can we close this now?
> Add memory estimates for plan nodes and sinks with missing estimates

> Key: IMPALA-7351
> URL: https://issues.apache.org/jira/browse/IMPALA-7351
> Project: IMPALA
> Issue Type: Sub-task
> Components: Frontend
> Reporter: Tim Armstrong
> Assignee: Bikramjeet Vig
> Priority: Major
> Labels: admission-control, resource-management
>
> 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.
