-------------------------------------
Summary: 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
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.
