Will Berkeley created IMPALA-8284:
-------------------------------------
Summary: KuduTableSink spends a lot of CPU copying
KuduColumnSchemas
Key: IMPALA-8284
URL: https://issues.apache.org/jira/browse/IMPALA-8284
Project: IMPALA
Issue Type: Improvement
Affects Versions: Impala 3.1.0
Reporter: Will Berkeley
I noticed Impala spending a significant amount of CPU time in
{{KuduTableSink::Send}} creating and destroying KuduColumnSchemas.
See KUDU-2731 for more information.
Impala could wait for a better option from the Kudu API, or could cache
information about nullability of columns outside the hot loop in Send.
