-------------------------------------
Summary: Add targeted perf tests for CHAR
Key: IMPALA-8402
URL: https://issues.apache.org/jira/browse/IMPALA-8402
Project: IMPALA
Issue Type: Improvement
Components: Infrastructure
Reporter: Tim Armstrong
This is follow-on from IMPALA-7331. We don't currently have targeted perf
coverage for CHAR as a result of not having any CHAR-type columns in TPC-H or
TPC-DS.
CHAR is not a preferred data tyandpe in Impala because of the "interesting"
space-padding semantics and limited codegen support but people do use it in
production. It would be nice to have a way to measure perf regressions or take
credit for perf wins if/when we enabled codegen for it.
