-----------------------------------
Summary: [C++] Create many-column scanner microbenchmarks
Key: ARROW-18387
URL: https://issues.apache.org/jira/browse/ARROW-18387
Project: Apache Arrow
Issue Type: Sub-task
Components: C++
Reporter: Weston Pace
When developing we often assume schemas are cheap and small only to find out
later that we create easily avoided bottlenecks for users that have very large
schemas. We should create some micro-benchmarks for the scanner that verify we
get roughly the same performance, in data-bytes-per-second, with many-columns
as we do with few-columns (note, that we probably suffer in rows-per-second
since we are loading more columns and thus more data).
This might also be a good time to create similar benchmarks for dataset
discovery.
