Weston Pace created ARROW-18387: ----------------------------------- 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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
