Summary: [C++][FlightRPC] Benchmark compression with real data
Key: ARROW-12581
URL: https://issues.apache.org/jira/browse/ARROW-12581
Project: Apache Arrow
Issue Type: Improvement
Components: C++, FlightRPC
Reporter: Yibo Cai
Flight benchmark program is using random test data as payload. Random data is
hard to compress. Per my test, the compressed payload (zstd default level) is
actually a bit larger than the original uncompressed payload. So compression is
a pure loss in current benchmark.
It's better to use real world test set for a more reasonable benchmark about
how compression influences FlightRPC performance. Perhaps the benchmark (both
client/server) could accept a path to an IPC file as an option.
