This benchmark benchmarks writing 10 batches (rather than the original benchmark from @andygrove that did both 1 and 10 batches). I profiled them both and the actual encoding of batches far dwarfs the writer creation time so I thought it would be best to focus on just writing

let mut group = c.benchmark_group("arrow_ipc_stream_writer");

group.bench_function("StreamWriter/write_10", |b| {
let batch = create_batch(8192, true);
let mut buffer = Vec::with_capacity(2 * 1024 * 1024);
b.iter(move || {
buffer.clear();
let mut writer = StreamWriter::try_new(&mut buffer, batch.schema().as_ref()).unwrap();
for _ in 0..10 {
writer.write(&batch).unwrap();
}
writer.finish().unwrap();
})
});

group.bench_function("StreamWriter/write_10/zstd", |b| {
let batch = create_batch(8192, true);
let mut buffer = Vec::with_capacity(2 * 1024 * 1024);
b.iter(move || {
buffer.clear();
let options = IpcWriteOptions::default()
.try_with_compression(Some(CompressionType::ZSTD))
.unwrap();
let mut writer =
StreamWriter::try_new_with_options(&mut buffer, batch.schema().as_ref(), options)
.unwrap();
for _ in 0..10 {
writer.write(&batch).unwrap();
}
writer.finish().unwrap();
})
});

group.bench_function("FileWriter/write_10", |b| {
let batch = create_batch(8192, true);
let mut buffer = Vec::with_capacity(2 * 1024 * 1024);
b.iter(move || {
buffer.clear();
let mut writer = FileWriter::try_new(&mut buffer, batch.schema().as_ref()).unwrap();
for _ in 0..10 {
writer.write(&batch).unwrap();
}
writer.finish().unwrap();
