This change is landing with #175
We added benchmarks to estimate the impact of the change. While those are local benchmark which may not reflect the behavior of all applications depending on these APIs, they illustrate the qualities and opportunities of the changes made to the parquet.RowReader and parquet.RowWriter interfaces:
name old time/op new time/op delta
BufferReadRows100x 1.67µs ± 1% 0.87µs ± 0% -48.21% (p=0.000 n=10+8)
name old row/s new row/s delta
BufferReadRows100x 59.8M ± 0% 115.4M ± 0% +92.95% (p=0.000 n=9+8)
name old time/op new time/op delta
BufferWriteRows100x 3.79µs ± 0% 1.41µs ± 0% -62.82% (p=0.000 n=9+9)
name old row/s new row/s delta
BufferWriteRows100x 26.4M ± 0% 70.9M ± 0% +168.93% (p=0.000 n=9+9)
