-------------------------------------
Summary: [C++] Use simd to improve BYTE_STREAM_SPLIT encoding
performance
Key: PARQUET-1786
URL: https://issues.apache.org/jira/browse/PARQUET-1786
Project: Parquet
Issue Type: Improvement
Reporter: Martin Radev
Assignee: Martin Radev
BYTE_STREAM_SPLIT essentially does a scatter/gather operation in the
encode/decoder paths. Unfortunately, it is not as fast as memcpy when the data
is cached. That can be improved through using simd intrinsics.
