----------------------------------------
Summary: [C++] Experiment to see if using SIMD shuffle operations
for DecodeSpaced improves performance
Key: PARQUET-1841
URL: https://issues.apache.org/jira/browse/PARQUET-1841
Project: Parquet
Issue Type: Improvement
Components: parquet-cpp
Reporter: Micah Kornfield
Followup from PARQUET-1840 for current benchmarks it seems that doing removing
the memset somehow either has no impact or is slightly worse. We should
investigate using SIMD operations to speed up spacing.
As part of this we can see if moving the memset to only cover uninitialized
values after moving all required values provides any speedup.
