-----------------------------------
Labels: pull-request-available (was: )
> [C++] Create more benchmarks for measuring expression evaluation overhead
> -------------------------------------------------------------------------
>
> Key: ARROW-16014
> URL: https://issues.apache.org/jira/browse/ARROW-16014
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Weston Pace
> Assignee: Sanjiban Sengupta
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> We have a lot of great benchmarks on individual kernels but I don't know if
> we have enough benchmarks on the function & expression evaluation itself.
> There are some benchmarks (function_benchmark.cc) which measure this but I
> would like to get a better sense of a "bytes per second" number from the
> function system for a trivial function (e.g. an identity function that simply
> returns the values as is).
> In addition, we should measure overhead for common tasks like preallocation,
> etc.
> I would also like these benchmarks to be parameterized by batch size. Being
> able to run on small batches enables (in theory) better cache utilization. I
> suspect that the overhead here may start to become a bottleneck.
