@hvanhovell Yes I will. I'm trying to get a stable base benchmark first as
running the ParquetReadBenchmark repeatedly against the base code (before
either PR) I get what looks like a 10% variation in results. The same is true
with either of the PRs applied so I will average out the runs.
As far as subclassing goes I would expect performance on LE to remain the
same as the code path should be identical once the classes are instantiated.
Performance on BE between the 2 approaches is another thing but not the major
concern at the moment as we are going from failing/exceptions thrown to
"working"
