I would say at first sight that it's due to your usage of char[] and

I recommend you read and take a look at the benchmark sub-library [1]
of archery and how it's glued [2]. You will need to implement:

how do we handle NullType -> UnionType cast conversion? Do we

Hello Yue,
FeatherV2 is just a facade for the Arrow IPC file format. You can find

If you configured CMake to build tests (-DARROW_BUILD_TESTS=ON) and
install locally, there should be a `libarrow_testing.so` that you need

We should aim to improve the performance of the most widely used

platforms). AFAIK, both pip (manywheel) and conda use gcc on Linux by

As Antoine said, debug mode is probably the most important

to debug the optimized code. I'd also add the following:
