Subject Re: Arrow C# bindings
Date Mon, 05 Jun 2017 10:32:45 GMT
We have some benchmarks that test parts of the Arrow C++ library, e.g. https://github.com/apache/arrow/blob/master/cpp/src/arrow/builder-benchmark.cc
and https://github.com/apache/arrow/blob/master/cpp/src/arrow/jemalloc/jemalloc-builder-benchmark.cc
. These are only in the C++ part as the Java library provides different facilities to construct
the Arrow arrays. As the core of Arrow are its data structures, it is probably better to benchmark
the C++/Java libraries when used in the same use case, e.g. reading Parquet files, but in
different languages. Then you should see if there are notable differences.
