Hi, Speaking of the computational kernels I found that Cast needs significant improvement. Right now it can not cast a FixedSizeBinary array to a Binary one which caused my ORC tests to be unusually long. I plan to significantly expand it within 2 months to include nested types and make ORC (an

Hello! I am trying to use the expression and compute APIs for query processing, and in my searches so far, this thread seems to be the most relevant. A lot of the operators and functions that I need in the short-term appear to be implemented, but the documentation seems sparse or at least not all

One objective of the precompiled kernels project is to have meaningful computational functionality in a package that does not need to include the LLVM runtime -- to require the LLVM dependency even for simple functions would more than double the size of our Python packages, for example. There is c

Hi, There are some computations kernels in arrow and it looks that this part is in active development right now. I wonder if there is a document / some emails describing what is the goal and uses cases for this part of the code base. Would be very interesting to know a bit more and I would like to
