--------------------------------------
Summary: [Docs][C++] Guide to to work with RLE data (in kernels?)
Key: ARROW-17029
URL: https://issues.apache.org/jira/browse/ARROW-17029
Project: Apache Arrow
Issue Type: Sub-task
Components: C++, Documentation
Reporter: Tobias Zagorni
Topics I can think of right now: * introducing some utility functions for
working with RLE data that I'm collecting currently as rle_util.h on my filter
branch
* how physical/logical indices work, especially in combination with arrow
offsets
* how common kinds of kernels can be converted to RLE. E.g scalar kernels with
a single input could automatically be run on the internal data array of RLE.
Scalar with multiple inputs and some kinds of vector algorithms should use
