-------------------------------------
Summary: Implement dot-product in a compute kernel
Key: ARROW-11115
URL: https://issues.apache.org/jira/browse/ARROW-11115
Project: Apache Arrow
Issue Type: New Feature
Components: Rust
Reporter: Erik De Smedt
An efficient implementation of the
[dot-product|https://en.wikipedia.org/wiki/Dot_product] is useful for many
machine-learning applications.
I would propose to treat null as zero for the implementation. This behavior is
sensible because it corresponds to dropping any observation where null-data is
present.
