[jira] [Created] (ARROW-11115) Implement dot-product in a compute kernel

Erik De Smedt created ARROW-11115:
-------------------------------------

             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.
