> Add support for cosine similarity function
> ------------------------------------------
>
> Key: IMPALA-14566
> URL: https://issues.apache.org/jira/browse/IMPALA-14566
> Project: IMPALA
> Issue Type: Task
> Reporter: Abhishek Rawat
> Assignee: Raghav Jindal
> Priority: Major
>
> The cosine similarity function measures the angle between two vectors,
> regardless of their length (magnitude). The use cases include measuring text
> similarity and is ideal when the direction (semantic meaning/concept) is more
> important than the magnitude.
> Impala doesn't support a native vector data type yet, so we could possibly
> use an ARRAY<FLOAT> data type for representing vectors.
