Summary: Add support for euclidean distance function
Key: IMPALA-14572
URL: https://issues.apache.org/jira/browse/IMPALA-14572
Project: IMPALA
Issue Type: Task
Reporter: Abhishek Rawat
The euclidean distance (L2) could be used sometimes when the magnitude of the
vector (e.g., the frequency or intensity of a feature) is an important
indicator of similarity. As an example to find similar houses based on sqFt, #
bedrooms, price, etc., euclidean distance can provide better similarity results.
Impala doesn't support a native vector data type yet, so we could possibly use
an ARRAY<FLOAT> data type for representing vectors.
