> After tackling the general k-Nearest Neighbor model as per https://issues.apache.org/jira/browse/SPARK-2335 , there's an opportunity to also offer approximate k-Nearest Neighbor. A promising approach would involve building a kd-tree variant within from each partition, a la

> This could offer a simple non-linear ML model that can label new data with much lower latency than the plain-vanilla kNN versions.
