[jira] [Created] (IGNITE-12023) [ML] Add spatial indices support into KNN algorithm

---------------------------------------

             Summary: [ML] Add spatial indices support into KNN algorithm
                 Key: IGNITE-12023
                 URL: https://issues.apache.org/jira/browse/IGNITE-12023
             Project: Ignite
          Issue Type: Improvement
          Components: ml
            Reporter: Anton Dmitriev
            Assignee: Anton Dmitriev
             Fix For: 2.8


Currently, KNN algorithm makes a prediction using a linear scan of the date on each partition. It can take a long time in case we have a lot of data. Spatial indices such as KD tree and Ball tree can help to eliminate this problem by reducing asymptotic time to the logarithm.
