    Description

      A common operation for multi-dimensional vectors is to find k nearest vectors to the given one.
      This task is about implementing indexes that allow to do it fast.

      • ideally they'll be engine independent
      • indexes should be update-able
      • in this task we'll only do Euclidean distance
      • we'll benchmark it on real multi-million-rows data sets
      • what algorithm, exactly, to use is still unclear
