Joel Bernstein updated SOLR-12198:
----------------------------------
Description: Currently several of the Stream Evaluators that work with
matrices are creating multiple copies of the underlying multi-dimensional
arrays. This can lead to excessive memory usage. This ticket will change these
implementations so copies of the multi-dimensional arrays that back a matrix
are only copied when the *copyOf* function is used. (was: Currently a few of
