> URL: https://issues.apache.org/jira/browse/SOLR-12198
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Joel Bernstein
> Assignee: Joel Bernstein
> Priority: Major
> Fix For: 7.4

>
> Currently many of the Stream Evaluators that are working with matrices are
> creating multiple copies of the underlying multi-dimensional arrays. This can
> lead to excessive memory usage. This ticket will change the implementations
> so copies of the multi-dimensional arrays that back a matrix are only copied
> when the *copyOf* function is used.
