Summary: Add memset Stream Evaluator
Key: SOLR-12159
URL: https://issues.apache.org/jira/browse/SOLR-12159
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Joel Bernstein
The *memset* function will set multiple numeric arrays from fields in an
underlying TupleStream. This will be much more memory efficient then calling
*col* function multiple times on an in memory list of Tuples. Sample syntax:
{code:java}
let(a=memset(copy="field1, field2",
vars="c, d",
random(collection1, q="*:*", fl="field1, field2", rows=50000)),
e=corr(c, d))
{code}
