[jira] [Updated] (SOLR-12159) Add memset Stream Evaluator
[ https://issues.apache.org/jira/browse/SOLR-12159?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Joel Bernstein updated SOLR-12159:
----------------------------------
Description:
The *memset* function will copy multiple numeric arrays into memory from fields in an underlying TupleStream. This will be much more memory efficient then calling the *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}
