Subject [jira] [Updated] (SOLR-10516) Add eval() Streaming Expression
Date Tue, 18 Apr 2017 19:32:41 GMT

     [ https://issues.apache.org/jira/browse/SOLR-10516?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Joel Bernstein updated SOLR-10516:
----------------------------------
    Description: 
The eval() Streaming Expression reads a single tuple from an underlying stream and looks in
the expr_s field for an expression to compile and run. eval emits the tuples from the expression
that it compiles. 

This allows streaming expressions to write streaming expressions and have them evaluated.

Syntax:
{code}
eval(expr)
{code}

  was:
The eval() Streaming Expression reads a single tuple from an underlying stream and looks in
the expr_s field for an expression to compile and run. eval emits the tuples from expression
that it compiles. 

This allows streaming expressions to write streaming expressions and have them evaluated in
the same.
