------------------------------------
Summary: Add EvalStream to support "computing on the code" use
cases
Key: SOLR-8763
URL: https://issues.apache.org/jira/browse/SOLR-8763
Project: Solr
Issue Type: Bug
Reporter: Joel Bernstein
Streaming Expression presents interesting opportunities for "computing on the
code". The EvalStream will call toExpression() on an underlying stream and then
compile and run resulting expression. This will allow developers to write
Streaming Expressions that dynamically builds other Streaming Expressions.
This type of behavior could probably be already done in the open() method, but
having an EvalStream adds specific support for dynamic Streaming Expression
generation and should encourage these types of applications.
