Noble Paul commented on SOLR-10105:
-----------------------------------
It's not a good idea to move any part of streaming expression to core. It
should work anywhere outside solr
> JDBCStream should be able to load driver from runtime lib

> Currently the JDBCStream uses Class.forName() to load the driver class. This
> should be improved to try to use the classloader from runtimeLib and the blob
> store API like SOLR-10087. It may be possible to do something like
> Class.forName(driverClassName, true, core.getMemClassLoader()) just need to
> figure out how to get a reference to the core.
