Kevin Risden commented on SOLR-10086:
-------------------------------------

So I'm not 100% sure that adding the Kafka dependencies to Solr would be the 
right approach. I was chatting with [~joel.bernstein] earlier and was wondering 
if its possible to load custom streaming expressions. They can be registered 
(see SOLR-9103) in solrconfig.xml as long as the jar is on the classpath. 

Another option that I just tried out was registering jars via the blob store 
and then registering the custom streaming expression. I put together an example 
of this here: https://github.com/risdenk/solr_custom_streaming_expressions

This requires a change to the StreamHandler class currently. See SOLR-10087

> This is being asked to have SolrCloud pull data from Kafka topic periodically 
> using DataImport Handler. 
> Adding streaming expression support to pull data from Kafka would be good 
> feature to have.
