Hello Sarah. It's hard to propose to stay on DIH, but fwiw, couldn't it still be deployed by placing jars into some /lib dir and cofiguring like in the good old days? I guess it still works and suits fine for custom images, where there's no need in runtime plugin deploy. Also, recently I added an ability to work in coordinator node in SolrCloud https://github.com/SearchScale/dataimporthandler/pull/62 Regarding alternatives, I looked into Apache Hop, but found it difficult to build a proper payload without a proper SolrOutputPlugin, haven't got a chance to implement it either.
