Hello everyone, This is kind of a long-time coming, but I've finally created a SIP for autoscaling Solr Nodes on Kubernetes using the Solr Operator.
https://cwiki.apache.org/confluence/display/SOLR/SIP-17%3A+Node+Autoscaling+via+Kubernetes There are still some details that need to be ironed out, but hopefully we can finalize everything relatively soon and try to get this out in Solr 9.3/9.4 and the Solr Operator v0.8.0. I've talked with quite a few people about this, so hopefully we can get a good amount of turn-out to get this implemented! And if anyone is interested in helping with the Solr Operator parts, I'd be very happy to mentor. It's not going to be the most straightforward code, but you will definitely be ramped up on contributing to the operator by the end! Please let me know if I can answer any questions! - Houston
