From my reading the current solutions depends on Solr Autoscaling and on Horizontal Pod Autoscaler.
From Solr docs: Deprecations The autoscaling framework is now formally deprecated and will be removed in Solr 9.0. The Solr community is working on pluggable API to replace this functionality, with the goal for it to be ready by the time 9.0 is released. Deprecations include: autoscaling policy, triggers, withCollection support, simulation framework, autoscaling suggestions tab in the UI, autoAddReplicas and UTILIZENODE command. And from directions on AWS: Scaling replicas with SolrCloud autoscaling SolrCloud (version 8.x) comes with built-in autoscaling feature that allows replicas to be added or removed automatically from a pod depending on the metrics being monitored. The deployment uses a collection-level cluster policy to scale replicas. Cluster policies can also be applied at a shard or node (pod) level. You can configure SolrCloud autoscaler to track the search rate event by monitoring the requests per minute value available via the QUERY./select.requestTimes:1minRatemetric, for scaling the replicas. This metric is monitored and used to scale the number of replicas in the SolrCloud cluster. Note that there are a number of other SolrCloud metrics available via the Solr metrics API that you can consider while defining and fine-tuning replica autoscaling for the SolrCloud cluster. And it seems that the Solr Operator needs Solr Autoscaling found in v8. Is that correct? I have an opportunity to re-architect our deployment but I do not want to go to Solr 9 without K8 (Kubernetes) integration. The system is 300 JVMs, 100 shards with replication factor 3. I deploy them onto EC2 and have in house code to manage the IPs for everything and create and distribute the replicas across availability zones. Near 1 billion records, 4K Queriers per Minute, 1.5K upsets per minute that can burst to 6K upsets per minute for weeks. > On Mar 29, 2023, at 6:32 PM, Deepak Vohra <dvohr...@yahoo.com.INVALID> wrote: > > Apache Solr Operator manages Solr resources in KubernetesDoesn't it support > version 9 yet?https://solr.apache.org/operator/ > 8.6+ is listed as supported, which should include 9.2. > https://apache.github.io/solr-operator/docs/upgrade-notes.html > > On Wednesday, March 29, 2023 at 04:29:25 p.m. EDT, Phill Campbell > <sirgilli...@yahoo.com.invalid> wrote: > > I have been looking for an example of how to use Solr 9 with Kubernetes. > All of the examples I have found are using Solr 8 and Solr 8’s autoscaling. > > Since autoscaling is deprecated in Solr 9 I was hoping to find guidance for > Solr 9. > >
