Re: Solr Cloud + zookeeper+ kubernetes setup

There’s a fundamental downside of embedded zk or putting zk on the same node as Solr. When there are many queries running, a Solr replica gets overloaded and it starts to affect the node itself (sometimes you can’t even ssh into the node when Solr is too busy), it also affects the Zk on the same

Hi Vince, Here's a tutorial for installing an external ZK + Solr on k8s: https://sematext.com/blog/solr-operator-autoscaling-tutorial/ Hope it helps. Radu -- Elasticsearch/OpenSearch & Solr Consulting, Production Support & Training Sematext Cloud - Full Stack Observability https://sematext.com/

Re: Solr Cloud + zookeeper+ kubernetes setup

**NOW** In a k8s setting, ZK will have separate PODs (with both the suggested helm charts), and a POD hooks into the linux kernel to guarantee some resources so it is not starvated by hot Solr PODs on the same k8s node. So no need for separate machine, separate POD is ok. **FUTURE, NOT EXISTIN

Thank you for the prompt response guys! Apart from this case, I've encountered other problems that are peculiar to the v2 API in 9.4. 1. Creating a backup [1] request using the v2 api directives sporadically returns `An exception was not mapped due to exception mapper failure. The HTTP 500 respon

Pb between pod and replicas

Hello, I have a problem with SolrCloud (8.11.1). Normally, each K8S pod hosts a replica. However, during installation (or reinstallation) it happens that a pod recovers 2 replicas and that another pod does not recover any. We fix this with the admin console. However, when restarting the pod, we f

Thanks, Moriyasu for the heads up! I'll advertise it on my LinkedIn soon and on the Apache Solr Twitter account! Also contacted some of the Japanese people I know to get better engagement :) Cheers -- *Alessandro Benedetti* Director @ Sease Ltd. *Apache Lucene/Solr Committe

Re: Solr Cloud + zookeeper+ kubernetes setup

In k8s it’s quite simple already. But if the SIP is done there will be similar operational benefits for manual installs as well. But I would not hold my breath, may never happen. Jan Høydahl > 23. nov. 2023 kl. 18:50 skrev Dmitri Maziuk : > > On 11/23/23 04:59, Jan Høydahl wrote: > >> **FUTU
