Re: Unloading and loading a Collection in SolrCloud with external Zookeeper ensemble
Hi Erick, thanks for the reply. I am working on a application where a solr collection is being created per usage of application accumulating lot of them over period of time . In order to keep memory requirements under control, I am unloading collections not in current usage and loading them whenever required. This was working in non cloud mode with coreAdmin APIs. Now because of scaling requirements we want to shift to SolrCloud mode. we want to continue with same application design. can you suggest, how to implement a similar solution in SolrCloud context. -Gajanan -- Sent from: https://lucene.472066.n3.nabble.com/Solr-User-f472068.html
Re: Unloading and loading a Collection in SolrCloud with external Zookeeper ensemble
I don’t really have any good alternatives. There’s an open JIRA for this, see: SOLR-6399 This would be a pretty big chunk of work, which is one of the reasons this JIRA has languished… Sorry I can’t be more helpful, Erick > On Nov 15, 2020, at 11:00 AM, Gajanan wrote: > > Hi Erick, thanks for the reply. > I am working on a application where a solr collection is being created per > usage of application accumulating lot of them over period of time .

Re: Unloading and loading a Collection in SolrCloud with external Zookeeper ensemble
An unelegant alternative is to back up and delete a collection in lieu of unload, restore it in lieu of load...

Re: Unloading and loading a Collection in SolrCloud with external Zookeeper ensemble
Thanks for the replies. Wanted to make sure that I am not missing on something already available. Now that everything is clear, I may have to go for application re-design or choose an approach, not so elegant, as suggested. Thanks all. -Gajanan -- Sent from: https://lucene.472066.n3.nabble.com/Solr-User-f472068.html
