Re: Correct Procedure for making Basic Authentication Changes LIVE across Multiple Nodes in Solr Cloud 8.10

I imagine if you could afford to shut down all the running Solr instances for a small amount of time, you could shut them all down, make the auth changes, and start them all at the same time --ufuk yilmaz From: Jan Høydahl Sent: Thursday, December 28, 2023 3:20

Re: SolrCloud availability when a server is down

If your backend is in Java, SolrJ can do the same too. You instantiate a SolrJ instance using the zookeeper URL instead of a specific Solr node url, and it keeps itself in sync with live nodes list and forwards requests to whichever node is alive From: Rigolin, D

Re: SOLR data on ECS problem with write lock files

Hello Darren, I had a very similar problem when running Solr on EKS kubernetes cluster. The solution I found was to add a pre_stop shutdown hook to the kubernetes deployment, which runs the command "/opt/solr/bin/solr stop -k solrrocks -p 8983" to gracefully stop Solr before the pod is killed.

Re: ML Model Management in Solr

There's a way to produce, use and store them but it only supports a fixed format: https://solr.apache.org/guide/8_5/stream-source-reference.html#model https://solr.apache.org/guide/8_5/stream-source-reference.html#train https://solr.apache.org/guide/8_5/stream-decorator-reference.html#classify m

Optimizing Solr for low memory

Is there a general guideline to optimize Solr for very little number of documents in the core and low memory? For example, let's say 2000 documents and 100mb of memory. It crashes often due to OOM error with the default configuration. Are there places in the Solr config where we can look to mak

Re: Configuring/reconfiguring k8s SolrCloud cluster GitOps way

Hi! For uploading the scripts from inside the image, I didn't implement a locking mechanism or assigned an instance 🤔 Since if configset was already uploaded on the first ever run, on the subsequent runs it would just log an error (configset already exists) and continue with the rest of the proc

Re: Group by query reports null pointer when unique key is not stored

I also got this exception before and in order to avoid reindexing TB's of data, had to resort to grouping via streaming expressions, which has its ups and downs. If it's technically infeasible to substitute docValues for this purpose (when useDocValuesAsStored:true), it would be nice if it was d

Re: Apache Solr Query Issue with huge data

Hi, Solr usually fills the heap with various caches so I wouldn't worry much about it consuming %90 of the heap, unless I get OutOfMemory errors. Pagination using rows parameter is intended for when row count is very low and page number is also small (eg. rows=10 page=2 etc.). It's problematic

Re: Date syntax : Filter by month independent of the year

also if your index is a bit large, invest in an architecture which makes reindexing very easy, as you will probably need to change the schema and reindex multiple times --ufuk yilmaz From: Walter Underwood Sent: Friday, April 5, 2024 8:59 PM To: users@solr.apach
