Re: Massively unbalanced CPU by different SOLR Nodes

Hi Shalin, Moving to 8.6.3 fixed it! Thank you very much for that. :) We'd considered an upgrade - just because - but we won't have done so so quickly without your information. Cheers On Sat, Oct 24, 2020 at 11:37 PM Shalin Shekhar Mangar < shalinman...@gmail.com> wrote: > Hi Jonathan, > > Are

Duplicate entries for request handlers in Solr metric reporter

Hi, I have hooked up Grafana dashboards with Solr 8.5.2 Prometheus exporter. For some reason, some dashboards like Requests, Timeouts are not showing any data. When I took a look at corresponding data from Prometheus exporter, it showed two entries per search request handler, first with count of 0

disallowing delete through security.json

I am interested in disallowing delete through security.json After seeing the "method" section in lucene.apache.org/solr/guide/8_4/rule-based-authorization-plugin.html my first attempt was as follows: {"set-permission":{ "name":"NO_delete", "path":["/update/*","/update"], "collection":col_name,

Question on solr metrics

Can we get the metrics for a particular time range? I know metrics history was not enabled, so that I will be having only from when the solr node is up and running last time, but even from it can we do a data range like for example on to see CPU usage on a particular time range? Note: Solr version

List Collections API output as CSV causes NullPointerException

I'm trying to get a simple text listing of my collections (so that I can do some shell scripting loops [for example calling SOLR Cloud Backup on each]). I'm getting an exception when I simply append the "&wt=csv" to the end of the collection's LIST api (eg: http://localhost:8983/solr/admin/co

Re: Performance issues with CursorMark

8.6 still has uninvertible=true, so this should go ahead and create an on-heap docValues structure. That’s going to consume 38M ints to the heap. Still, that shouldn’t require 500M additional space, and this would have been happening in your old system anyway so I’m at a loss to explain… Unless

Re: Question on metric values

The “requests” metric is a simple counter. Please see the documentation in the Reference Guide on the available metrics and their meaning. This counter is initialised when the replica starts up, and it’s not persisted (so if you restart this Solr node it will reset to 0). If by “frequency” you

RE: Performance issues with CursorMark

Hello Anshum, Good point! We sort on the collection's uniqueKey, our id field and this one does not have docValues enabled for it. It could be a contender but is it the problem? I cannot easily test it at this scale. Thanks, Markus -Original message- > From:Anshum Gupta > Sent: Monda

Question on metric values

I am new to metrics api in solr , when I try to do solr/admin/metrics?prefix=QUERY./select.requests its throwing numbers against each collection that I have, I can understand those are the requests coming in against each collection, but for how much frequencies?? Like are those numbers from the tim

Re: Performance issues with CursorMark

Hey Markus, What are you sorting on? Do you have docValues enabled on the sort field ? On Mon, Oct 26, 2020 at 5:36 AM Markus Jelsma wrote: > Hello, > > We have been using a simple Python tool for a long time that eases > movement of data between Solr collections, it uses CursorMark to fetch >

Re: TieredMergePolicyFactory question

Thanks Shawn and Erick. So far I haven't noticed any performance issues before and after the change. My concern all along is COST. We could have left the configuration as is - keeping the deleting documents in the index - But we have to scale up our Solr cluster. This will double our Solr Cluste

Re: json.facet floods the filterCache

Damien, I gathered that you're using "nested facet"; but there are a lot of different ways to do that, with different implications. e.g., nesting terms facet within terms facet, query facet within terms, terms within query, different stats, sorting, overrequest/overrefine (and for that matter, refi

Re: TieredMergePolicyFactory question

"Some large segments were merged into 12GB segments and deleted documents were physically removed.” and “So with the current natural merge strategy, I need to update solrconfig.xml and increase the maxMergedSegmentMB often" I strongly recommend you do not continue down this path. You’re making a m

Performance issues with CursorMark

Hello, We have been using a simple Python tool for a long time that eases movement of data between Solr collections, it uses CursorMark to fetch small or large pieces of data. Recently it stopped working when moving data from a production collection to my local machine for testing, the Solr nod

According to the source code here https://github.com/apache/lucene-solr/blob/releases/lucene-solr/8.6.2/solr/core/src/java/org/apache/solr/core/SolrPaths.java#L134 your allowPaths value is NOT equal to «*» (which is stored as _ALL_) (parsed here https://github.com/apache/lucene-solr/blob/releas
