Do those limiters apply only to external requests or also to internal requests to shards?
Killing a request to a shard kills the whole request, so it has a magnified effect, probably larger than intended. That is why I suggested using nginx to limit request rates before they hit the cluster. That is more predictable. wunder Walter Underwood wun...@wunderwood.org <mailto:wun...@wunderwood.org> http://observer.wunderwood.org/ (my blog) > On Nov 16, 2022, at 3:55 AM, Jan Høydahl <jan....@cominvent.com > <mailto:jan....@cominvent.com>> wrote: > > Also see the Ref Guide about Request Rate Limiting: > https://solr.apache.org/guide/solr/latest/deployment-guide/rate-limiters.html > <https://solr.apache.org/guide/solr/latest/deployment-guide/rate-limiters.html> > > Jan > >> 15. nov. 2022 kl. 12:49 skrev DAVID MARTIN NIETO <dmart...@viewnext.com >> <mailto:dmart...@viewnext.com>>: >> >> hello solr users >> >> We have a production cluster of six machines using solr 8.2 and I had a >> question about whether or not changing the number of shards could improve >> the performance of collection queries.
