To limit request rate, I would put an instance of nginx on each host, send external requests to that, then have that forward to Solr. Nginx has good tools for controlling request rate.
This would also give you a place to monitor the extrernal requests separate from the intra-cluster traffic. wunder Walter Underwood wun...@wunderwood.org <mailto:wun...@wunderwood.org> http://observer.wunderwood.org/ (my blog) > On Nov 15, 2022, at 3:49 AM, DAVID MARTIN NIETO <dmart...@viewnext.com > <mailto:dmart...@viewnext.com>> wrote: > > 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.
