1. I never saw the poll. 2. It looks better than the previous poll, which was poorly worded. I couldn’t answer “yes” or “no”, really.
Here is what we have in production. Solr 3: Using every threat I can think of to get the remaining clients off of it. It has been shut down in test for months. Solr 4 master/slave: Main cluster for smallish (under 1Mdoc) collections with daily updates, plus one that needs to move to… Solr 6 cloud: Hosts one small collection with strong freshness requirements and one large collection with very difficult queries. The second is mid-transition from the Solr 4 cluster. There is no reason to go to Solr Cloud for a moderate size collection with daily update. None. The loose coupling makes scaling out trivial, just spin up an exact duplicate of an existing slave. No ADDREPLICA commands or trying to understand how core names are mapped to node names and then to host names (drives me nuts). Same thing for scaling back, take it out of the load balancer and shoot it. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) > On Apr 25, 2017, at 9:23 AM, Erick Erickson <erickerick...@gmail.com> wrote: > > Maybe the other thing in play here is that use-cases that "just work" > in the master/slave environment are less likely to employ consultants > so we get something of a skewed sense of who uses what ;) > > On Tue, Apr 25, 2017 at 1:50 AM, Charlie Hull <char...@flax.co.uk> wrote: >> On 24/04/2017 15:58, Otis Gospodnetić wrote: >>> >>> Hi, >>> >>> I'm really really surprised here.
