Hi everyone, I am considering moving one or several Solr clusters to production. Although Solr's documentation and community is *great*, I am strongly startled not to find any *complete use-case story* stretching from application(s) needs and data considerations to hardware ones. Indeed, I understand why "what/how much hardware / configuration / sharding" questions are systematically replied with both "it depends" followed by "test". But then, what about a few complete descriptions, out of so many elasticsearch users, from data use case to cluster's internals, along with a few performance and nodes stats?
So here are questions, before moving to production : Are there any *complete* use cases around? Could you share some? By complete I mean including *at least some* of the following : 1. *Application needs and scope* 2. *Indexing Data indications* : data volume, documents mapping, documents / indexes volume 3. *Searching Data indications* : different applications, queries, use of facets - filters - pivot facets, concurrent indexing 4. *Cluster Hardware* : machines' hardware (RAM, Disks/SSD - DAS-JBOD/SAN/NAS), JVM heap / OS Cache, nb of machines, back office network 5. *Cluster Configuration* : one or several indexes, sharding, replication, master nodes, data nodes, use of over-sharding at start-up, use of re-indexing 6. *Benchmaks *: queries response times, QPS, with or without concurrent indexing, memory heap sweet spot, nodes stats For those interested, here is the (not *complete*) best-among-very-few exemples I've stumbled upon so far : - Perfs with hardware and query description : http://fr.slideshare.net/charliejuggler/lucene-solrlondonug-meetup28nov2014-solr-es-performance
