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 :
