We'll take all these into consideration in order to size and simulate both
indexing and search flow in load.
Thanks again,

Erick - thanks a lot for answering and sharing the below article, it's very

I have another follow-up question - assuming we have 400 vCPUs across our
SolrCloud cluster nodes, will it be better to have 400 shards with replication
factor 2
or
What utilizes better the CPUs -
shards/or their replicas ?

Yes, I’m exactly talking about the idea of someone pu
queries and lower QPS ?

actually cause delays in queries and lower QPS ?

Hi Furkan,
Thanks for your response !

Hi Adi,
RAID10 is good for satisfying both indexing and query, striping across
mirror sets. However, you lose half of your raw disk space, just like with
RAID1.
Here is a mail thread of mine which discusses RAID levels for Solr
specific:

Hi,
We are about to size large environment with 7 nodes/servers with replication
factor 2 of SolrCloud cluster (using Solr 7.6).
The system contains parent-child (nested documents) schema, and about to have
40M parent docs with 50-80 child docs each (in total 2-3.2B Solr docs).
We have a use ca
