solr cloud vs standalone solr

[sara hajili <ha...@gmail.com>]

hi all,
I want to know when standalone solr can't be sufficient for storing data
and we need to migrate to solr cloud?for example standalone solr take too
much time to return query result or to store document or etc.

in other word ,what is best capacity and data index size in  standalone
solr  that doesn't bad effect on query running and data inserting
performance?and after passing this index size i must switch to solr cloud?

There is no solid rule. Honestly stand alone solr can handle quite a bit, I don't think there's a valid reason to go to cloud unless you are starting from scratch and want to use the newest buzz word, stand alone can handle well over half a terabyte index at sub second speeds all day long.

This is a variant of "the sizing question", here's the long
explanation of why there's no hard rule as Aman says:

https://lucidworks.com/2012/07/23/sizing-hardware-in-the-abstract-why-we-dont-have-a-definitive-answer/

One variant of your question is "when do you have to shard a
collection". SolrCloud is not _required_ to shard a collection, it
just makes it _much_ easier to manage (I'd go farther and say the
circumstances must be extraordinary to shard and _not_ use SolrCloud).

Assuming you do not need to shard (measured by getting adequate
response time for a "reasonable" query rate) but you need to serve
more queries per second, you have two choices:

- older style master/slave replication so two or more copies of your
index are serving queries
- use SolrCloud with a single shard collection.

This latter has some advantages in terms of administration, HA/DR etc.
at the expense of added complexity for managing your ZooKeeper
ensemble.

Best,
Erick

Hello Sara,

There is hard n fast rule, performance depends on caches, RAM, hdd etc.and
how much resourced you could invest to keep the acceptable performance.
Information on Number of Indexed documents, number of dynamic fields can be
viewed from the below link. I hope this helps.
