Yeah, sorry, my maths was clearly flawed today, thanks for correcting me
Shawn.
What I meant was in a 3 ZK setup, if you lose one machine, you are okay,
but you are also "at risk", since losing anything else would lose quorum.
So in our NRT-style scenario, we would have to get that dead machine ba

That would NOT block indexing. If yo
Just to chip in, more ZKs are probably only necessary if you are doing NRT
indexing.
Loss of a single ZK (in a 3 machine setup) will block indexing for the time
it takes to get that machine/instance back up, however it will have less
impact on search, since the search side can use the existing sta

bq: or is it dependent on query load and performance sla's
Exactly. The critical bit is that every single replica meets your SLA.
By that I mean let's claim that your SLA is 500ms. If you can
serve 10 qps at that SLA with one replica/shard (i.e. leader only)
you can server 50 QPS by adding 4 more
Thanks for the feedback Eric.
I am assuming the number of replicas help in load balancing and reliability.
That being said are there any recommendation for that, or is it dependent on
query load and performance sla's.
Any suggestions on aws setup?
Thanks

For collections with this few nodes, 3 zookeepers are plenty. From
what I've seen people don't go to 5 zookeepers until they have
hundreds and hundreds of nodes.
100M docs can fit on 2 shards, I've actually seen many more. That
said, if the docs are very large and/or the searchers are complex

Hi,
In my current setup I have about 30 million docs which will grow to 100
million by the end of the year. In order to accommodate scaling and query
load, i am planning to have atleast 2 shards and 2/3 replicas to begin
with. With the above solrcloud setup I plan to have 3 zookeepers in the
