Autoscaling in 8.2
Hi,
I have one node started with solrcloud. I have created one collection
with the default configsets. When I am creating another node joining the
same cluster i.e. zookeeper chroot, is there any way to create the
collection ? Currently it is just sitting idle, not doing any work.
In the documentation it is not mentioned about this. Only replicas and
shards.
While a new node joins the cluster, is there a way to propagate the
collection creation and later all the shards/replicas being created
accordingly?

Thanks & Regards

You can have replication policies if you don’t want to replicate manually, but automatically:

So you want the new node to host some part of the original collection, right?
use the Collections API ADDREPLICA or MOVEREPLICA commands is the easiest.
Best,
Erick

So my setup is this:
1 node
1 collection (created via collection API)
1 shard
1 replica
This node is connected to zookeeper.
Now let's say I added one more node to the zookeeper, this node is new,
hence there won't be any collection created for me automatically. It is a
barebane node i.e. connected to the same cluster. Is there a way to sync
the data in node 2 which doesn't have a collection as it is joined recently
and also no collection has been created.

You need to create a replica of the collection on the other node:

I really don’t understand the question. If you’ve created a new collection, presumably it’s got a different name, correct? So you need to send some documents to that collection and then query it for it to “do any work”.
I.e.
http://localhost:8983/solr/original_collection/update….
http://localhost:8983/solr/original_collection/query….
.vs.
http://localhost:8983/solr/new_collection/update…..
http://localhost:8983/solr/new_collection/query….
