you query? Is it distribute the data equally? What is the basis? Which part

Re: How sorlcloud distribute data among shards of the same cluster?
Posted by Boon Low <bo...@brightsolid.com>.
Thanks. My colleague also pointed a previous thread and the solution out: add a new update.chain for data import/update handlers to bypass the distributed update processor.
A simpler use case example for SolrCloud newbies could be on distributed search, to experience the features of the cloud-based version, how it compares with the existing distributed search. This involves firing up a single node SolrCloud, quickly re-creating multiple logical cores with existing tools and testing them within a search collection. The default distributed update processor may be confusing in this case. At least how it can be opted out should be explained on the wiki.
Impressed with the distributed search and real-time update!

You can remove the distrib update processor and just distrib the data yourself.
Eventually the hash implementation will also be pluggable I think.

Re: How sorlcloud distribute data among shards of the same cluster?
Posted by Boon Low <bo...@brightsolid.com>.
Hi,
Is there any mechanism in SolrCloud for controlling how the data is distributed among the shards? For example, I'd like to create logical (standalone) shards ('A', 'B', 'C') to make up a collection ('A-C"), and be able query both a particular shard (e.g. 'A') or the collection entirely. At the moment, my test suggests 'A' data is distributed to evenly to all shards in SolrCloud.
Regards,
Boon

Try looking at DistributedUpdateProcessor, there's
a "hash(cmd)" method in there.

Re: How sorlcloud distribute data among shards of the same cluster?
Posted by emma1023 <sm...@gmail.com>.
Thanks for your reply. In sorl 3.x, we need to manually hash the doc Id to
the server.How does solrcloud do this instead? I am working on a project
using solrcloud.But we need to monitor how the solrcloud distribute the
data. I cannot find which part of the code it is from source code.Is it
from the cloud part? Thanks.
