----------------------------------------
Summary: Make SolrCloud Data-center, rack or zone aware
Key: SOLR-6205
URL: https://issues.apache.org/jira/browse/SOLR-6205
Project: Solr
Issue Type: New Feature
Components: SolrCloud
Affects Versions: 4.8.1
Reporter: Arcadius Ahouansou
Use case:
Let's say we have SolrCloud deployed across 2 Datacenters, racks or zones A and
B
There is a need to have a SolrCloud deployment that will make it possible to
have a working system even if one of the Datacenter/rack/zone A or B is lost.
- This has been discussed on the mailing list at
http://lucene.472066.n3.nabble.com/SolrCloud-multiple-data-center-support-td4115097.html
and there are many workarounds that require adding more moving parts to the
system.
- On the above thread, Daniel Collins mentioned
https://issues.apache.org/jira/browse/ZOOKEEPER-107
which could help solve this issue.
- Note that this is a very important feature that is overlooked most of the
time.
- Note that this feature is available in ElasticSearch.
