Question regarding Upgrading to SolrCloud

[Gopesh Sharma <Go...@gensler.com>]

Hello Guys,

As of now we are running Solr 3.4 with Master Slave Configuration. We are planning to upgrade it to the lastest version (6.6 or 7). Questions I have before upgrading


  1.  Since we do not have a lot of data, is it required to move to SolrCloud or continue using it Master Slave
  2.  Is the support for Master Slave will be there in the future release or do you plan to remove it.
  3.  Can we configure master-slave replication in Solr Cloud, if yes then do we need zookeeper as well.

Thanks,
Gopesh Sharma

The 7.0 Ref Guide was released Monday.

An overview of the new replica types is available online here:
https://lucene.apache.org/solr/guide/7_0/shards-and-indexing-data-in-solrcloud.html#types-of-replicas.
The replica type is specified when you either create the collection or
add a replica.

Gopesh:

There is brand new functionality in Solr 7, see: SOLR-10233, the
"PULL" replica type which is a hybrid SolrCloud replica that uses
master/slave type replication. You should find this in the reference
guide, the 7.0 ref guide should be published soon. Meanwhile, that
JIRA will let you know. Also see .../solr/CHANGES.txt. As Emir says,
though, it would require ZooKeeper.

Really, though, once you move to SolrCloud (if you do) I'd stick with
the standard NRT replica type unless I had reason to use one of the
other two, (TLOG and PULL) as they're for pretty special situations.

All that said, if you're happy with master/slave there's no compelling
reason to go to SolrCloud, especially for smaller installations.

Best,
Erick
