Subject Re: Solr Cloud - How to balance Batch and Queue indexing?
Date Tue, 30 Jul 2013 07:18:49 GMT

Do you want 5 replicas? 1 or 2 is enough.

If you already have 100 million records, you don't need to do batch
indexing. Push it once, Solr has the capability to soft commit every N docs.

Use round robin and send documents to different core. When you search,
search from all the cores.

How you want to setup your servers. Master & Slave OR Fail over. In case of
Master & Slave, Index documents in master and do search from replica cores.
In case of Fail over, your replica will be used once your main server is
