Subject SOLR replication question?
Date Mon, 29 Jul 2013 22:17:41 GMT
I am currently using SOLR 4.4. but not planning to use solrcloud in very near

I have 3 master / 3 slave setup. Each master is linked to its corresponding
slave.. I have disabled auto polling.. 

We do both push (using MQ) and pull indexing using SOLRJ indexing program.

I have enabled soft commit in slave (to view the changes immediately pushed
by queue).

I am thinking of doing the batch indexing in master (optimize and hard
commit) and push indexing in both master / slave. 

I am trying to do more testing with my configuration but thought of getting
to know some answers before diving very deep...

Since the queue pushes the docs in master / slave there is a possibility of
slave having more record compared to master (when master is busy doing batch
indexing).. What would happen if the slave has additional segments compared
to Master. will that be deleted when the replication happens.

If a message is pushed from a queue to both master and slave during
replication, will there be a latency in seeing that document even if we use
softcommit in slave?

We want to make sure that we are not missing any documents from queue (since
its updated via UI and we don't really store that data anywhere except in
