bq: If you switch to SolrCloud, will you still keep numShards parameter to 1
yes. Although if you want to add more replicas you might want to specify that.
For 10M documents, I wouldn't be very fancy. Indexing them shouldn't take
very long, and I think your time would be better spent on other things than
trying to get fancy with splitshard and the like. Just create a
SolrCloud cluster
with as many replicas as you want and index from scratch unless it's
prohibitively expensive.
I can index 200M docs on my local Mac Pro in a couple of hours. Is it really
worth trying to do something you'll probably never do again (i.e. SPLITSHARD)?
If you really don't want to re-index _and_ you have only one shard in the
master/slave setup, here's what I'd do to migrate
1> create a new SolrCloud cluster with exactly one node (i.e. the "leader").
2> shut it down
3> copy the index from your master/slave to the new node, completely
replacing the data directory
4> bring the node back up and check it.
5> use the collecitons API ADDREPLICA command to bring up as many
replicas as you want, they'll pull down the index and from that point on
you should be good.
5a> In this case, it'll actually do a complete replication from the leader to
the followers, but thereafter incremental updates will be sent to all
the nodes in the cluster rather than the older style master/slave
occasional replication.
Best,
