hi
when we have more and more machines, we have replications of indexes and
also many shards which hold a part of the whole indexes.
we have to do many things: fail-over, load balance, log collecting,
monitoring each machine's status, ....
Solr only did a small number of these now. some one mentioned Katta and
SolrCloud.
Katta based on lucene and can't utilize solr's effort.
What about SolrCloud? Or any other related things?
