Hi, I have few questions on sharding in a SolrCloud setup:
1. How to know the optimal number of shards required for a SolrCloud setup? What are the factors to consider to decide on the value for *numShards* parameter? 2. In case if over sharding has been done i.e. if numShards has been set to a very high value, is there a mechanism to merge multiple shards in a SolrCloud setup? 3. In case if no such merge mechanism is available, is reindexing the only option to set numShards to a new lower value? Thnx.
