Subject SorCloud Sharding
Date Wed, 02 May 2018 13:22:24 GMT

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*
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?
