Subject Re: Avoid re indexing
Date Sat, 01 Aug 2015 23:25:02 GMT
If my current shard is holding 3 million documents will the new subshard after splitting also
be able to hold 3 million documents?
If that is the case After shard splitting the sub shards should hold 6 million documents if
a shard is split in to two. Am I right?
