Xiaoyu Yao commented on HDDS-271:
---------------------------------

[~bharatviswa], KeyValueBlockIterator#hasNext can be expensive without 
Bloomfilter for the key not found case. This will be addressed when [~anu] 
enable bloomfilter for the rocksdb metadata store. 

 

Based on that, I'm +1 patch v4.
