Hi, I am having 100 million keys in a cluster of 4 using bitcask as the storage system and on riak-0.14.2 version. When I deleted around 30 million key then there was no decrease in the memory usage (which was around 9 GB on each 4 nodes). Sean told me that It may be because of tombstones accumulation, so I waited for the merge process to trigger.
After natural merging (i.e. with default configs), one of the nodes is at 6 gb, the other on 8.5gb and rest on 9 gb. Is it normal to have such an imbalance? Also, while testing I found that If one of the nodes goes down during deletion process, I can still access them when that node comes up..!!! Is this a bug in riak 0.14?? Will migrating to riak 1.0 solve this problem ?? I am afraid that it may rehash the entire data as there is an imbalance in my cluster now. Thanks in Advance Vicky Khanna
