------------------------------------
Hi [~nandakumar131]
Thanks for reviewing this. I agree with your all 3 comments, I'll address #1
and #2 in next patch, about #3, I listed as a TODO item and I plan to do that
in another patch. See {{DistributedStorageHandler#listBuckets}}
{noformat}
// Get bucket list from KSM. Note it is possible the client
// only provides the volume name. KSM will return all buckets
// belong to this user in this volume in a huge list.
// TODO add a safe check in case bucket list overflows, e.g >100.
{noformat}
but yeah, it probably worth to add a check for the utility method
{{LevelDBStore#getRangeKVs}} as well, but it would be tricky how to define the
limit... anyway, I will open another JIRA to track this.
Thank you.
