------------------------------------
Hi [~xyao]
Thanks for helping to review this, please see my comments below
bq. Should we change the KeyUtils.getDB here to use the abstracted interface
instead of the hardcoded LevelDBStore? ... Similar question to SCM components
I was trying not to fix all LevelDBStore in this patch, that will make this
patch a very big one. But I actually have done some more work so I can add them
in one patch if you like. I was thinking that is not easy for review so I split
the work to 3 steps: 1) create general abstraction, the interface 2) Replace
existing levelDB references 3) implement rocksDB; I can combine 1 & 2 in this
JIRA, if you prefer.
I will fix rest of issues in the comments.
Thank you!
