Work Description: anuengineer commented on issue #1588: HDDS-1986. Fix
listkeys API.
URL: https://github.com/apache/hadoop/pull/1588#issuecomment-540666797
Let us get this in, I expect some of these things we will learn the right
choices only when we really benchmark and test. The sad this is that some of
these changes can make our system unstable.
FYI: @elek , I know that you might not be happy with this approach. But it
is hard to judge the impact of these change till we have this code in and start
testing.

> This Jira is to fix listKeys API in HA code path.
> In HA, we have an in-memory cache, where we put the result to in-memory cache
> and return the response, later it will be picked by double buffer thread and
> it will flush to disk. So, now when do listkeys, it should use both in-memory
> cache and rocksdb key table to list keys in a bucket.
