Hi Asad,

Please use the query method.  For reading directly from the underlying data
storage, we should always read from the Leader (it could be tricky to
implement failover).  Even reading from the Leader, it could get stale data
in some cases.

When using the query method, Ratis can be configured to support
linearizable-read, read-from-followers and read-after-write consistency.
Linearizable-read guarantees no stale data.  When linearizable-read is
enabled, clients can also read from followers with the same guarantee.
When read-after-write consistency is enabled, a client will always read the
results after the writes from itself (otherwise, a read can return before a
write, even if the write async call is submitted before the read async
call).
