Duo Zhang commented on HBASE-21246:
-----------------------------------
Why we have a getSize in WALIdentity?
And do we want to introduce some structures in the WALIdentity? If not, why not
just use a String? You introduced a method which creates a WALIdentity from a
String, then why not just use String as the identity?
> Introduce WALIdentity interface

> We are introducing WALIdentity interface so that the WAL representation can
> be decoupled from distributed filesystem.
> The interface provides getName method whose return value can represent
> filename in distributed filesystem environment or, the name of the stream
> when the WAL is backed by log stream.
