This seems like the crux of the decoupling, so a good comment here will be really helpful. I don't have any good suggestions beyond "orchestrates translog operations" or something generic like that, but a comment would be helpful to explain why this exists, what it is intended to do, how it relates to the Translog class, etc.

Also, can this be package private? And any reason to prefer an abstract class over an interface since no implementations are provided here?

Thanks @andrross, yes the java docs are WIP, will fix them up, I am tightening a bunch of stuffs now that I have tests under control. Since the PR is already 24 files I also intend to break this down. Have changed the abstract class(which I thought I would abstract out few methods) but since I couldn't changing it back to an interface. Feel free to share your high level comments though till I get the PR in a reviewable state

Just to make sure I understand this at a high level, you're pulling the translog-related operations out of Engine and putting them into a TranslogManager (which is an interface with multiple implementations), and the engine holds a reference to a TranslogManager instance. The three implementations of TranslogManager here are:

InternalTranslogManager: this is responsible for the durability of uncommitted writes, as well as replication (i.e. document replication). This is the status quo before seg rep existed.

WriteOnlyTranslogManager: this is responsible for the durability of uncommitted writes, but not replication. Used when segment replication is enabled.

NoOpTranslogManager: does nothing. Used by NoOpEngine.

Is all this right? This seems reasonable to me. It seems like a good structural refactoring that allows for cleaner injection of different translog-related logic. It seems to line up with @nknize's suggestion from another PR as well.

You got that right @andrross. Thanks

* Support unknown node role Currently OpenSearch only supports several built-in nodes like data node role. If specify unknown node role, OpenSearch node will fail to start. This limit how to extend OpenSearch to support some extension function. For example, user may prefer to run ML tasks on some dedicated node which doesn't serve as any built-in node roles. So the ML tasks won't impact OpenSearch core function. This PR removed the limitation and user can specify any node role and OpenSearch will start node correctly with that unknown role. This opens the door for plugin developer to run specific tasks on dedicated nodes.
