Siddharth Wagle commented on HDDS-2116:
---------------------------------------
Hi [~timmylicheng], we can certainly punt it if there is no need for it. But,
the intention was to encapsulate the instantiation of pipeline allocation
strategies in the AllocationManager based on different configurations. The
reason it might not be needed is if we are already capturing this behavior
somewhere else. It is ok to leave this open, I suspect we would need it.
> Create SCMAllocationManager as background thread for pipeline creation

> SCMAllocationManager can be leveraged to get a candidate set of datanodes
> based on placement policies. And it should make the pipeline creation process
> to be async and multi-thread. This should be done when we encounter with
> performance bottleneck in terms of pipeline creation.
