Reading this recently published blog post I wonder how was this indexing improvement achieved. I have two main questions:

What kind of storage was used for the stateful cluster? Was it network based storage or local SSD disks?

Were consistency guarantees reduced? If only segments are being replicated to the object store is there a point in time during which an indexing node holds the single copy of a segment or some segments?
