Review Comment:
@rdblue I think preplan on single snapshot was seen to have value of
breaking up the work into multiple plan tasks as clients can parallelize the
work of obtaining the file scan tasks.
I would assume an incremental scan is the above process but now doing this
distributing of work on multiple snapshots so I would assume this would also be
valuable.
> This has a few implications, like whether we should call plan first
I dont think in general in this protocol so far( for both snapshot scan or
incremetal scan) we gave clear instructions of whether clients should be
calling `plan` or `preplan` first. I would assume clients can choose to call
`plan` first and if there is an issue they would receive the `421` or `422`
error instructing clients to call `preplan` before `plan`.
