sivabalan narayanan updated HUDI-2422:
--------------------------------------
Description:
Add rollback plan and rollback requested instant
follow ups:
1. Upgrade/downgrade infra:
Need an upgrade step. If there are any inflight rollback, we need to create
rollback.requested with rollback plan.
downgrade:
If there is just rollback.requested, delete it and create an rollback.inflight
for the same instant. But this meta file will not have any info on which
instant to be rolledback (in 090). So, not sure if we can do anything much
here.
2. Fix all cli tools.
3. We have a class called ListingBasedRollbackRequest. With this new approach,
we anyways need HoodieRollbackRequest to be serialized as part of RollbackPlan.
Hence this class ListingBasedRollbackRequest as such does not help much. We can
get rid of this. but it might involve touching few classes. Hence adding it
here as a follow up.
