tombstone/types.proto

Tombstone keeps record of deleted objects for a few epochs until they are purged from the NeoFS network.

Field	Type	Label	Description
expiration_epoch	uint64		Last NeoFS epoch number of the tombstone lifetime. It's set by the tombstone creator depending on the current NeoFS network settings. A tombstone object must have the same expiration epoch value in `__SYSTEM__EXPIRATION_EPOCH` (`__NEOFS__EXPIRATION_EPOCH` is deprecated) attribute. Otherwise, the tombstone will be rejected by a storage node.
split_id	bytes		16 byte UUID used to identify the split object hierarchy parts. Must be unique inside a container. All objects participating in the split must have the same `split_id` value.
members	neo.fs.v2.refs.ObjectID	repeated	List of objects to be deleted.
