Step S212- steps S216 is accomplished that the deletion to incidence relation, and the main thought being related to is that deletion contains the
Association reference information in the object of two fields, and delete in addition to itself, it is not associated and draws by other any object
The related information of object.If asking to be stored with the first field in the object deleted, and there are other in addition to itself
Object refer to related information by the second field, then the related information of the object can not be deleted.When by the related information phase
After related information in all objects closed is all deleted, then delete the object.
Step S217, reception object removal request, the object removal request carry the 3rd object identity；
It is whether in step S218, judgement metadata corresponding with the 3rd object identity with entitled first field
Or second field field；
Step S219, if it is not, deleting corresponding with the 3rd object identity the 3rd object.
Step S217- steps S219 is accomplished that the deletion to object in object storage system, is deleted receiving object
After request, judge to be whether the word with entitled first field or the second field in metadata corresponding with the 3rd object identity
Section, failure is deleted if so, then returning, and points out to store relevant in the reason for user or operation system delete failure, such as object
Information or association reference information, if it is not, then directly deleting object from object storage system.
It should be noted that being walked for what step S204- steps S209 was realized to the enumerating of related information, step S210-
What rapid S211 was realized realize to the addition of incidence relation, step S212- steps S216 to incidence relation deletion and step
Can be independently real between these schemes that object is deleted from object storage system that S217- steps S219 is realized, each scheme
Apply, without with absolute adduction relationship and execution sequence.
