摘要： A distributed storage system may store data object instances in persistent storage and may store keymap information for those data object instances in a distributed hash table on multiple computing nodes. Each data object instance may include a composite key containing a user key. The keymap information for each data object instance may map the user key to a locator and the locator to the data object instance. A request to store or retrieve keymap information for a data object instance may be routed to a particular computing node based on a consistent hashing scheme in which a hash function is applied to a portion of the composite key of the data object instance. Thus, related entries may be clustered on the same computing nodes. The portion of the key to which the hash function is applied may include a pre-determined number of bits or be identified using a delimiter.

摘要： Methods and apparatus for lifecycle support for storage objects are disclosed. A storage medium stores program instructions that when executed on a processor implement a storage lifecycle manager of a multi-tenant storage service. The lifecycle manager determines a lifecycle policy to be implemented for a storage object. The policy indicates lifecycle transitions of the object, including a transition from a first service level to a second service level. The first service level and the second service level may each specify a maximum number of versions of the storage object. The lifecycle manager initiates modification operations corresponding to the storage object's data in accordance with the lifecycle policy, and verifies that the modification operations succeeded. The lifecycle manager provides, in response to a query, an indication of a current service level of the storage object.

摘要： Systems and methods for providing object versioning in a storage system may support the logical deletion of stored objects. In response to a delete operation specifying both a user key and a version identifier, the storage system may permanently delete the specified version of an object having the specified key. In response to a delete operation specifying a user key, but not a version identifier, the storage system may create a delete marker object that does not contain object data, and may generate a new version identifier for the delete marker. The delete marker may be stored as the latest object version of the user key, and may be addressable in the storage system using a composite key comprising the user key and the new version identifier. Subsequent attempts to retrieve the user key without specifying a version identifier may return an error, although the object was not actually deleted.

摘要： Embodiments of system and method for performing object-modifying commands in an unstructured storage service are described. Embodiments may include utilizing one or more nodes to implement an unstructured storage service including a service interface configured to service data storage requests and data retrieval requests from remote clients. The unstructured storage service is configured to isolate access to each of multiple storage domains of the service to different clients. Embodiments may also include receiving from a given remote client, a request to store a data object to a given storage domain of the service. The request further specifying a command to modify source data for the object prior to storing the object. Embodiments may also include using the unstructured storage service to perform the command without exporting the source data from the unstructured storage service to the given remote client prior to completion of the command.

摘要： Methods and apparatus for backoff-based scheduling of storage object deletions are disclosed. A storage medium stores program instructions that when executed on a processor, obtain an indication of a collection of storage objects of a network-accessible multi-tenant storage service to be deleted in accordance with specified deletion criteria. A deletion of a storage object comprises a metadata deletion operation and one or more other operations. The instructions initiate, corresponding to at least some objects of the collection, respective metadata deletion operations at a metadata node of the storage service. If a metric associated with the metadata node meets a threshold criterion, the instructions delay, by a particular amount of time, an initiation of an operation corresponding to a deletion of another storage object.
