Abstract: A system that implements a data storage service may store data in multiple replicated partitions on respective storage nodes. The selection of the storage nodes (or storage devices thereof) on which to store the partition replicas may be performed by administrative components that are responsible for partition management and resource allocation for respective groups of storage nodes (e.g., based on a global view of resource capacity or usage), or the selection of particular storage devices of a storage node may be determined by the storage node itself (e.g., based on a local view of resource capacity or usage). Placement policies applied at the administrative layer or storage layer may be based on the percentage or amount of provisioned, reserved, or available storage or IOPS capacity on each storage device, and particular placements (or subsequent operations to move partition replicas) may result in an overall resource utilization that is well balanced.

Abstract: Asynchronous namespace maintenance in a distributed replicated data storage system is disclosed. An access device/program serving as a front end to the distributed replicated data storage system updates a batch of updated meta data about stored data items when data items are stored in the distributed replicated data storage system. When the elapsed time since the last batch of data item meta data was stored exceeds a first threshold value or the current batch size exceeds a second threshold value, the access device/program stores the current batch of updated meta data as an object in the distributed replicated data storage system, receiving a batch object identifier for the stored batch of updated meta data, and distributes the batch object identifier to other access devices and/or access programs which retrieve the batch of updated meta data and update their namespaces.

Abstract: Disclosed are various embodiments for reducing locking in a distributed data store that includes a primary data store and one or more secondary data stores. An update to a data item that is to be applied to the distributed data store is obtained in one or more computing devices. The update is applied to a cached version of the data item when a lock is held. The update is replicated to the one or more data stores after the lock is released. It is determined that the update is durably persisted in the distributed data store after obtaining a replication confirmation from each of at least a predetermined number of the secondary data stores.

Abstract: One or more techniques and/or systems are disclosed for efficiently storing metadata of partitioned data (e.g., directed to a specific individual/user). A first subset of data is identified from the set of partitioned data. The first subset of data comprises data that has a high frequency of access, and may be identified, at least in part, by frequency of access metadata that is associated with the data in the set. Metadata, such as discovery information, permissions, version info, etc., that is associated with the data in the first subset can be stored in low latency (e.g., fast) storage, proving more efficient access. Metadata associated with data from the set of partitioned data that is not in the first subset (e.g., that is not accessed frequently) can be stored in higher latency (e.g., slower, less expensive) storage.

Abstract: Both live and offline transcoding of media is managed for storage in a cache. Requests for media are made by a client on a network and media taken from the cache and transcoded for delivery to the client. Media is also transcoded and stored in memory during idle request in anticipation of future requests during idle transcoder time between client requests. A prioritizer manages at least offline transcoding requests. A high priority queue operates at a higher priority than the low priority queue. The high priority queue receives live transcoding requests from a client on the network. A low priority queue receives offline transcoding requests. A media transcoder primarily transcodes media in accordance with requests from the high priority queue for delivery to a client on the network and then secondarily transcodes media in accordance with requests from the low priority queue when the high priority queue is empty.

Abstract: Techniques are provided to allow users to define a global service that is offered across multiple replicated databases. Database clients connect to and use a global service just as they do with regular services on a single database today. Upon receiving a connection request, a collection of components, referred to collectively as the Global Data Service framework (GDS framework), automatically chooses the best database server instances to which to connect a client. Once those connections have been established, the clients determine which database server instance, of those database server instances to which they are connected, to send requests to based, at least in part, on advisory messages sent to the clients by the GDS framework.

Abstract: An on-disk structure of a file system has the capability to efficiently manage and organize data containers, such as snapshots, stored on a storage system. A multi-bit, monotonically increasing, snapshot identifier (“snapid”) is provided that represents a snapshot and that increases every time a snapshot is generated for a volume of the storage system. The snapid facilitates organization of snapshot metadata within, e.g., a data structure used to organize metadata associated with snapshot data. In the illustrative embodiment, the data structure is a balanced tree structure configured to index the copy-out snapshot data blocks. The snapid is also used to determine which blocks belong to which snapshots. To that end, every block that is used in a snapshot has an associated “valid-to” snapid denoting the newest snapshot for which the block is valid. The oldest snapshot for which the block is valid is one greater than the valid-to field of the next older block at the same file block number.

A substantial speedup is obtained by copying regions of the file in parallel.

Abstract: A system, a method and computer-readable media for managing content received over a network by a client device. A network transmission communicating an item of content is detected by a client device, and a determination is made whether the client device is in a mode of operation that allows the storing of uninvited media content. For example, the client device may be a mobile communication device monitoring the media being transmitted over a broadcast channel. When an item of content is observed traversing the broadcast channel, a set of user-defined preferences is accessed to determine whether to permit receiving the item. If permitted, the item of content is stored in a data store on the client device for subsequent presentation to the user.

A DROP operation shifts responsibility for rows of data from one partition to another partition and then drops the rows from the one partition.

Abstract: The technique introduced here involves using a block address and a corresponding generation number as a “fingerprint” to uniquely identify a sequence of data within a given storage domain. Each block address has an associated generation number which indicates the number of times that data at that block address has been modified. This technique can be employed, for example, to determine whether a given storage server already has the data, and to avoid sending the data to that storage server over a network if it already has the data. It can also be employed to maintain cache coherency among multiple storage nodes.
