  • Publication number: 20180349409
    Abstract: A file system manager implemented at a provider network identifies a storage device of a first group of storage devices of a provider network as an initial location of a file system object. Based on an access metric associated with the object, the file system manager initiates a transfer of contents of the object to a second storage device of a different storage device group, without receiving a client request specifying the transfer. In response to an access request received via a file system programmatic interface, contents of the object are provided from the second storage device. Based on a second access metric, the object is transferred back to the first group of storage devices.

  • Publication number: 20180329936
    Abstract: A materialization configuration request is received via a programmatic interface from a client of a journal-based multi-data-store database. The request indicates a partitioning rule to be used to select, for respective writes indicated in committed transaction entries of a journal, the materialization node at which the writes are to be stored. A control plane component of the database verifies that a set of materialization nodes corresponding to the partitioning rule has been established, and initiates the propagation of writes from the journal to the materialization nodes by respective write appliers.

  • Publication number: 20180322017
    Abstract: A system that implements a data storage service may store data for database tables in multiple replicated partitions on respective storage nodes. In response to a request to restore a given table that was backed up in a remote storage system (e.g., key-value durable storage system), the service may create a new table, and may import a copy of each of the partitions of the given table from the remote storage system into the new table. The request to restore the table may specify a modified value for a configuration parameter for the table or for one of its partitions. The service may apply the new configuration parameter value to the table or its partitions during the restore operation. The new configuration parameter value may indicate an increase or decrease in storage capacity or throughput capacity, and its application may automatically trigger a partition split or move operation.

  • Publication number: 20180324033
    Abstract: A system that implements a data storage service may store data on behalf of storage service clients. The system may maintain data in multiple replicas of various partitions that are stored on respective computing nodes in the system. The system may employ a single master failover protocol, usable when a replica attempts to become the master replica for a replica group of which it is a member. Attempting to become the master replica may include acquiring a lock associated with the replica group, and gathering state information from the other replicas in the group. The state information may indicate whether another replica supports the attempt (in which case it is included in a failover quorum) or stores more recent data or metadata than the replica attempting to become the master (in which case synchronization may be required). If the failover quorum includes enough replicas, the replica may become the master.

    Abstract: A computer system that provides clients access to pooled resources in order to provide computing or data storage services may receive service requests (which explicitly or implicitly include requests for pooled resources), may service at least some of those requests, and may determine pricing for the serviced requests. The pricing for each request may be dependent on whether it was serviced using a portion of a resource pool that was reserved for the use of the client on whose behalf it was received or using burst capacity (e.g., unreserved or otherwise idle capacity within the resource pool). Pricing for the use of reserved capacity may be fixed, regardless of the amount of reserved capacity used. Pricing for burst capacity may depend on actual use, and may be demand-based (e.g., using a spot-market-based dynamic pricing model). Clients with reserved capacity may optionally request access to burst capacity.

  • Publication number: 20180225464
    Abstract: When a client requests a data import job, a remote storage service provider provisions a shippable storage device that will be used to transfer client data from the client to the service provider for import. The service provider generates security information for the data import job, provisions the shippable storage device with the security information, and sends the shippable storage device to the client. The service provider also sends client-keys to the client, separate from the shippable storage device (e.g., via a network). The client receives the device, encrypts the client data and keys, transfers the encrypted data and keys onto the device, and ships it back to the service provider. The remote storage service provider authenticates the storage device, decrypts client-generated keys using the client-keys stored at the storage service provider, decrypts the data using the decrypted client-side generated keys, and imports the decrypted data.

  • Publication number: 20180212898
    Abstract: A resource stack managed by a resource stack provider is created based on a resource stack template that integrates a custom resource from a second provider into the resource stack using a notification system with the second provider. For example, a customer may create a template that defines a resource stack that comprises resources available from the resource stack provider and one or more custom resources provided by a second provider. When a resource stack is created, resources available from the resource stack provider may be provisioned. Custom resources may be initialized by notifying the provider of the custom resource of the requested integration of the custom resource with the resource stack and requested configuration details. The custom resource provider may respond with an indication of successful integration when the custom resource has been successfully initialized. After initializing the resources, the resource stack may be enabled for use.

    Abstract: A data center includes computing devices, an air handling system, a heat engine, and a generator. Air moved by the air handling system flows across heat-producing components in the computing devices in the data center. Heat from air that has flowed over the heat-producing components heats a hot section of the heat engine. The heat engine generates mechanical work based on a temperature differential between a hot section of the heat engine and a cold section of the heat engine. The generator generates electricity from the mechanical work generated by the heat engine.

    Abstract: A distributed database management system may comprise a plurality of computing nodes. A request to update an item maintained by the system may be acknowledged as durable and committed once an entry corresponding to the request has been written to a log file and quorum among the computing nodes has been achieved. Improved consistency may be achieved by maintaining snapshots of committed item states within queryable in-memory snapshot data structures. Range queries may be performed by merging a secondary index with the snapshots and applying filters. Projections may be completed by retrieving additional data from an item collection maintain on one or more storage devices.

  • Publication number: 20180198863
    Abstract: A network-based data store may implement retention-based management techniques for data stored at the network-based data store. When data is received for storage at the network-based data store, a retention time for the data may be determined. Storage locations at persistent storage devices of the network-based data store may be selected according to the retention time. The data may then be placed at the storage locations. When a request to delete data is received, retention times of co-located data may be evaluated to determine whether the deletion may be delayed. Delayed deletions may allow the data to be subsequently deleted with at least some of the co-located data. Repair operations to maintain the data according to a durability policy may be modified according to retention time for a data suffering a loss of redundancy.

  • Publication number: 20180196827
    Abstract: Methods, apparatus, and computer-accessible storage media for controlling export of snapshots to external networks in service provider environments. Methods are described that may be used to prevent customers of a service provider from downloading snapshots of volumes, such as boot images created by the service provider or provided by third parties, to which the customer does not have the appropriate rights. A request may be received from a user to access one or more snapshots, for example a request to export the snapshot or a request for a listing of snapshots. For each snapshot, the service provider may determine if the user has rights to the snapshot, for example by checking a manifest for the snapshot to see if entries in the snapshot manifest belong to an account other than the customer's. If the user has rights to the snapshot, the request is granted; otherwise, the request is not granted.

  • Publication number: 20180189336
    Abstract: A distributed storage system may store data object instances in persistent storage and may cache keymap information for those data object instances. The system may cache a latest symbolic key entry for some user keys of the data object instances. When a request is made for the latest version of stored data object instances having a specified user key, the latest version may be determined dependent on whether a latest symbolic key entry exists for the specified user key, and keymap information for the latest version may be returned. When storing keymap information, a flag may be set to indicate that a corresponding latest symbolic key entry should be updated. The system may delete a latest symbolic key entry for a particular user key from the cache in response to determining that no other requests involving the keymap information for data object instances having the particular user key are pending.

    Abstract: For a given cross-data-store transaction request at a storage service, a coordinator transmits respective voting transition requests to a plurality of log-based transaction managers (LTMs) configured for the respective data stores to which writes are directed in the transaction. The LTMs transmit responses to the coordinator based on data-store-specific conflict detection performed using contents of the voting transition requests and respective data-store-specific state transition logs. The coordinator determines a termination status of the cross-data-store transaction based on the LTMs' responses, and provides an indication of the termination status to the LTMs.
