A database system may include a database service and a separate distributed storage service. The database service (or a database engine head node thereof) may be responsible for query parsing, optimization, and execution, transactionality, and consistency, while the storage service may be responsible for generating data pages from redo log records and for durability of those data pages. For example, in response to a write request directed to a particular data page, the database engine head node may generate a redo log record and send it, but not the data page, to a storage service node. The storage service node may store the redo log record and return a write acknowledgement to the database service prior to applying the redo log record. The server node may apply the redo log record and other redo log records to a previously stored version of the data page to create a current version.

Database system with database engine and separate distributed storage service

A computer system may receive a layout of a data center, the layout of the data center identifying physical locations of a plurality of server racks, electrical distribution feeds, and uninterruptible power supplies. The computer system may receive a fault domain configuration for the datacenter, the fault domain configuration identifying virtual locations of a plurality of logical fault domains for distributing one or more instances so that the instances are stored on independent physical hardware devices within a single availability fault domain. The computer system may determine the configuration for the data center by assigning the plurality of fault domains to a plurality of electrical zones, wherein each electrical zone provides a redundant electrical power supply across the plurality of logical fault domains in an event of a failure of one or more electrical distribution feeds. The computer system may display the configuration for the data center on a display.

Techniques for generating a configuration for electrically isolating fault domains in a data center

Techniques are disclosed for efficient utilization worker threads in a workflow-as-a-service (WFaaS) environment. A client device may request a workflow for execution by the client device. The client device may receive the requested workflow and initialize a set of worker threads to execute the workflow and a set of heartbeater threads to monitor the set of worker threads. Upon receiving an indication of a processing delay, the client device may capture the state of the workflow, suspend execution of the workflow, and store the workflow in a temporary queue. While the processing delay persists, the client device may use the set of worker threads to execute other tasks. When the processing delay terminates, the client device may resume execution of the workflow.

Efficient worker utilization

Methods and systems for dynamically incorporating advertising content into multimedia environments, such as games, are provided. Example embodiments include a dynamic inserter, which selects content, based upon a set of criteria, to deliver to a receiving client system, such as a game client. The game client typically dynamically determines locations with the game where advertisements may be inserted. Associated with these locations are ad tags that specify criteria for the ads. For example, the criteria may include ad type, ad genre, and scheduling information. The game client then sends indications of these ad tags to the dynamic inserter to be used to select appropriate ads. The dynamic inserter selects ads based upon the criteria and sends them to the game client, which selects them for ad tags with conforming criteria. The game client then renders the selected ad in the appropriate location. In one embodiment, the dynamic inserter comprises a game client, game server, ad server, a communications channel, and, optionally, an ad client.

Method and system for dynamically incorporating advertising content into multimedia environments

Nodes of a database service may receive a read request to perform a read of a record stored by the database service and a transaction request to perform a transaction to the record. First and second indications of time may be associated with the read and transaction, respectively. A potential read anomaly (e.g., fuzzy read, read skew, etc.) may be detected based, at least in part, on a determination that the first indication of time is within a threshold value of the second indication of time. In response to detecting the potential read anomaly, the read may be performed after the transaction specified by the transaction request, regardless of whether the first indication of time is indicative of an earlier point in time than the second indication of time.

Transaction ordering

A log-structured distributed storage system may implement individual write quorums. Log records may be sent to different storage nodes of a quorum set storing data for a storage client sufficient to satisfy a write quorum requirement. For each log record, acknowledgments from storage nodes are received, and a determination is made whether the write quorum requirement is satisfied for the log record. Different log records may be maintained at different storage nodes, and still satisfy the write quorum requirement such that in some embodiments no one storage node may maintain all of the log records sent to storage nodes in the quorum set.

Individual write quorums for a log-structured distributed storage system

A resource delivery network and method for distributing content in the network is disclosed herein. The network comprises a plurality of servers arranged in tiers and partitioned. Each server includes a resource store with a set of resources for distribution to a successive tier. Updates to each successive tier are provided by a pull-forward client on servers in the tier. This forward propagation mechanism maximizes resource availability at edge servers in the network. Resources transmitted to the edge tier servers may be transformed, combined, and rendered without taxing lower tier servers. Transformation and pre-rendering of data can be performed by low priority CPU tasks at each layer of the system.
