摘要： A distributed, web-services based storage system. A system may include a web services interface configured to receive, according to a web services protocol, a given client request for access to a given data object, the request including a key value corresponding to the object. The system may also include storage nodes configured to store replicas of the objects, where each replica is accessible via a respective unique locator value, and a keymap instance configured to store a respective keymap entry for each object. For the given object, the respective keymap entry includes the key value and each locator value corresponding to replicas of the object. A coordinator may receive the given client request from the web services interface, responsively access the keymap instance to identify locator values corresponding to the key value and, for a particular locator value, retrieve a corresponding replica from a corresponding storage node.

摘要： Dynamic object replication in distributed storage systems. A system may implement a web services interface, storage nodes, storage node selection logic and a coordinator. The web services interface may be configured to receive, according to a web services protocol, client requests to store data objects including a given client request to store a given one of the data objects. The storage nodes may be configured to store replicas of the data objects. The storage node selection logic may be configured to dynamically determine a write plan for storing replicas of the given data object to corresponding storage nodes, where the write plan is dynamically determined according to current state information of the storage nodes. The coordinator may be configured to receive the client requests from the web services interface, and for the given client request, to store the replicas of the given data object to the corresponding storage nodes according to the write plan.

摘要： A distributed storage system including support for distinct storage classes. A system may implement a web services interface, a number of storage nodes and a coordinator. The web services interface may receive, according to a web services protocol, client requests to store data objects. A request for a given object may include an indication of a particular storage class to be associated with the given object, and where each storage class respectively specifies one or more service level agreement (SLA) characteristics. The storage nodes may store replicas of the data objects. The coordinator may receive the client requests to store the data objects from the web services interface, where in response to the given client request, the coordinator may store one or more replicas of the given data object among the storage nodes according to the SLA characteristics specified by the particular storage class.

摘要： Dynamic application instance discovery and state management within a distributed system. A distributed system may implement application instances configured to perform one or more application functions within the distributed system, and discovery and failure detection daemon (DFDD) instances, each configured to store an indication of a respective operational state of each member of a respective group of the number of application instances. Each of the DFDD instances may repeatedly execute a gossip-based synchronization protocol with another one of the DFDD instances, where execution of the protocol between DFDD instances includes reconciling differences among membership of the respective groups of application instances. A new application instance may be configured to notify a particular DFDD instance of its availability to perform an application function. The particular DFDD instance may be configured to propagate the new instance's availability to other DFDD instances via execution of the synchronization protocol, without intervention on the part of the new application instance.
