摘要： Techniques are described herein for performing database operations against location and access transparent metadata units called fat pointers organized into globally distributed data structures. The fat pointers are created by extracting values corresponding to a particular key and paring each value with a reference to the local location and server that has the native format record containing the value. The fat pointers may be transferred to any server in the cluster, even if the server is different from the server that has the native format record. In general, most operations are performed against fat pointers rather than the native format records. This allows the cluster to perform work against arbitrary types of data efficiently and in a constant amount of time despite the variable sizes and structures of records.

摘要： Mechanisms are provided for performing a matrix operation. A processor of a data processing system is configured to perform cluster-based matrix reordering of an input matrix. An input matrix, which comprises nodes associated with elements of the matrix, is received. The nodes are clustered into clusters based on numbers of connections with other nodes within and between the clusters, and the clusters are ordered by minimizing a total length of cross cluster connections between nodes of the clusters, to thereby generate a reordered matrix. A lookup table is generated identifying new locations of nodes of the input matrix, in the reordered matrix. A matrix operation is then performed based on the reordered matrix and the lookup table.

摘要： In one embodiment, one or more computing devices receive, from a client device of a first user, a query from the first user. The computer devices search a social graph to identify one or more nodes of the social graph that are relevant to the query. The computer devices obtain a static rank for each identified node. The static rank is based at least in part on a number of edges of a particular edge type that are connected to the node in the graph or attributes of edges connected to the node in the graph. The computer devices send to the client device of the first user for display, a search-results page responsive to the received query. The search-results page includes reference to one or more nodes having a static rank greater than a threshold rank.

摘要： Technology is disclosed for a multi-tiered querying system to target queries to systems storing data relevant to the query. A multi-tiered targeted query system comprises at least three tiers: a web tier, an aggregator tier, and a shards tier. Servers at the web tier can be configured to service user data requests and pass them to servers at the aggregator tier. Servers at the aggregator tier can be configured to determine which selected shard servers have the requested information; formulate queries for the selected shard servers; send the queries to the selected shard servers; and aggregate results from the selected shard servers. Servers at the shard tier can be configured to store data, receive queries on that data, and return results for received queries.
