Abstract: A disclosed computer-implemented method may include partitioning, based on a social graph representative of social connections among a plurality of users of a social networking system, the plurality of users into a plurality of user buckets. Each user bucket may include at least one user of the social networking system. The method may further include selecting a set of user buckets from the plurality of user buckets, assigning the set of user buckets to a data center included in a networking infrastructure, and routing data sent from a user device associated with a user included in the set of user buckets to the data center. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A disclosed computer-implemented method may include receiving, via a monitoring infrastructure that monitors an operational state of a networking infrastructure, data representative of the operational state of the networking infrastructure during a period of time. The networking infrastructure may include (1) a plurality of data centers, and (2) at least one point-of-presence (POP) edge node. The method may also include (1) accessing data representative of a set of predefined policies associated with the networking infrastructure, and (2) based on the data representative of the operational state (a) determining a set of edge load factors associated with the edge node, and (b) generating, via a linear solver and further based the set of edge load factors associated with the edge node and the set of predefined policies associated with the networking infrastructure, a routing table for the POP edge node. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: In one embodiment, a method includes identifying and recursively populating a geographic tile with entities. Recursively populating a geographic tile with entities includes: sending a request to a third-party server for entities located near a representative point of the geographic tile; calculating a maximum distance from the representative point among the entities received; and determining whether a bounding perimeter based on the maximum distance encompasses the geographic tile. If the bounding perimeter encompasses the geographic tile, the retrieved entities located within the geographic tile are stored in association with an identifier for the geographic tile. If the bounding perimeter does not encompass the geographic tile, the geographic tile is divided and the subdivision tiles are recursively populated.

Abstract: The disclosure is directed to a data publishing service that provides a low-latency read access to data. Some applications store data in a format that is not suitable or efficient for retrieving the data in real-time or near real-time. The data publishing service converts the data into a format, e.g., key-value pairs, that provides a low-latency read access to the data. A low-latency read access is a feature that enables retrieval of data in real-time, near real-time, or within a specified read latency. The data publishing service also provides an application programming interface (API), which can be used by a client for accessing the data. The data publishing service can be used to provide low-latency read access to data stored in data sources of various storage formats, e.g., data stored in relational database, log files, or as objects in object-oriented databases.
