Load aware routing is performed for requests to managed network endpoints for heterogeneous machine learning models. A request to generate an inference is received via a managed network endpoint that invokes a specified machine learning model. Workloads of the different hosts for respective replicas of the machine learning model are evaluated to select one of the hosts to perform the request.

A system generates a recommendation that includes at least one action to address at least one root cause anomaly that causes other anomalies occurred within a distributed system. The at least one root cause anomaly is determined by at least using a graph that represents the distributed system and metrics that are associated with the distributed system.

Addressing root cause anomaly

A system obtains a graph representing a set of resources of a distributed system. At least one node of the graph represents a resource-metric pair. The system further obtains time series data that indicates anomalies from the system. Then, the system determines a root cause anomaly that caused other anomalies based at least in part on the graph and the time series data.

Systems and methods to analyze root cause anomaly

Features are provided for the asynchronous transmission of media files that are part of, or otherwise associated with, user-created content posts. The media file transmissions are asynchronous in nature because the media files are transmitted in parallel background processes while users continue creating content posts or performing other computing tasks. The client devices on which the media file transmissions are initiated can manage the establishment of connections to a network-accessible content management system, and also manage the continued transmission of the media files to the content management system while the users perform other tasks using the client devices.

Management of asynchronous content post and media file transmissions

Features are provided for proactively grouping content for personalized content feeds based on the expected relevance of the content to groups or classes of users. Such proactive grouping can allow personalized (or semi-personalized) content feeds to be delivered with low user-perceived latency. The proactive grouping may be used in conjunction with a more computationally-intensive and higher-latency process for generating personalized feeds. A user's content feed may be provided using a two-phase delivery process in which an initial set of content for the feed is provided from the proactively grouped content collection with which the user is associated. While the user is viewing the initial set of content, the second phase of the delivery process may be performed in which additional content is selected specifically for the user.

Popularity-based content feed management system

Features are provided for the use of persistent connections and efficient content synchronization in content delivery environments. A content management system may provide content feeds to user devices using a persistent duplex connection over which the content management system and user devices may communicate asynchronously. By using a persistent duplex connection to asynchronously communicate with user devices, the content management system can provide content for the content feeds while, in parallel, receiving requests and commands from the user devices, responding to the requests and commands, and transmitting other requests and commands to the user devices. In addition, the content management system and a particular user device can exchange information regarding the content items that the user device has or should have already received.

Persistent duplex connections and communication protocol for content distribution

Disclosed are various embodiments for facilitating gift campaigns in association with a social networking system. A computing device may identify a user of a social networking system that is associated with a recipient for a gift campaign. An invitation for the user to participate in the gift campaign can be transmitted by the computing device. The computing device may identify a product as a suggested gift for the gift campaign. In addition, the computing device may generate content for a network page for the social networking system, and the network page can include a user interface container in which the product is represented. The computing device may also obtain a selection of the product made via the network page and perform a transaction to order the product for the recipient.

Management of asynchronous media file transmissions

Techniques for determining a dynamic data feed may be provided. For example, a system may receive interaction data associated with one or more connection identifiers (e.g., interactions between one or more user accounts and one or more items, including one user interacting with a social network profile of another user, providing a review for an item after purchase, providing a rating associated with the item, adding an item to a wish list, a user sending a communication to another user, etc.). One or more cards may be generated based at least in part on the interaction data, and include information about the one or more users associated with the one or more connection identifiers and the item. The cards may be sorted, aggregated, or filtered and/or provided for presentation.

Determining a dynamic data feed

Transaction data is written to one or more records in a datastore using key-value pairs. The record key for a record comprises a hash key and a range key, where the hash key corresponds to a particular transaction and the range key corresponds to a transaction type. The record key also comprises a counter to distinguish between different records storing data for the same transaction. A serialized data stream of transaction data may be apportioned into multiple data records and stored in a non-relational datastore. Each record for a transaction is individually readable, independently of the other records for the transaction. Accordingly, data records storing a large amount of transaction data for a transaction may be individual retrieved and presented at an access device, enabling a paginated view of the large amount of data with low latency in its retrieval.

Scalable data storage and retrieval

In various embodiments, a content provider may provide interactive content that is a part of a social networking service. One or more frames may be embedded within the interactive content, where the one or more frames may be provided by a payment application. The payment application may be configured to enable a user to view a list of friends; enable the user to select (i) a fund amount and (ii) a friend from the list of friends to transfer the fund amount from the user to the friend; and communicate, by bypassing the content provider, with a payment host to transfer the fund amount from the user to the friend without additional information about the friend.

Efficient synchronization of locally-available content

Representations of authentication objects are selectable through a user interface, such as through a drag and drop operation. When an authentication object is selected by a user, a corresponding authentication object (e.g., in the form of an authentication claim) is transmitted to s system for authentication. The authentication object may contain information that is sufficient for authentication with the system and the information may include an attestation to the state of a computing environment from which the authentication object is transmitted.

Authentication objects with attestation

Representations of authentication objects are provided for selection via an interface. An authentication object may be generated to include information proving possession of a user of an item, such as a one-time password token or a physical trait. A selected authentication object may contain information sufficient for authentication with a corresponding system. The interface may provide multiple representations of authentication objects that are usable with different service providers.

Strong authentication using authentication objects

The use of a mobile device with a merchant application may enable the merchant to turn the mobile device into a point-of-sale terminal that interfaces with a server. The server may receive from the mobile device a transaction via a network, in which the transaction includes transaction details for a purchase request made by a customer. In turn, the server may transmit a transaction token that identifies the transaction to the mobile device of the merchant. Subsequently, the server may receive the transaction token from a client device of the customer. The transaction token being transmitted from the mobile device to the client device using a short range communication that is independent of the network. After receiving the transaction token, the server may provide the transaction details of the transaction that matches the transaction token to the client device for display so that the customer may pay for the transaction.
