Abstract: The described technology is generally directed towards storing an object in different ways based upon evaluating the object's size information. An object classified as small with respect to a threshold size value is an embedded object, and has its object metadata and object data stored in an object table that generally references object data. A non-embedded object can be further classified based on its object metadata size, as a normal object (metadata size below a threshold size) or an inflated object (metadata size not below the threshold size). A normal object has its object data stored in a repository (in a chunk in a chunk store) and its object metadata and pointer to the chunk stored in the object table. An inflated object has its object metadata and object data stored in the repository (in a chunk) with a pointer to the chunk stored in the object table.

Episodic images for the video content are selected from among the episodic image candidates using one or more episodic image selection rules. In some cases, a number of the episodic images are filtered out, for example, as being too similar to each other or for failing to be distinguishable from episodic images of other content. The episodic images are provided for use as representative images for the video content.

Abstract: A network traffic monitoring service provides a way to search network traffic intercepted by a network firewall while protecting the privacy of non-matching network traffic that traverses the firewall. Network traffic is parsed and processed into a set of tokens. In various implementations, the tokens may be words, HTML tags, data values, or other searchable units of information. The tokens are converted into a set of hashes, and the set of hashes is provided to the traffic monitoring service. A search authority submits a search request to the traffic monitoring service. Search terms of the search request are converted to a set of hashes to produce a hashed search request. The traffic monitoring service processes the hashed search request against the set of hashes provided by the network firewall to determine whether the network traffic represented by the set of hashes matches the search request.
