Techniques for distributed database storage utilizing split volume types for redo log records and change log records are described. A database engine sends redo log data to a first set of page storage nodes and change log data to a second set of tuple storage nodes, where the change log data is stored in an indexed manner Client access to change log data may be provided through a separate set of streaming storage servers instead of through the database engine.

Streaming database change data from distributed storage

An agent can be installed that is separate from an unsecure application, such as a third party browser, executing on a client device. Content to be displayed by, or accessible to, the application can be rendered or determined remotely, such that only unrestricted data is received by the application. Restricted data to be stored on the device, as may include one or more authentication credentials, can be transmitted over a secure connection to the agent, which can store the sensitive information to a secure location on the client device that is inaccessible to the application. Such management allows the sensitive information to be stored on the client device and provided with requests for restricted data, for example, while preventing the restricted data from being exposed to the application on the client device.

Providing content including sensitive data

Technology for generating thumbnail images is provided. In one example, a thumbnail image generation method may include receiving a request to generate a thumbnail image of an electronic page. The electronic page may be analyzed to identify content features of the electronic page. A determination of changes to make to a copy of the electronic page may be made based on the content features to form a modified electronic page. The thumbnail image for the electronic page may be generated using at least a portion of the modified electronic page.

Thumbnail image generation

Techniques for scroll positioning of electronic documents, such as web pages, using element association are described. One or more first document elements associated with a first scroll position of a first document version may be determined. One or more first data representations of the one or more first document elements may then be generated. One or more second document elements may then be determined from within a second (i.e., reloaded) document version. One or more second data representations of the one or more second document elements may then be generated. At least one association between at least one of the one or more first data representations and at least one of the one or more of the second data representations may then be determined. A second scroll position for display of the second document version may then be determined based, at least in part, on the at least one association.

Scroll positioning using element association

Techniques for browser-based workflows are described herein. In some examples, various actions performed within a web browsing application may be tracked. The tracked actions may include actions such as entering a page address, loading a page, entering a search term, entering identity authentication information, selecting a link, selecting an input element, and other actions. A set of actions included within the tracked actions may be selected for association with a workflow, for example based on a determination that the set of actions has been performed at least twice. In some examples, the set of actions associated with the workflow may include loading a page and performing one or more actions on the loaded page. Information indicating the workflow and its associated set of actions may be stored. Upon receiving a request to execute the workflow, the information may be retrieved, and the associated set of actions may be performed.

Browser-based workflows

A higher quality image can be presented in response to a resize action by using the resized image as a starting point for a progressive encoding scheme. A system that provided the image content can resize a copy of the original image in order to have a copy of the resized image. The system can encode a new image of the target size using a wavelet encoding algorithm, and can compare the resized version to one or more of the intermediate decoded versions produced by the encoding scheme. Upon finding a similar intermediate version, the server can provide the remaining transformation passes to be applied to the resized version previously provided. A correction pass can also be executed that applies a filter or post-processing algorithm to reduce the delta between desired output and the output from the transformation.
