Abstract: Described herein are systems and methods for providing access to a database in a multi-tenant environment, including the use of a connection pool, and support for efficient connection validation. For example, the system can support a “seconds to trust idle connection” functionality, which enables lazy validation of connections in the connection pool. The seconds to trust idle connection is the time period, expressed, for example, as a number of seconds, within a particular connection usage, that the connection pool trusts that the connection is still viable, and if so will skip a connection validation test before delivering the connection to a requesting application.

Abstract: Techniques are disclosed for collecting and visualizing historical data. Messages can be generated in response to user requests to make changes to activities in an integration flow. Data associated with the message can be collected in order to generate historical data regarding the message. Depending on the integration flow, a predetermined time point for generating the historical data can be obtained, and the historical data can be generated when the predetermined time point occurs.

Abstract: Systems and methods for maintaining a datacenter are provided. A repair component includes modules that are configured to scan the data objects based on the identifiers of the data objects, identify potential issues or concerns with the data objects, and then repair the issues as they are discovered or over time.

Abstract: Techniques and solutions are described for facilitating data archival, including for improving compliance with retention policies and legal requirements. Data objects can be assigned an expiration date based on properties of the data objects and rules associated with such properties. The data objects can be stored in an archive. In some cases, the data objects can be automatically deleted when the expiration date passes. In other cases, the data objects can be manually deleted when the expiration date passes, with deletion not occurring, and an error being generated, if the expiration date has not passed. Unstructured data objects can be associated with structured data objects through association lists, where an association list can be used to delete such unstructured data objects with or without deletion of an associated structured data object, and where the unstructured data objects can be linked with retention policy information of the structured data object.

Abstract: Event information associated with an occurrence of an event in an electronic content management system can be routed to an event information broker of an analytics engine that is configured to maintain data routing continuity by storing the event information in a system memory. The analytics engine can be logically and/or physically separate from the electronic content management system. The broker can separate event information into event topic bins. Messenger listeners can be used to obtain event information and store it in a staging area database for analysis and reporting without interfering with the operations of the electronic content management system.

Abstract: Compositing aware digital image search techniques and systems are described that leverage machine learning. In one example, a compositing aware image search system employs a two-stream convolutional neural network (CNN) to jointly learn feature embeddings from foreground digital images that capture a foreground object and background digital images that capture a background scene. In order to train models of the convolutional neural networks, triplets of training digital images are used. Each triplet may include a positive foreground digital image and a positive background digital image taken from the same digital image. The triplet also contains a negative foreground or background digital image that is dissimilar to the positive foreground or background digital image that is also included as part of the triplet.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for reclaiming one or more portions of storage resources in a computer system serving one or more virtual computing instances, where the storage resources in the computer system are organized in clusters of storage blocks. In one aspect, a method includes maintaining a respective block tracking value for each storage block that indicates whether a call to reclaim the storage block is outstanding; determining, from the block tracking values, a respective cluster priority value for each of the clusters based on a count of storage blocks in the respective cluster for which a call to reclaim is outstanding; and reclaiming a first portion of storage resources in the computer system in accordance with the cluster priority values.

Abstract: The present invention relates to a method for transmitting content in a content-based network and, more particularly, to a content transmission method by which requested content is identified on the basis of a hash value of the requested content so as to be stored only in mapped routers, thereby preventing the same content from being duplicately stored in routers in a regional group such that various types of content can be distributed and stored, and a content request message is directly transmitted only to routers mapped to a hash value of requested content, on the basis of the hash value of the requested content, such that a traffic load, occurring due to the transmission of a content request message by a flooding scheme, can be reduced.
