摘要： A pipeline I/O mechanism in a network redirector that breaks up large files into sections, and sends write (or read) requests for each section in a pipeline fashion to a network file server, without waiting for a response for a previously-sent section. The pipeline I/O mechanism tracks the returned status of each section for which a request was made, so that success or failure of the request is determined as a whole. The pipeline I/O system and method dramatically increase the performance of network remote I/O operations, particularly with file write operations directed to a file on a network file server.

摘要： A “Real-Time-Ready Analyzer” combines a data stream management system (DSMS) with a map-reduce (M-R) framework to construct a streaming map-reduce framework that is suitable for real-time Behavioral Targeting (BT) (or other temporal queries). The Real-Time-Ready Analyzer allows users to write “dual-intent” temporal analysis queries for BT. These queries are succinct and easy to express, scale well on large-scale offline data, and can also work over real-time data. Further, the Real-Time-Ready Analyzer uses the aforementioned streaming map-reduce framework to provide dual-intent algorithms for end-to-end BT phases. Experiments using real data from an advertisement system show that the Real-Time-Ready Analyzer is very efficient and incurs orders-of-magnitude lower development effort than conventional systems.

摘要： Disclosed is a data synchronization service for use in a peer-to-peer computing environment. Selected data objects are copied onto selected computing devices. A service running on each device monitors data objects for changes. When a change is detected, the service sends a change notification to the other devices so that they can update their copies of the data object. A user can access a data object from any device, knowing that he will retrieve the latest version of the data object. Instead of incurring the costs of storing a large file on every device, a user “ghosts” the file on some devices. A ghosting device stores only metadata about the file rather than the entire file. The user accesses the file through the ghost: access requests are sent to a device that holds the actual contents, and those contents are presented to the user as if they were stored locally.

摘要： Large, unstructured objects can be manipulated within a relational database management system (RDBMS). A “filestream” data storage attribute is provided that can be used to tag a column in a relational table. The filestream attribute identifies the data for that column will be stored as a file in the file system in the operating system. The RDBMS manages the creation and deletion of the file in the file system. There is a 1:1 reference between the file in the file system and a cell (intersection of row and column). The data in the filestream column can be manipulated the same way as the data in other columns using a programming language, such as SQL or MICROSOFT®'s T-SQL.

摘要： An improved method and system for client-side caching that transparently caches suitable network files for offline use. A cache mechanism in a network redirector transparently intercepts requests to access server files, and if the requested file is locally cached, satisfies the request from the cache when possible. Otherwise the cache mechanism creates a local cache file and satisfies the request from the server, and also fills in a sparse cached file as reads for data in ranges that are missing in the cached file are requested and received from the server. A background process also fills in local files that are sparse, using the existing handle of already open server files, or opening, reading from and closing other server files. Security is also provided by maintaining security information received from the server for files that are in the cache, and using that security information to determine access to the file when offline.

摘要： The present invention relates to a system and methodology to facilitate interoperability and compatibility between disparate data systems. In one aspect, a file transformation system is provided having at least one file associated with one or more unstructured properties. A file property handler manipulates the unstructured properties in accordance with one or more structured properties associated with a structured object store environment. If an unstructured file is to be operated in the context of a structured object store environment, a promotion operation is performed to update unstructured properties in the file with structured properties suitable for operation in the structured object store environment. If a promoted item were to be manipulated in the structured object store environment, a demotion operation or reverse transformation is performed to update properties in the file.

摘要： The disclosed architecture leverages realtime continuous event processing (CEP) to address using a general input interface framework to import a dynamic set of event types (e.g., assets), and using a declarative, expressive query model to implement monitoring and management tasks on an asset level. This is in contrast to looking separately at single values from static databases and/or realtime streams as is common conventionally. The architecture uses the CEP data model to model assets as realtime event types. Thus, queries can be formulated per asset and not just per single stream. The architecture uses the query capabilities of CEP to formulate asset management and monitoring tasks as standing, declarative queries, and uses the input interface of a CEP platform to correlate data from different data sources with different dynamic properties.
