A method includes receiving a request to perform a shuffle operation on a data stream; receiving at least a portion of the data stream including a plurality of records, each including a key; storing each of the plurality of records in a persistent storage location assigned to a key range corresponding to keys included in the plurality of records; receiving a request from a consumer for a subset of the plurality of records including a range of keys; and upon receiving the request from the consumer, providing the subset of the plurality of records including the range of keys from the one or more persistent storage locations.

Persistent shuffle system

A method includes receiving a request to perform a shuffle operation on a data stream, the request including a set of initial key ranges: generating a shuffler configuration that assigns a shuffler from a set of shufflers to each of the initial key ranges; initiating the set of shufflers to perform the shuffle operation on the data stream; analyzing metadata statistics to determine whether a shuffler configuration update event occurs, the metadata statistics produced by the set of shufflers during the shuffle operation and indicating load statistics for each shuffler in the set of shufflers; and upon occurrence of the shuffler configuration update event and during the shuffle operation, altering the shuffler configuration based at least in part on the metadata statistics to produce an assignment of shufflers to key ranges that is different from the assignment of shufflers to the initial key ranges.

Dynamic shuffle reconfiguration

A computer based system and method of providing document isolation during routing of a document through a workflow is disclosed. The method comprises maintaining a separate 'working' copy of the original base document while the document is routed through a workflow. Access controls, which define who may access the original document as well as any versions of the working copy document, are defined and stored in relation to the documents. The access controls further define the types of actions users may take with respect to the document. Users are selectively directed to the appropriate document, either the base document or working copy, and selectively granted permission to perform publishing operations on the working copy document, as determined by the access controls.

System and method for document isolation

The subject invention pertains to the integration of an object model and a multidimensional database query language such as MDX. In particular, multidimensional declarative query language entities can be exposed through objects in an object model. The object model enables generation and employment of procedural language functions, routines, or procedures that interact with multidimensional database data. This effectively provides an extension for multidimensional query languages. For example, procedures can be stored and invoked from a declarative language query. Furthermore, the object model disclosed herein can expose a context object to enable conditional procedures based on the context of execution.

Multidimensional database query extension systems and methods

Trace and replay objects can be designed to automatically perform operations concerning database trace data upon invocation by custom computer processes. Trace data can be saved to any of variety of locations. It can be manipulated for the purpose of storage or replay. Trace data can be played back against any database server using numerous replay configuration options. Replay notifications allow data to be changed just before it is submitted to a database for execution, and allow immediate examination of replay results and validation of playback correctness. Thus, trace and replay objects greatly simplify manageability of trace data. Custom processes can now completely automate security audit and health monitoring of traced database servers. Automatic verification of new server releases and security packs can also be performed. Custom processes can use the provided objects to flexibly access and manipulate the retrieval, storage, and replay of database trace data.
