Patent number: 11297031Abstract: A service enables a command that refers to a file system object using a hierarchical namespace identifier to be executed against the file system object in a flat namespace. The service selectively distributes the command to one of a plurality of name resolution nodes based on a directory name included in the hierarchical namespace identifier. The identified node resolves the directory name to a flat namespace identifier that is used to execute the command against the flat namespace. After communicating with at least one storage node to resolve a directory name, each name resolution node stores a mapping of the directory name to the corresponding flat namespace identifier in a cache, so that subsequent resolutions of that directory name may be performed more efficiently. Cache entries may be invalidated when an operation occurs that impacts the relevant mapping and/or based on system considerations such as cache expiry.Type: GrantFiled: July 6, 2020Date of Patent: April 5, 2022Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Georgi M.

Patent number: 10901796Abstract: In various embodiments, methods and systems for implementing hash-based partitioning in distributed computing systems are provided. At a high level, a distributed computing system having an underlying range-based partitioning architecture for storage may be configured as a hash-based partitioning system, for example, a hybrid range-hash table storage. An operations engine of the hash-based partitioning system receives a tenant request to provision input/output operations per second (IOPS). The tenant request comprises a requested number of IOPS. Based on the tenant request, a provisioning operation to provision IOPS in a hybrid range-hash table storage with hash-based partitioning is determined. The provisioning operation is selected from one of the following: a table creation provisioning operation, an IOPS increase provisioning operation, and an IOPS decrease provisioning operation. The selected provisioning operation is executed for a corresponding table.Type: GrantFiled: June 29, 2018Date of Patent: January 26, 2021Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Shane Mainali, Georgi M. Chalakov, Maneesh Sah, Zichen Sun, Michael E. Roberson, Andrew J. Edwards, Jegan Devaraju, Krishnan Varadarajan

Patent number: 10789217Abstract: Methods, systems, and apparatuses are provided for a storage system that implements a hierarchical namespace service. A storage system includes a plurality of physical nodes and a plurality of sets of virtual nodes. Each set of virtual nodes is managed by a corresponding physical node. Each virtual node is configured to manage a respective set of directory blocks. Each directory block is a respective partition of a storage namespace and is managed by a corresponding single virtual node. Each virtual node maintains a directory block map. The directory block map maps file system object names in a hierarchical namespace to entity block identifiers in the flat namespace for entity blocks (files and folders) stored in directories corresponding to the managed set of directory blocks. Load balancing may be performed by moving virtual nodes between physical nodes, and by splitting directory blocks.Type: GrantFiled: June 22, 2018Date of Patent: September 29, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Georgi M.

Publication number: 20100195139Abstract: Print rendering verification is described. In embodiments, a PDL (Page Description Language) print file can be received where the PDL print file is generated when a print job of a printable image is initiated. A raster image can then be generated from the PDL print file. The raster image can be compared to a reference image that corresponds to the raster image, where the reference image is a comparative standard by which to evaluate print quality of the printable image. A determination can then be made as to whether the printable image is an acceptable quality based on the comparison of the raster image to the reference image.Type: ApplicationFiled: February 4, 2009Publication date: August 5, 2010Applicant: MICROSOFT CORPORATIONInventors: Mariyan D.
