Patent number: 9626404Abstract: Distributed storage systems support SQL while also providing scalability and fault tolerance by utilizing an SQL library (the SQL execution component) layered on top of a transactional key-value system (the storage component). The SQL library comprises a parser and an execution engine running at the client, while the storage component comprises a key-value system for storing the data. The SQL library parses SQL queries received from client applications and maps them to transactions on the key-value system. The key-value system stores data items identified by key and provides concurrency control mechanisms to handle concurrent transactions. The key-value system may be a distributed system with several storage servers, each attached to one or more storage devices.Type: GrantFiled: January 6, 2016Date of Patent: April 18, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Marcos K. Aguilera, Joshua Leners, Michael Walfish

Patent number: 8671163Abstract: A method of serving content to multiple clients via a network is provided. Independent sessions with each of a plurality of clients are maintained, wherein the number of clients in the plurality of clients can vary over time, and wherein the start of each session and the end of each session can be independent of the start and end of other sessions. A stream of packet payloads is received, each packet payload of the stream of packet payloads including data generated from the content, wherein each packet payload in at least a subset of the stream of packet payloads includes a different set of data. Each packet payload in the stream of packet payloads is transmitted to each client of the plurality of clients in corresponding packets, wherein the packet payload transmitted to a client at any particular time is independent of the state of the corresponding session.Type: GrantFiled: April 18, 2012Date of Patent: March 11, 2014Assignee: Digital Fountain, Inc.Inventors: Michael Luby, Ronen Vainish, Lars Rasmussen, David Kushi, Serban Simu, Adrian Perrig, Roberto Attias, Michael Walfish, Diane Hernek, John Byers

Patent number: 6047300Abstract: Automatically detecting a misspelled word and replacing the misspelled word with a correctly spelled word. Words are automatically spell checked as delimited. If a word is detected as a misspelled word then a correctly spelled alternate word is generated. The misspelled word and the correctly spelled alternate word are compared according to a set of difference criteria. The difference criteria correspond to common types of misspellings. If the misspelled word and the correctly spelled alternate word differ according to a difference criterion then the correctly spelled alternate word is identified as a replacement candidate word. The results of the difference criteria comparisons are reviewed using a set of selection criteria. If the results of the difference criteria comparisons satisfy the selection criteria then one of the replacement candidate words is correctly spelled as a replacement word and the misspelled word is replaced by the replacement word.Type: GrantFiled: May 15, 1997Date of Patent: April 4, 2000Assignee: Microsoft CorporationInventors: Michael Walfish, Dean Hachamovitch, Ronald Andrew Fein
