Patent number: 10229175Abstract: An event tap associated with a server, such as a Web server, at a machine can transform a server event into a tuple, select a database node for the tuple, and place the tuple in a queue for that database node, and then flush the queue periodically directly into database notes. The use of an event tap can thus reduce the computational burden on the database while keeping the server event data in the database relatively fresh.Type: GrantFiled: September 10, 2014Date of Patent: March 12, 2019Assignee: Teradata US, Inc.Inventors: George Candea, Anastasios Argyros, Mayank Bawa

Patent number: 9684554Abstract: A system and method for using failure casting to manage failures in computer system. In accordance with an embodiment, the system uses a failure casting hierarchy to cast failures of one type into failures of another type. In doing this, the system allows incidents, problems, or failures to be cast into a (typically smaller) set of failures, which the system knows how to handle. In accordance with a particular embodiment, failures can be cast into a category that is considered reboot-curable. If a failure is reboot-curable then rebooting the system will likely cure the problem. Examples include hardware failures, and reboot-specific methods that can be applied to disk failures and to failures within clusters of databases. The system can even be used to handle failures that were hitherto unforeseen—failures can be cast into known failures based on the failure symptoms, rather than any underlying cause.Type: GrantFiled: January 11, 2013Date of Patent: June 20, 2017Assignee: Teradata US, Inc.Inventors: George Candea, Mayank Bawa, Anastasios Argyros

Patent number: 8156107Abstract: The present invention addresses the problem of partitioning database relations across a plurality of hosts in a shared-nothing cluster while minimizing communication costs. A new partitioning approach for database relations—join-partitioning—is introduced that focuses on relations and their dependencies to a priori partition the plurality of relations to the plurality of hosts such that each host can locally compute a large class of queries over its partitioned data in isolation at query time, independent of other hosts in the cluster. Such an approach thus overcomes the primary bottleneck, i.e., the network, in deploying database systems over shared-nothing clusters by allowing them to seamlessly scale linearly to tens of thousands of hosts and manage tens or hundreds of terabytes of data.Type: GrantFiled: February 2, 2007Date of Patent: April 10, 2012Assignee: Teradata US, Inc.Inventors: Mayank Bawa, Anastasios Argyros, George Candea

Patent number: 7711727Abstract: A privacy-preserving index system addresses the problem of providing a privacy-preserving search over distributed access-controlled content. Indexed documents can be readily reconstructed from inverted indexes used in the search. The privacy-preserving index system builds a centralized privacy-preserving index in conjunction with a distributed access-control enforcing search protocol. The privacy-preserving index utilizes a randomized algorithm for constructing a privacy-preserving index. The privacy-preserving index is strongly resilient to privacy breaches. The privacy-preserving index system allows content providers to maintain complete control in defining access groups and ensuring its compliance, and further allows system implementors to retain tunable knobs to balance privacy and efficiency concerns for their particular domains.Type: GrantFiled: April 3, 2008Date of Patent: May 4, 2010Assignee: International Business Machines CorporationInventors: Rakesh Agrawal, Mayank Bawa, Roberto J.
