Patent number: 11966368Abstract: The subject technology selects a particular zone among multiple zones based on a target skew to meet a global balancing of cluster instances. The subject technology deploys a particular type of cluster instance to the particular zone. The subject technology, for each zone from the multiple zones, determines a respective number of cluster instances. The subject technology identifies a second particular type of cluster instance to add based on a total number of the second particular type of cluster instance in the multiple zones and a second total number of the particular type of cluster instance in the multiple zones. The subject technology adds the second particular type of cluster instance to a second particular zone to meet the global balancing of cluster instances in the multiple zones.Type: GrantFiled: May 31, 2023Date of Patent: April 23, 2024Assignee: Snowflake Inc.Inventors: Johan Harjono, Daniel Geoffrey Karp, Rares Radut, Samir Rehmtulla, Arthur Kelvin Shi, Thanakul Wattanawong

Publication number: 20240061709Abstract: Techniques described herein can optimize usage of computing resources in a data system. Dynamic throttling can be performed locally on a computing resource in the foreground and autoscaling can be performed in a centralized fashion in the background. Dynamic throttling can lower the load without overshooting while minimizing oscillation and reducing the throttle quickly. Autoscaling may involve scaling in or out the number of computing resources in a cluster as well as scaling up or down the type of computing resources to handle different types of situations.Type: ApplicationFiled: October 30, 2023Publication date: February 22, 2024Inventors: Johan Harjono, Daniel Geoffrey Karp, Kunal Prafulla Nabar, Rares Radut, Arthur Kelvin Shi

Patent number: 11372820Abstract: The subject technology determines, after a period of time elapses over a periodic segment of time, an imbalance of cluster instances deployed in multiple zones based on a threshold value, the cluster instances including different types of clusters associated with compute service manager instances.

Patent number: 7805676Abstract: Various embodiments of the present invention provide for enhanced calendaring functionality in a collaboration suite application. A mini-calendar display in different views of the collaboration suite application provide for an easy way to view, edit and/or add appointments without needing to open of the calendar in the collaboration suite application. Email messages can be dragged onto days in the mini-calendar to create meeting proposals. Enhanced UI allows for different meetings being having different appearances based on whether they have been accepted, rejected, etc. Multiple calendars can be viewed simultaneously and their cumulative availability for any time slot can be easily seen via a calendar thermometer. Requests for sharing of calendars can be communicated via email messages, and they can be seamlessly responded to within the email message itself.Type: GrantFiled: December 14, 2006Date of Patent: September 28, 2010Assignee: VMware, Inc.Inventors: Roland J.

Patent number: 7596594Abstract: System and method for displaying and/or acting upon email conversations across folders. In one embodiment, email messages are grouped into conversations regardless of the folders in which the messages reside. Such conversations can span multiple folders. In one embodiment, all or some messages from a conversation are displayed, along with the folder associated with each message. In one embodiment, specified actions can be taken upon all messages in a conversation regardless of the folders in which the messages reside. In one embodiment, it can be specified that an action should apply (or not apply) only to messages in select folders, or that the action should apply only to messages matching a search query. Such specifications may be a system-level indication (which may be set by the system developer or administrator) or it may be a user indication (either a default user setting or an explicit user comment).Type: GrantFiled: August 12, 2005Date of Patent: September 29, 2009Assignee: Yahoo!
