Patent number: 12271278Abstract: In some embodiments, a database cluster to cluster synchronization system may include multiple replicators coupled to a source database cluster and a destination database cluster, where the source and destination cluster may be shard clusters. Each of the multiple replicators may correspond to a respective subset of the source database cluster and configured to monitor changes of data on the respective subset of the source database cluster and translate the changes of data to one or more database operations to be performed on the destination cluster. The changes of data on the source database may be contained in respective change streams associated with each of the replicators.Type: GrantFiled: June 5, 2023Date of Patent: April 8, 2025Assignee: MongoDB, Inc.Inventors: Ryan Chipman, Lingzhi Deng, Tim Fogarty, Max Jacob Hirschhorn, Samyukta Lanka, Judah Schvimer, Andrew Michalski Schwerin, Randolph Tan, Mark Porter

Patent number: 11893042Abstract: A method is provided for resharding a sharded database sharded according to a first shard key. The method includes: receiving, by a processor an instruction to reshard the sharded database; receiving, at the processor, a new shard key to be used in a resharding process to reshard the sharded database; determining, by the processor, whether a duration of unavailability of the sharded database during the resharding process is less than a predetermined amount of time; and automatically performing, by the processor, the resharding process according to the new shard key to produce a resharded database, if the duration of unavailability is less than the predetermined amount of time. The method may be performed without users noticing a significant interruption to read/write operations from/to the database.Type: GrantFiled: July 1, 2022Date of Patent: February 6, 2024Assignee: MongoDB, Inc.Inventors: Mark Porter, Max Jacob Hirschhorn, Daniel William Gottlieb, Garaudy Etienne, Andrew Michalski Schwerin, Judah Schvimer, Siyuan Zhou, Kaloian Manassiev, Esha Maharishi

Publication number: 20230393900Abstract: A database system may use asymmetric hardware for analytics nodes. In some embodiments, a database system includes a replica set comprising a plurality of base nodes and at least one analytics node. The analytics nodes may have asymmetric hardware respective to the base nodes. The base nodes may include a primary node and two secondary nodes. The primary node may be configured to accept writes and propagate the writes to secondary nodes and may also propagate writes to analytics nodes. Secondary nodes may replicate writes and accept reads. Analytics nodes may perform data analysis operations. Analytics nodes may have a first instance size different than a second instance size of the base nodes.Type: ApplicationFiled: June 5, 2023Publication date: December 7, 2023Applicant: MongoDB, Inc.Inventors: Karen Lin, Harish Salem Chandramowli, Augustin Liebster, Robert Liles, Cory P.

Publication number: 20230020330Abstract: According to aspects of the disclosure, there is provided a scalable cloud distributed database system for hosting data of multiple database tenants. In some embodiments, the database may be serverless. The serverless database may be configured to automatically and dynamically match resources to workload demands for tenants of the database. Databases described herein may include replica sets hosting multiple tenants. Tenants may be migrated from one replica set to another replica set based on usage. Usage of tenants may be throttled during migration between replica sets. Tenants with lower usage may be selected for migration between replica sets. During migration, files containing both a document and a history of updates to the document may be migrated. Databases described herein may include multiple storage tiers having different read and/or write speeds.Type: ApplicationFiled: July 1, 2022Publication date: January 19, 2023Applicant: MongoDB, Inc.Inventors: Andrew Michalski Schwerin, Therese Avitabile, Mark Porter, Tomer Yakir, Gregory Banks, Louisa Berger, Jack Wearden, Judah Schvimer, Matthew Russotto, Michael Cahill, Esha Maharishi, Siyuan Zhou, Eric Andrew Milkie, A.

Publication number: 20160089846Abstract: A continuously extruded seamless PVC pipe shrinks to about 50% of its extruded size when reheated to a specific temperature. Prior to shrinking, the extruded pipe is slid over a wooden piling, dimensional lumber, railroad tie or other metal or wood substrate. Upon application of heat, the pipe will shrink to encapsulate the substrate in a hermetically sealed, durable membrane. This impervious membrane will prevent any attack on the substrate by boring and surface destroying organisms and substances.Type: ApplicationFiled: June 23, 2014Publication date: March 31, 2016Applicant: Shoreline Plastic, LLCInventors: Stafford McCartney, Mark Porter

Patent number: 8247615Abstract: The present invention is concerned with a process to convert xanthophyll esters derived from Capsicum sources to their free (non-esterified) forms. The present invention is concerned with a process for obtaining Capsicum derived xanthophylls that meet the finished product needs for purity, yield, ease of use, industrial compatibility and cost that are required to make product suitable for the nutritional supplement, food and beverage industries. The present invention is concerned with a process which yields from 60 to 80%, of xanthophyll materials and nearly quantitative recovery of all input xanthophylls, which xanthophylls are of high purity. The present invention concerns a method to obtain xanthophyll esters present almost exclusively in the trans form when isolated from the natural plant sources. The present invention concerns a process to re-convert cis product back to the more desired trans form.Type: GrantFiled: May 14, 2010Date of Patent: August 21, 2012Assignee: Kalamazoo Holdings, Inc.Inventors: Mark Reilly, Josh James Tuinstra, Lucas Chadwick, Mark Porter, James Barren, Gregory S.
