Patent number: 11943203Abstract: A method includes selecting, by at least one hardware processor of a first database deployment, data for transmission to a second database deployment. The data includes a plurality of files forming a data stream. At least a first file of the plurality of files is encoded using a first encryption key which is stored in at least a second file of the plurality of files. The at least a first file is further encoded to include a second encryption key associated with at least a third file of the plurality of files. A set of nodes is identified in a virtual private network connected to the first and second database deployments. The data stream is transmitted from the first database deployment to the second database deployment via the set of nodes of the virtual private network that is connected to the first database deployment and the second database deployment.Type: GrantFiled: November 15, 2022Date of Patent: March 26, 2024Assignee: Snowflake Inc.Inventors: Robert Bengt Benedikt Gernhardt, Mikhail Kazhamiaka, Eric Robinson, Rodney Weaver

Publication number: 20240004901Abstract: A system for data object replication includes at least one hardware processor and at least one memory storing instructions. The instructions cause the at least one hardware processor to perform operations including parsing a replication request to obtain a data object and identification information identifying a set of databases at a first deployment of a data provider. A dependency of the data object to one or more additional data objects stored in the set of databases is detected. A sequential replication of the data object and the one or more additional data object from the first deployment to a second deployment of the data provider is performed. The second deployment is identified by the replication request. A sequence of the sequential replication is based on the detected dependency.Type: ApplicationFiled: September 15, 2023Publication date: January 4, 2024Inventors: Robert Bengt Benedikt Gernhardt, Chao-Yang Lo, Nithin Mahesh, Subramanian Muralidhar, Sahaj Saini

Patent number: 11860896Abstract: A system for data object replication includes at least one hardware processor and at least one memory storing instructions. The instructions cause the at least one hardware processor to perform operations including decoding a replication request to obtain a data object. Object dependencies associated with the data object and a plurality of additional data objects are determined. A replication sequence of the data object and the plurality of additional data objects is determined based on the object dependencies. A replication of the data object and at least one of the plurality of additional data objects is performed according to the replication sequence.

Publication number: 20230409431Abstract: This disclosure provides methods and techniques of data replication involving cross replication group (RG) references. The present disclosure avoids automatic replication failing when an entity in an RG refers to another entity external to the RG. The entity to be replicated within the RG is referred to as the “referring entity,” and the entity as the dangling reference is referred to as the “referred entity.” Although the referring and referred entities are not replicated together in a replication operation, the referred entity may have already been replicated to the target account in another replication operation on a different replication group. In such cases, the data replication procedure may, according to aspects of the present disclosure, check if the referred entity has already been replicated, and if so, proceed to replicate the referring entity without fail, and link the referring and referred entities to enable normal functioning of the referring entity.Type: ApplicationFiled: July 10, 2023Publication date: December 21, 2023Inventors: Robert Bengt Benedikt Gernhardt, Nithin Mahesh, Sahaj Saini, Matthew Uhlar

Publication number: 20230401229Abstract: The distributed database can implement unstructured data replication using an internal or external storage location. Metadata, such as a directory table that lists the unstructured files, can be replicated across different deployments, followed by replication of the staged data. Replicating the staged data can be implemented by replication of only the stage metadata or replication of the database files between the deployments.Type: ApplicationFiled: November 1, 2022Publication date: December 14, 2023Inventors: Robert Bengt Benedikt Gernhardt, Chong Han, Nithin Mahesh, Aravind Ramarathinam, Saurin Shah, Yanrui Zhang

Publication number: 20230344796Abstract: Different database deployments, or other data system deployments, may want to communicate with each other without sacrificing security or control. To this end, embodiments of the present disclosure may provide secure message exchange techniques for a source and/or target deployment. Configurable rule sets may be stored in the deployments; the rule sets may define what messages may be communicated between deployments. The deployments may implement a selective filtering scheme in one or more stages based on the rule sets to filter outgoing and/or incoming messages.Type: ApplicationFiled: June 27, 2023Publication date: October 26, 2023Inventors: Robert Bengt Benedikt Gernhardt, Mikhail Kazhamiaka, Nithin Mahesh, Eric Robinson

Publication number: 20230297590Abstract: A method includes generating at a source account of a database system user, a replication group object (RGO). The RGO includes a manifest identifying one or more data object types and one or more databases. A replication of data objects of the one or more data object types is performed from the one or more databases to a target account of the database system user. The replication of the data objects is performed as a unit. The RGO is replicated as a failover group object (FGO) within the target account of the database system user. A network failure is detected at the source account of the database system user. The target account of the database system user is promoted as a new source account based on the detecting of the network failure.Type: ApplicationFiled: May 24, 2023Publication date: September 21, 2023Inventors: Robert Bengt Benedikt Gernhardt, Mikhail Kazhamiaka, Nithin Mahesh, Laxman Mamidi, Subramanian Muralidhar, Vishnu Dutt Paladugu, Sahaj Saini

Patent number: 11539677Abstract: A networked device communication system can configure network devices (e.g., a primary and secondary database) to send and receive sequences of messages, such as replicated data, using one or more keypairs and wrapping keys. The sequences of messages can include an initial set of messages that are encrypted by a wrapping key, and further include another set of messages that are encrypted by a replaced staggered key. The sequence of messages can be configured to be decrypted without exporting keys of hardware security modules.Type: GrantFiled: March 25, 2022Date of Patent: December 27, 2022Assignee: Snowflake Inc.Inventors: Damien Carru, Robert Bengt Benedikt Gernhardt, Martin Hentschel, Nithin Mahesh, Eric Robinson
