    Abstract: A method of implementing sub-table replication starts with the processor detecting an update to an entitlements table. The processor performs filtering of a data table based on the update to the entitlements table. The data table including an entitlements column. The processor detects an update to the entitlements column and performs incremental replication of the data table by causing a version-based replication to be executed. Other embodiments are also described herein.

  • Publication number: 20240004901
    Abstract: 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.

  • Publication number: 20230409431
    Abstract: 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.

  • Publication number: 20230297590
    Abstract: 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.

  • Publication number: 20230297591
    Abstract: Various embodiments provide for replicating a share across deployments of a data platform, where the share can be on a source deployment and the share can be replicated on one or more target deployments, and where the share is replicated with one or more database objects of the source deployment associated with the share. Some embodiments analyze the share to be replicated and, based on the analysis, determine one or more database objects that would be replicated to the one or more target deployments to enable a replica of the share on the one or more target deployments.

  • Publication number: 20230244695
    Abstract: A system for sub-table replication within a materialized view of a source data table. A materialized view of a source data table is generated based on a query, the source data table having a plurality of data table rows associated with a plurality of client identifiers and including an entitlements column and data content, the entitlements column including a plurality of provider account identifiers and a plurality of consumer account identifiers. An update to an entitlements table of the source data table is detected where the entitlements table includes a plurality of entitlements table rows and where the entitlements table rows are associated with the client identifiers, the consumer account identifiers, and the provider account identifiers. An update to the source data table based on the first update to the entitlements table is detected, and an incremental replication of the materialized view of the source data table is performed.

  • Publication number: 20230214405
    Abstract: The embodiments described herein provide means for replicating external stages between deployments of e.g., a cloud data lake using a modified storage integration. The modified storage integration may be defined with a set of storage locations, wherein the storage integration comprises a base URL for each of the set of storage locations and wherein each storage location identifies a remote deployment where a cloud platform is hosted and a geographic region of the remote deployment. An external stage object may be bound to the storage integration, wherein the external stage object facilitates a data loading operation that is currently in progress on the first storage location. In response to detecting an outage at the first storage location, the data loading operation that was in progress on the first storage location may be continued at the second storage location using the storage integration.

  • Patent number: 11620307
    Abstract: Described herein are techniques for replicating external stages between deployments of e.g., a cloud data lake using a modified storage integration. The modified storage integration may be defined with multiple storage locations that it can point to, as well as a designation of an active storage location. The storage integration may also be defined with base file paths for each storage location as well as a relative file path which together may serve to synchronize data loading operations between deployments when e.g., a fail-over occurs from one deployment to another. The storage integration may be replicated from a first deployment to a second deployment, and when database replication occurs, an external stage may be replicated to the second deployment and bound to the replicated storage integration. Thus, a fail-over to the second deployment may result in a seamless transition of data loading processes to the second deployment.
