Abstract: The subject technology receives a command to commit a table in a different table format on an external volume. The subject technology generates a first snapshot of the table on internal storage. The subject technology generates a first list of metadata files on the internal storage. The subject technology generates, based on the first list of metadata files, a first set of metadata files on the internal storage. The subject technology generates a second snapshot of the table on the external volume. The subject technology generates a second list of metadata files on the external volume. The subject technology generates, based on the second list of metadata files, a second set of metadata files on the external volume. The subject technology generates a first set of data files in a different file format on the external volume.

Abstract: An in-database application package and application instance for a data platform. The data platform creates an application instance of an application package having a versioned schema, creates one or more system roles for the application instance, creates a user role and an administrator role for the application instance, creates one or more objects of the application instance based on a versioned schema, and grants one or more use privileges to the one or more roles. Application instances of the application package are upgraded or patched on the data platform based on application package versions. To ensure a proper upgrade or patch, the data platform tracks versions of executing objects of application instances in a call context.

CPC classification number: G06F16/213 , G06F16/221
Abstract: The subject technology generates, by a compute service manager, a schema hash value for a new schema version associated with a new schema version value, the schema hash value based on determining a sum of hash values of a set of attributes of value columns, the set of attributes comprises a column identifier, and a logical type of a column. The subject technology stores a mapping of the schema hash value to the new schema version value for a table in a metadata database. The subject technology stores a new schema entry based on the schema hash value, the new schema version value, and a new column for the table in the metadata database, the metadata database storing multiple entries for different schema versions, each entry including a particular schema hash value for mapping to a corresponding schema version from the different schema versions.

Abstract: Example caching systems and methods are described. In one implementation, a method receives a query, at an execution platform, directed to data stored across a plurality of shared storage devices, the execution platform comprising one or more execution nodes, an execution node comprising a plurality of processors. The method processes the query using the one or more execution nodes of the execution platform, and in response to a determination of a change in a number of execution nodes of the execution platform, wherein the change is creating a new execution node, wherein a first subset of the plurality of processors comprises a minimal cache and a second subset of the plurality of processors comprises a cache providing faster input-output operations, reassigns processing of the query, among the changed number of execution nodes of the execution platform.

Abstract: Example resource management systems and methods are described. In one implementation, a resource manager is configured to manage data processing tasks associated with multiple data elements. An execution platform is coupled to the resource manager and includes multiple execution nodes configured to store data retrieved from multiple remote storage devices. Each execution node includes a cache and a processor, where the cache and processor are independent of the remote storage devices. A metadata manager is configured to access metadata associated with at least a portion of the multiple data elements.

CPC classification number: G06F16/27 , H04L63/0272
Abstract: A network device communication system can configure network devices, such as a first database in a multi-tenant deployment and a second database in a private deployment, to send and receive sequence messages, such as replication data, over a channel comprising a plurality of private network nodes. The first database can create a link specifying the data share and the second database. The second database selects the link and a secure area in the private deployment is created into which data is replicated and shared with further accounts in a computationally secure and efficient manner.

Abstract: Providing access to consumer information on a private data exchange is described. In an example, privileges are assigned to a share object, granting access to consumer information obtained from a query against data referenced by a data listing of a data exchange. The data exchange comprises one or more data listings provided by one or more data providers. In response to the share object being added to a list of consumed share objects of a data provider that provided the data listing, a database is generated that references the consumer information based on the share object. Access to the database is granted to the data provider that provided the data listing.

Abstract: A system and method of using stateless nodes to process data of catalog objects. The method includes accessing a catalog object including metadata associated with a dataset. The method includes determining, based on the metadata, whether a stateless node is to process the dataset. The method includes detecting, by one or more processors, a failure associated with the stateless node in response to determining that the stateless node is to process the dataset. The method includes replacing the stateless node with a different node without recreating a particular state.
