A data platform for developing and deploying a user application within a unified security context. The data platform authorizes a first user to use an editor to access source code of a user application based on security policies of a security context and authorizes the first user to use an application and data manager to set usage privileges for a second user to use the user application based on the security policies of the security context. To provide the user application to the second user, the data platform deploys the user application by instantiating a User Defined Function (UDF) server and an application engine of the UDF server within the security context, instantiating the user application as an application of the application engine within the security context, and authorizing access by the user application to databased on the security policies of the security context.

Data platform with unified privileges

Disclosed is an execution information sharing system that writes execution information to a provider target (and other targets) in a secure manner. Execution information generated by an application may be written to a consumer stage, wherein the application is shared by a provider account of a data exchange with a consumer account that executes the application. A consumer exchange service (ES) of the data exchange may send a request to a copy service of the data exchange to copy the execution information from the consumer stage to the provider stage, wherein the consumer ES is a part of the data exchange and is protected from actions of the consumer account. A copy operation may be executed to copy the execution information from the consumer stage to the provider stage using the copy service of the data exchange. The execution information is ingested from the provider stage to a provider table.

Sharing events and other metrics in native applications

A data platform for managing an application as a first-class database object. The data platform includes at least one processor and a memory storing instructions that cause the at least one processor to perform operations including detecting a data request from a browser for a data object located on the data platform, executing a stored procedure, the stored procedure containing instructions that cause the at least one processor to perform additional operations including instantiating a User Defined Function (UDF) server, an application engine, and the application within a security context of the data platform based on a security policy determined by an owner of the data object. The data platform then communicates with the browser using the application engine as a proxy server.

First class database object server application

An anti-abuse system is provided for a data-platform. An anti-abuse scanner of the data-platform detects a creation of an application package by a provider of content to the data platform where the application package includes a set of files for deployment on the data platform. The anti-abuse scanner performs a review o the set of files to detect malicious content where the review is based on a set of analysis rules and generates a deployment decision for the application package based on a result of the review.

Application trust framework

Embodiments of the present disclosure provide a region-specific events account that is used as a central place to store the events shared by consumers of shared applications in that region. For each of a set of provider accounts in a first region, a global account object corresponding to the provider account is replicated to a second region to establish a replicated global account object in the second region. An account data persistence object (DPO) of a first provider account of the set of provider accounts is modified to designate the first provider account as an events account. The events account is a central location within the second region where execution information generated by execution of applications shared with consumer accounts in the second region is stored. The replicated global account object corresponding to the first provider account is updated to designate the first provider account as the events account.

Events account for native app event sharing

A data platform for managing an application as a first-class database object. The data object can include User Interface (UI) components. The data application can be shared by a provider account to a plurality of consumer accounts using a share object and based on grant commands. The consumer accounts can deploy and operate the UI component based on the share object.

User interface framework for web applications

Techniques for configuring event tables include retrieving, by at least one hardware processor of a computing node, log data at a first process of the computing node. The log data is associated with a function executing at a second process of the computing node. The log data is revised using a table stage to generate revised log data. The table stage is configured as a dedicated storage location of the first process. The revising includes a data enrichment process based on metadata associated with execution of the function at the second process. The revised log data is ingested into an event table.

Configuring an event table using computing node processes

Disclosed is an execution information sharing system that duplicates execution information to a provider target (and other targets) as it is being loaded to a consumer target. A first log information object and a second log information object are generated. The first and second log information objects comprise information indicating a consumer target and information indicating a provider target respectively where execution information generated by an application shared with a consumer account of a data exchange is written. A first event unloader and a second event unloader are generated based on the first and second log information objects respectively, wherein the first and second event unloaders are both linked to the application using a mapping. In response to receiving execution information from the application, the execution information is forwarded to the consumer target and the provider target using the first event unloader and the second event unloader respectively.

A versioned schema of a data platform. A process of maintaining a call stack of executing objects of an application package having a versioned schema includes calling, by a first procedure executed by one or more processors, a second procedure of a versioned application instance, and determining, by the first procedure, a version of the second procedure based on a call context. In response to determining that the version of the second procedure is not in the call context, the first procedure determines a current version of the versioned application package adds the current version to the call context as the version of the second procedure.

Loading procedures of versioned schema

An anti-abuse system is provided for a data-platform. An anti-abuse scanner of the data-platform detects a creation of an application package by a provider of content to the data platform where the application package includes a set of files for deployment on the data platform. The anti-abuse scanner performs a review of the set of files to detect malicious content where the review is based on a set of analysis rules and generates a deployment decision for the application package based on a result of the review.

Embodiments of the present disclosure enable users of a data sharing system to build native applications that can be shared with other users of the data sharing system. The native applications can be published and discovered in the data sharing system like any other data listing, and consumers can install them in their local data sharing system account to serve their data processing needs. A provider may define an installation script for installing an application and create a share object to which the installation script may be attached. In response to an imported database being created in a consumer account based on the share object, a native application framework may automatically execute the installation script in the consumer account and may create a set of database roles to manage execution of the application in the consumer account.

Native applications using database roles

Embodiments of the present disclosure provide a region-specific events account that is used as a central place to store the events shared by consumers of shared applications in that region. Use of such an account helps reduce the operational burden of a provider of the applications as they do not need to determine which accounts have shared events for each different consumer. The provider only needs to login to the events account which is in the same region as the consumer and can query all shared events from different applications that are being used in that region. Also, since the provider can designate an events account in each region, the shared events could be directly ingested into the events account without traveling to a different region.

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.

In-database application package and application

Disclosed is an execution information sharing system that duplicates execution information to a provider target (and other targets) as it is being loaded to a consumer target. A consumer account of a data sharing platform executes an application shared with it by a provider account of the platform. Consumer and provider configurations indicating consumer and provider targets respectively are generated. The consumer configuration and provider configurations are provided to an event context to generate a first and second event unloaders respectively, wherein the event context maintains a mapping linking both the first event unloader and the second event unloader to the application. In response to receiving execution information from the application, the first event unloader and the second event unloader are retrieved. The execution information is then written to the consumer target and the provider target using the first event unloader and the second event unloader respectively.
