Parameters:

• Region (string) – Specified only if the base tables belong to a different Amazon Web Services Region.

• CatalogId (string) –

  [REQUIRED]

  The catalog ID where the table resides.

• DatabaseName (string) –

  [REQUIRED]

  (Required) Specifies the name of a database that contains the table.

• Name (string) –

  [REQUIRED]

  (Required) Specifies the name of a table for which you are requesting metadata.

• AuditContext (dict) –

  A structure containing Lake Formation audit context information.

  • AdditionalAuditContext (string) –

    A string containing the additional audit context information.

  • RequestedColumns (list) –

    The requested columns for audit.

    • (string) –

  • AllColumnsRequested (boolean) –

    All columns request for audit.

• SupportedPermissionTypes (list) –

  [REQUIRED]

  Indicates the level of filtering a third-party analytical engine is capable of enforcing when calling the GetUnfilteredTableMetadata API operation. Accepted values are:

  • COLUMN_PERMISSION - Column permissions ensure that users can access only specific columns in the table. If there are particular columns contain sensitive data, data lake administrators can define column filters that exclude access to specific columns.

  • CELL_FILTER_PERMISSION - Cell-level filtering combines column filtering (include or exclude columns) and row filter expressions to restrict access to individual elements in the table.

  • NESTED_PERMISSION - Nested permissions combines cell-level filtering and nested column filtering to restrict access to columns and/or nested columns in specific rows based on row filter expressions.

  • NESTED_CELL_PERMISSION - Nested cell permissions combines nested permission with nested cell-level filtering. This allows different subsets of nested columns to be restricted based on an array of row filter expressions.

  Note: Each of these permission types follows a hierarchical order where each subsequent permission type includes all permission of the previous type.

  Important: If you provide a supported permission type that doesn’t match the user’s level of permissions on the table, then Lake Formation raises an exception. For example, if the third-party engine calling the GetUnfilteredTableMetadata operation can enforce only column-level filtering, and the user has nested cell filtering applied on the table, Lake Formation throws an exception, and will not return unfiltered table metadata and data access credentials.

  • (string) –

• ParentResourceArn (string) – The resource ARN of the view.

• RootResourceArn (string) – The resource ARN of the root view in a chain of nested views.

• SupportedDialect (dict) –

  A structure specifying the dialect and dialect version used by the query engine.

  • Dialect (string) –

    The dialect of the query engine.

  • DialectVersion (string) –

    The version of the dialect of the query engine. For example, 3.0.0.

• Permissions (list) –

  The Lake Formation data permissions of the caller on the table. Used to authorize the call when no view context is found.

  • (string) –

• QuerySessionContext (dict) –

  A structure used as a protocol between query engines and Lake Formation or Glue. Contains both a Lake Formation generated authorization identifier and information from the request’s authorization context.

  • QueryId (string) –

    A unique identifier generated by the query engine for the query.

  • QueryStartTime (datetime) –

    A timestamp provided by the query engine for when the query started.

  • ClusterId (string) –

    An identifier string for the consumer cluster.

  • QueryAuthorizationId (string) –

    A cryptographically generated query identifier generated by Glue or Lake Formation.

  • AdditionalContext (dict) –

    An opaque string-string map passed by the query engine.

    • (string) –

      • (string) –

Return type:

            The SELECT query provided by the customer during CREATE VIEW DDL. This SQL is not used during a query on a view ( ViewExpandedText is used instead). ViewOriginalText is used for cases like SHOW CREATE VIEW where users want to see the original DDL command that created the view.

          • ViewExpandedText (string) –

            The expanded SQL for the view. This SQL is used by engines while processing a query on a view. Engines may perform operations during view creation to transform ViewOriginalText to ViewExpandedText. For example:

            • Fully qualified identifiers: SELECT * from table1 -> SELECT * from db1.table1

          • ValidationConnection (string) –

            The name of the connection to be used to validate the specific representation of the view.

          • IsStale (boolean) –

            Dialects marked as stale are no longer valid and must be updated before they can be queried in their respective query engines.

    • IsMultiDialectView (boolean) –

      Specifies whether the view supports the SQL dialects of one or more different query engines and can therefore be read by those engines.

    • Status (dict) –

      A structure containing information about the state of an asynchronous change to a table.

      • RequestedBy (string) –

        The ARN of the user who requested the asynchronous change.

      • UpdatedBy (string) –

        The ARN of the user to last manually alter the asynchronous change (requesting cancellation, etc).

      • RequestTime (datetime) –

        An ISO 8601 formatted date string indicating the time that the change was initiated.

      • UpdateTime (datetime) –

        An ISO 8601 formatted date string indicating the time that the state was last updated.

      • Action (string) –

        Indicates which action was called on the table, currently only CREATE or UPDATE.

      • State (string) –

        A generic status for the change in progress, such as QUEUED, IN_PROGRESS, SUCCESS, or FAILED.

      • Error (dict) –

        An error that will only appear when the state is “FAILED”. This is a parent level exception message, there may be different ``Error``s for each dialect.

        • ErrorCode (string) –

          The code associated with this error.

        • ErrorMessage (string) –

          A message describing the error.

      • Details (dict) –

        A StatusDetails object with information about the requested change.

        • RequestedChange (dict) –

          A Table object representing the requested changes.

        • ViewValidations (list) –

          A list of ViewValidation objects that contain information for an analytical engine to validate a view.

          • (dict) –

            A structure that contains information for an analytical engine to validate a view, prior to persisting the view metadata. Used in the case of direct UpdateTable or CreateTable API calls.

            • Dialect (string) –

              The dialect of the query engine.

            • DialectVersion (string) –

              The version of the dialect of the query engine. For example, 3.0.0.

            • ViewValidationText (string) –

              The SELECT query that defines the view, as provided by the customer.

            • UpdateTime (datetime) –

              The time of the last update.

            • State (string) –

              The state of the validation.

            • Error (dict) –

              An error associated with the validation.

              • ErrorCode (string) –

                The code associated with this error.

              • ErrorMessage (string) –

                A message describing the error.

  • AuthorizedColumns (list) –

    A list of column names that the user has been granted access to.

    • (string) –

  • IsRegisteredWithLakeFormation (boolean) –

    A Boolean value that indicates whether the partition location is registered with Lake Formation.

  • CellFilters (list) –

    A list of column row filters.

    • (dict) –

      A filter that uses both column-level and row-level filtering.

      • ColumnName (string) –

        A string containing the name of the column.

      • RowFilterExpression (string) –

        A string containing the row-level filter expression.

  • QueryAuthorizationId (string) –

    A cryptographically generated query identifier generated by Glue or Lake Formation.

  • IsMultiDialectView (boolean) –

    Specifies whether the view supports the SQL dialects of one or more different query engines and can therefore be read by those engines.

  • ResourceArn (string) –

    The resource ARN of the parent resource extracted from the request.

  • IsProtected (boolean) –

    A flag that instructs the engine not to push user-provided operations into the logical plan of the view during query planning. However, if set this flag does not guarantee that the engine will comply. Refer to the engine’s documentation to understand the guarantees provided, if any.

  • Permissions (list) –

    The Lake Formation data permissions of the caller on the table. Used to authorize the call when no view context is found.

    • (string) –

  • RowFilter (string) –

    The filter that applies to the table. For example when applying the filter in SQL, it would go in the WHERE clause and can be evaluated by using an AND operator with any other predicates applied by the user querying the table.
