Manage Preset assets

Operations on Preset assets (connections, workspaces, collections, charts, datasets).

In general, these should be:

• Created in top-down order (connection, then workspace, then collection, then charts and datasets)
• Deleted in bottom-up order (charts and datasets, then collections, then workspaces, then connections)¹

Connection

2.0.0 1.0.0

A Preset connection requires a name and qualifiedName. For creation, specific settings are also required to distinguish it as a Preset connection rather than another type of connection. In addition, at least one of adminRoles, adminGroups, or adminUsers must be provided.

Java Python Raw REST API

String adminRoleGuid = RoleCache.getIdForName("$admin"); // (1)
Connection connection = Connection.creator( // (2)
        "preset-connection", // (3)
        AtlanConnectorType.PRESET, // (4)
        List.of(adminRoleGuid), // (5)
        List.of("group2"), // (6)
        List.of("jsmith")) // (7)
    .build();
AssetMutationResponse response = connection.save(); // (8)
String connectionQualifiedName = response.getCreatedAssets().get(0).getQualifiedName(); // (9)

1. Retrieve the GUID for the admin role, to use later for defining the roles that can administer the connection.
2. Build up the minimum request to create a connection.
3. Provide a human-readable name for your connection, such as production or development.
4. Set the type of connection to Preset.
5. List the workspace roles that should be able to administer the connection (or null if none). All users with that workspace role (current and future) will be administrators of the connection. Note that the values here need to be the GUID(s) of the workspace role(s). At least one of adminRoles, adminGroups, or adminUsers must be provided.
6. List the group names that can administer this connection (or null if none). All users within that group (current and future) will be administrators of the connection. Note that the values here are the name(s) of the group(s). At least one of adminRoles, adminGroups, or adminUsers must be provided.
7. List the user names that can administer this connection (or null if none). Note that the values here are the username(s) of the user(s). At least one of adminRoles, adminGroups, or adminUsers must be provided.
8. Actually call Atlan to create the connection.
9. Retrieve the qualifiedName for use in subsequent creation calls. (You'd probably want to do some null checking first.)

Note that the values here need to be the GUID(s) of the workspace role(s). At least one of adminRoles, adminGroups, or adminUsers must be provided.
7. List any groups that can administer this connection. All users within that group (current and future) will be administrators of the connection. Note that the values here are the name(s) of the group(s). At least one of adminRoles, adminGroups, or adminUsers must be provided.

Access policies

Atlan creates the policies that grant access to a connection, including the ability to retrieve the connection and to create assets within it, asynchronously. It can take several seconds (even up to approximately 30 seconds) before these are in place after creating the connection.

You may therefore need to wait before you'll be able to create the assets below within the connection.

To confirm access, retrieve the connection after it has been created. The SDKs' retry loops will automatically retry until the connection can be successfully retrieved. At that point, your API token has permission to create the other assets.

Note: if you are reusing an existing connection rather than creating one via your API token, you must give your API token a persona that has access to that connection. Otherwise all attempts to create, read, update, or delete assets within that connection will fail due to a lack of permissions.

A Preset workspace requires a name and a qualifiedName. For creation, you also need to specify the connectionQualifiedName of the connection for the workspace.

Available relationships

Every level of the business intelligence structure is an Asset, and can therefore be related to the following other assets.

erDiagram
  Asset }o--o{ AtlasGlossaryTerm : meanings
  Asset ||--o{ Link : links
  Asset ||--o| Readme : readme
  Asset }o--o{ Process : inputToProcesses
  Asset }o--o{ Process : outputFromProcesses

AtlasGlossaryTerm

A glossary term provides meaning to an asset. The link terms to assets snippet provides more detail on setting this relationship.

Link

A link provides additional context to an asset, by providing a URL to additional information.

Readme

A README provides rich documentation for an asset. The add asset READMEs snippet provides more detail on setting this relationship.

Process

A process provides lineage information for an asset. An asset can be both an input and an output for one or more processes. The lineage snippets provide more detail on creating and working with lineage.
