Amazon S3

The Amazon S3 connector provides SQL access to Amazon S3 Buckets and objects.

Before you begin

Before using the Amazon S3 connector, do the following tasks:

  • In your Google Cloud project:
    • Grant the roles/connectors.admin IAM role to the user configuring the connector.
    • Grant the following IAM roles to the service account that you want to use for the connector:
      • roles/secretmanager.viewer
      • roles/secretmanager.secretAccessor

      A service account is a special type of Google account intended to represent a non-human user that needs to authenticate and be authorized to access data in Google APIs. If you don't have a service account, you must create a service account. For more information, see Creating a service account.

    • Enable the following services:
      • secretmanager.googleapis.com (Secret Manager API)
      • connectors.googleapis.com (Connectors API)

      To understand how to enable services, see Enabling services.

    If these services or permissions have not been enabled for your project previously, you are prompted to enable them when configuring the connector.

Configure the connector

Configuring the connector requires you to create a connection to your data source (backend system). A connection is specific to a data source. It means that if you have many data sources, you must create a separate connection for each data source. To create a connection, do the following steps:

  1. In the Cloud console, go to the Integration Connectors > Connections page and then select or create a Google Cloud project.

    Go to the Connections page

  2. Click + Create new to open the Create Connection page.
  3. In the Location section, choose the location for the connection.
    1. Region: Select a location from the drop-down list.

      Supported regions for connectors include:

      For the list of all the supported regions, see Locations.

    2. Click Next.
  4. In the Connection Details section, complete the following:
    1. Connector: Select Amazon S3 from the drop down list of available Connectors.
    2. Connector version: Select the Connector version from the drop down list of available versions.
    3. In the Connection Name field, enter a name for the Connection instance.

      Connection names must meet the following criteria:

      • Connection names can use letters, numbers, or hyphens.
      • Letters must be lower-case.
      • Connection names must begin with a letter and end with a letter or number.
      • Connection names cannot exceed 49 characters.
    4. Optionally, enter a Description for the connection instance.
    5. Optionally, enable Cloud logging, and then select a log level. By default, the log level is set to Error.
    6. Service Account: Select a service account that has the required roles.
    7. Optionally, configure the Connection node settings:

      • Minimum number of nodes: Enter the minimum number of connection nodes.
      • Maximum number of nodes: Enter the maximum number of connection nodes.

      A node is a unit (or replica) of a connection that processes transactions. More nodes are required to process more transactions for a connection and conversely, fewer nodes are required to process fewer transactions. To understand how the nodes affect your connector pricing, see Pricing for connection nodes. If you don't enter any values, by default the minimum nodes are set to 2 (for better availability) and the maximum nodes are set to 50.

    8. AWS Region: Region where your Amazon S3 instance is hosted
    9. Optionally, click + Add label to add a label to the Connection in the form of a key/value pair.
    10. Click Next.
  5. In the Destinations section, enter details of the remote host (backend system) you want to connect to.
    1. Destination Type: Select a Destination Type.
      • Select Host address from the list to specify the hostname or IP address of the destination.
      • If you want to establish a private connection to your backend systems, select Endpoint attachment from the list, and then select the required endpoint attachment from the Endpoint Attachment list.

      If you want to establish a public connection to your backend systems with additional security, you can consider configuring static outbound IP addresses for your connections, and then configure your firewall rules to allowlist only the specific static IP addresses.

      To enter additional destinations, click +Add destination.

    2. Click Next.
  6. In the Authentication section, enter the authentication details.
    1. Select an Authentication type and enter the relevant details.

      The following authentication types are supported by the Amazon S3 connection:

      • Root credentials
      • AWS IAM Roles
      • AWS Temporary Credentials
    2. To understand how to configure these authentication types, see Configure authentication.

    3. Click Next.
  7. Review: Review your connection and authentication details.
  8. Click Create.

Configure authentication

Enter the details based on the authentication you want to use.

  • Root credentials

    To authenticate using account root credentials.

    • AWS Access Key: The access key of the root user
    • AWS Access Secret: The secret key of the root user
  • AWS IAM Roles

    To authenticate using an AWS IAM role.

    • AWS Access Key: The access key of the IAM user to assume the role for
    • AWS Access Secret: The secret key of the IAM user to assume the role for
    • AWS Role ARN: Specify the Role ARN for the role you'd like to authenticate with. Only credentials for the specified role would be retrieved.
    • AWS External Id: Required only when you assume a role in another account.
  • AWS Temporary Credentials

    To authenticate using temporary credentials

    • AWS Access Key: The access key of the IAM user to assume the role for
    • AWS Access Secret: The secret key of the IAM user to assume the role for
    • AWS Session Token: This is generated alonside the temporary credentials.
    • AWS Role ARN: Specify the Role ARN for the role you'd like to authenticate with. Only credentials for the specified role would be retrieved.
    • AWS External Id: Required only when you assume a role in another account.

Entities, operations, and actions

All the Integration Connectors provide a layer of abstraction for the objects of the connected application. You can access an application's objects only through this abstraction. The abstraction is exposed to you as entities, operations, and actions.

  • Entity: An entity can be thought of as an object, or a collection of properties, in the connected application or service. The definition of an entity differs from a connector to a connector. For example, in a database connector, tables are the entities, in a file server connector, folders are the entities, and in a messaging system connector, queues are the entities.

    However, it is possible that a connector doesn't support or have any entities, in which case the Entities list will be empty.

  • Operation: An operation is the activity that you can perform on an entity. You can perform any of the following operations on an entity:

    Selecting an entity from the available list, generates a list of operations available for the entity. For a detailed description of the operations, see the Connectors task's entity operations. However, if a connector doesn't support any of the entity operations, such unsupported operations aren't listed in the Operations list.

  • Action: An action is a first class function that is made available to the integration through the connector interface. An action lets you make changes to an entity or entities, and vary from connector to connector. Normally, an action will have some input parameters, and an output parameter. However, it is possible that a connector doesn't support any action, in which case the Actions list will be empty.
