        summary

        Data store federation management allows you to see the administrator for each data store and to authenticate to the data store.
        Also, if you are using multiple Data Catalogs, you can Data Setting which Data Store is displayed by default.

        Data Store Linkage Management Screen

        • Clicking Authentication (Re-authentication) will take you to the authentication screen for the relevant data store.
        • Click on the name of each data store to view the Data Catalog for that data store.
        • Clicking on Data Setting to Default will toggle the datastore that appears by default on the Data Catalog screen.

        Admins and Users
        • Administrator refers to the Data Catalog manager.
          • The Data Catalog administrator retrieves the assets using the credentials of the account used during Data Store integration.
        • User refers to you, the user of the Data Catalog.
          • If the data store has already been authenticated, the account name used during authentication will be displayed.

        New data store linkage

        When a datastore is linked, assets corresponding to that datastore are automatically imported.
        Note that the user newly linked to a datastore becomes the datastore administrator for that datastore.

        Authentication of federated data store

        Authentication to the data store allows the actual data to be viewed based on the authorization of the authentication information.
        For more information, please refer to Viewing Actual Data.

        The user can check whether he/she has been authenticated for each data store in the user section of the data store linkage management screen.
        A datastore without a user value is a datastore that has not yet authenticated itself.

        A data store that has already been certified can be re-certified.

        Re-authentication of Data Catalog administrator

        TROCCO's Data Catalog retrieves assets using the credentials of the account used by the Data Catalog administrator when linking data stores.
        Therefore, if the data store is re-authenticated using different authentication information from the last time the data store was authenticated (generally the first time the data store was linked), the composition of the asset list may change (the assets to be retrieved may change). Please note

        Data Store Authentication Procedure

        The basic procedure is the same whether you are linking a new data store or getting certification for an existing data store.
        However, if you are linking a data store for the first time to any data warehouse, you must authenticate as an administrator.

        For BigQuery

        Select one of the following as the authentication method

        • Google Account (OAuth): Authenticate with your Google account. Please follow the authentication procedure according to the screen displayed.
        • Service account (JSON key): Authenticate using JSON key.

        Authentication with Google Account (OAuth)

        Please allow TROCCO to request access to your Google account.

        When authenticating with a service account (JSON key)

        The procedure for obtaining a JSON Key is the same as the procedure for creating Connection Configuration using a service account.
        However, in order to grant access to the project, the following roles must be granted to the service account

        • BigQuery Job Users
        • BigQuery Data Viewer

        Host name input format

        You can enter the information in one of the following formats
