        All REST clients should first call this route to get catalog configuration
        properties from the server to configure the catalog and its HTTP client.
        Configuration from the server consists of two sets of key/value pairs.

        - defaults -  properties that should be used as default configuration; applied before client configuration

        - overrides - properties that should be used to override client configuration; applied after defaults and client configuration


        Catalog configuration is constructed by setting the defaults, then client-
        provided configuration, and finally overrides. The final property set is then
        used to configure the catalog.


        For example, a default configuration property might set the size of the
        client pool, which can be replaced with a client-specific setting. An
        override might be used to set the warehouse location, which is stored
        on the server rather than in client configuration.


        Common catalog configuration settings are documented at
        https://iceberg.apache.org/docs/latest/configuration/#catalog-properties

      summary: Get a token using an OAuth2 flow
      operationId: getToken
      description:
        Exchange credentials for a token using the OAuth2 client credentials flow or token exchange.


        This endpoint is used for three purposes -

        1. To exchange client credentials (client ID and secret) for an access token
           This uses the client credentials flow.

        2. To exchange a client token and an identity token for a more specific access token
           This uses the token exchange flow.

        3. To exchange an access token for one with the same claims and a refreshed expiration period
           This uses the token exchange flow.


        For example, a catalog client may be configured with client credentials from the OAuth2
        Authorization flow. This client would exchange its client ID and secret for an access token
        using the client credentials request with this endpoint (1). Subsequent requests would then
        use that access token.


        Some clients may also handle sessions that have additional user context. These clients would
        use the token exchange flow to exchange a user token (the "subject" token) from the session
        for a more specific access token for that user, using the catalog's access token as the
        "actor" token (2). The user ID token is the "subject" token and can be any token type
        allowed by the OAuth2 token exchange flow, including a unsecured JWT token with a sub claim.
        This request should use the catalog's bearer token in the "Authorization" header.


        Clients may also use the token exchange flow to refresh a token that is about to expire by
        sending a token exchange request (3). The request's "subject" token should be the expiring
        token. This request should use the subject token in the "Authorization" header.

        The response contains both configuration and table metadata. The configuration, if non-empty is used
        as additional configuration for the table that overrides catalog configuration. For example, this
        configuration may change the FileIO implementation to be used for the table.


        The response also contains the table's full metadata, matching the table metadata JSON file.


        The catalog configuration may contain credentials that should be used for subsequent requests for the
        table. The configuration key "token" is used to pass an access token to be used as a bearer token
        for table requests. Otherwise, a token may be passed using a RFC 8693 token type as a configuration
        key. For example, "urn:ietf:params:oauth:token-type:jwt=<JWT-token>".

        Commits have two parts, requirements and updates. Requirements are assertions that will be validated
        before attempting to make and commit changes. For example, `assert-ref-snapshot-id` will check that a
        named ref's snapshot ID has a certain value.


        Updates are changes to make to table metadata. For example, after asserting that the current main ref
        is at the expected snapshot, a commit may add a new child snapshot and set the ref to the new
        snapshot id.


        Create table transactions that are started by createTable with `stage-create` set to true are
        committed using this route. Transactions should include all changes to the table, including table
        initialization, like AddSchemaUpdate and SetCurrentSchemaUpdate. The `assert-create` requirement is
        used to ensure that the table was not created concurrently.

        The response contains both configuration and view metadata. The configuration, if non-empty is used
        as additional configuration for the view that overrides catalog configuration.


        The response also contains the view's full metadata, matching the view metadata JSON file.


        The catalog configuration may contain credentials that should be used for subsequent requests for the
        view. The configuration key "token" is used to pass an access token to be used as a bearer token
        for view requests. Otherwise, a token may be passed using a RFC 8693 token type as a configuration
        key. For example, "urn:ietf:params:oauth:token-type:jwt=<JWT-token>".

    PageToken:
      description:
        An opaque token that allows clients to make use of pagination for list APIs
        (e.g. ListTables). Clients may initiate the first paginated request by sending an empty
        query parameter `pageToken` to the server.
        
        Servers that support pagination should identify the `pageToken` parameter and return a
        `next-page-token` in the response if there are more results available.  After the initial
        request, the value of `next-page-token` from each response must be used as the `pageToken`
        parameter value for the next request. The server must return `null` value for the
        `next-page-token` in the last response.
        
        Servers that support pagination must return all results in a single response with the value
        of `next-page-token` set to `null` if the query parameter `pageToken` is not set in the
        request.
        
        Servers that do not support pagination should ignore the `pageToken` parameter and return
        all results in a single response. The `next-page-token` must be omitted from the response.
    
        Clients must interpret either `null` or missing response value of `next-page-token` as
        the end of the listing results.

        The table metadata JSON is returned in the `metadata` field. The corresponding file location of table metadata should be returned in the `metadata-location` field, unless the metadata is not yet committed. For example, a create transaction may return metadata that is staged but not committed.
        Clients can check whether metadata has changed by comparing metadata locations after the table has been created.


        The `config` map returns table-specific configuration for the table's resources, including its HTTP client and FileIO. For example, config may contain a specific FileIO implementation class for the table depending on its underlying storage.
      
      
        The following configurations should be respected by clients:
        
        ## General Configurations
        
        - `token`: Authorization bearer token to use for table requests if OAuth2 security is enabled 
        
        ## AWS Configurations
        
        The following configurations should be respected when working with tables stored in AWS S3
         - `client.region`: region to configure client for making requests to AWS
         - `s3.access-key-id`: id for for credentials that provide access to the data in S3
         - `s3.secret-access-key`: secret for credentials that provide access to data in S3 
         - `s3.session-token`: if present, this value should be used for as the session token 
         - `s3.remote-signing-enabled`: if `true` remote signing should be performed as described in the `s3-signer-open-api.yaml` specification

  securitySchemes:
    OAuth2:
      type: oauth2
      description:
        This scheme is used for OAuth2 authorization.


        For unauthorized requests, services should return an appropriate 401 or
        403 response. Implementations must not return altered success (200)
        responses when a request is unauthenticated or unauthorized.

        If a separate authorization server is used, substitute the tokenUrl with 
        the full token path of the external authorization server, and use the 
        resulting token to access the resources defined in the spec.
      flows:
        clientCredentials:
          tokenUrl: /v1/oauth/tokens
          scopes:
            catalog: Allows interacting with the Config and Catalog APIs

      type: http
