Connection String Options

The connection string properties are the various options that can be used to establish a connection. This section provides a complete list of the options you can configure in the connection string for this provider. Click the links for further details.

For more information on establishing a connection, see Establishing a Connection.

Connection


PropertyDescription
BucketsSpecifies a comma-separated list of bucket names (for example, bucket1,bucket2,...). If this property is left empty, the first available bucket will be retrieved.
CustomURLSpecifies a custom S3 endpoint URL. Use for S3-compatible services or to route requests through a VPC endpoint when direct access to Amazon S3 is not available.
STSEndpointOverrideSpecifies a custom endpoint for the AWS STS (Security Token Service). This can be used when connecting to a non-standard or regional STS endpoint.
SimpleUploadLimitThis setting specifies the threshold, in bytes, above which the provider will choose to perform a multipart upload rather than uploading everything in one request.
UseLakeFormationWhen this property is set to true, AWSLakeFormation service will be used to retrieve temporary credentials, which enforce access policies against the user based on the configured IAM role. The service can be used when authenticating through OKTA, ADFS, AzureAD, PingFederate, while providing a SAML assertion.
UseVirtualHostingIf true (default), buckets will be referenced in the request using the hosted-style request: http://bucket-name.host/yourobject. If set to false, the bean will use the path-style request: http://host/bucket-name/yourobject.

AWS Authentication


PropertyDescription
AuthSchemeSpecifies the type of authentication to use when connecting to Amazon S3. If this property is left blank, the default authentication is used.

ServerSideEncryptionWhen activated, file uploads into Amazon S3 buckets will be server-side encrypted.
SSEContextA BASE64-encoded UTF-8 string holding JSON which represents a string-string (key-value) map.
SSEEnableS3BucketKeysConfiguration to use an S3 Bucket Key at the object level when encrypting data with AWS KMS. Enabling this will reduce the cost of server-side encryption by lowering calls to AWS KMS.
SSEKeyA symmetric encryption KeyManagementService key, that is used to protect the data when using ServerSideEncryption.

Keycloak Authentication

OAuth


PropertyDescription

OAuthClientIdSpecifies the client ID (also known as the consumer key) assigned to your custom OAuth application. This ID is required to identify the application to the OAuth authorization server during authentication.
OAuthClientSecretSpecifies the client secret assigned to your custom OAuth application. This confidential value is used to authenticate the application to the OAuth authorization server. (Custom OAuth applications only.).
OAuthAccessTokenSpecifies the OAuth access token used to authenticate requests to the data source. This token is issued by the authorization server after a successful OAuth exchange.
OAuthSettingsLocationSpecifies the location of the settings file where OAuth values are saved.
CallbackURLIdentifies the URL users return to after authenticating to Amazon S3 via OAuth (Custom OAuth applications only).
ScopeSpecifies the scope of the authenticating user's access to the application, to ensure they get appropriate access to data. If a custom OAuth application is needed, this is generally specified at the time the application is created.
OAuthRefreshTokenSpecifies the OAuth refresh token used to request a new access token after the original has expired.
