Build 23.0.8839

Establishing a Connection

Connecting to HarperDB

Set the Server connection property to the hostname or IP address of your HarperDB instance. Set UseSSL to secure connections with TLS/SSL.

Authenticating to HarperDB

The provider supports Basic authentication and token authentication. To authenticate, select the desired authentication method in the AuthScheme property, and set the necessary credentials described below.

Basic

Set AuthScheme to Basic. Set User and Password to a HarperDB user and password.

Token

Set AuthScheme to Token. The provider supports Token authentication through the following schemes:

  • Driver managed: Set User and Password to a HarperDB user and password. The driver handles obtaining and refreshing OperationToken and RefreshToken. Encrypted token credentials are stored at CredentialsLocation.
  • User managed: Directly specify OperationToken and RefreshToken. The driver does not attempt to refresh or reacquire token credentials after the supplied tokens expire. The supplied tokens are located at CredentialsLocation but do not persist across connections.

The provider also offers the following properties to govern token management in the Driver managed scheme:

  • OperationTokenTimeout: this governs how long the driver attempts to use a supplied OperationToken before refreshing it. It should match the setting for operation_token lifetimes in HarperDB. It defaults to the default operation_token lifetime for HarperDB.
  • RefreshTokenTimeout: this governs how long the driver attempts to use a supplied RefreshToken before refreshing it. It should match the setting for refresh_token lifetimes in HarperDB. It defaults to the default refresh_token lifetime for HarperDB.
