Method Detail

createClient

public static Client createClient()

Create a Client with no connections and all default options. Authentication will use a blank username and password.

Returns:

Newly constructed Client

createClient

public static Client createClient(ClientConfig config)

Recommended method for creating a Client.

Using a ClientConfig object ensures that a client application is isolated from changes to the configuration options. Authentication credentials are provided via the configuration object.

Parameters:

config - A ClientConfig object

Returns:

A configured Client

createClient

public static Client2 createClient(Client2Config config)

Create a "version 2" client, Client2.

This call takes a Client2Config argument, which distinguishes it from createClient(ClientConfig).

All client options, including authentication information, are provided via the Client2Config object.

Parameters:

config - A Client2Config object

Returns:

A configured Client2

preserveResources

public static void preserveResources()

Internally used by the VoltDB server during initialization.

This method is intended to ensure that the resources needed to create clients are always initialized and won't be released when the active client count goes to zero.
