func (CustomAwsCredentialsProvider) GetAwsCredentialsProvider ¶

func (c CustomAwsCredentialsProvider) GetAwsCredentialsProvider(hostInfo host_info_util.HostInfo, props map[string]string) (aws.CredentialsProvider, error)

func (*CustomConnectionProvider) AcceptsStrategy ¶

func (c *CustomConnectionProvider) AcceptsStrategy(strategy string) bool

Adds criteria for which host selection strategies are supported. This implementation returns true if strategy is part of acceptedStrategies.

func (*CustomConnectionProvider) AcceptsUrl ¶

func (c *CustomConnectionProvider) AcceptsUrl(hostInfo host_info_util.HostInfo, props map[string]string) bool

Adds criteria for which hosts and properties are supported by this connection provider. This implementation accepts any values, meaning all connections will connect through this connection provider.

func (*CustomConnectionProvider) Connect ¶

func (c *CustomConnectionProvider) Connect(hostInfo *host_info_util.HostInfo, props map[string]string, pluginService driver_infrastructure.PluginService) (driver.Conn, error)

Creates a connection with the database. This implementation passes a dsn to its targetDriver to connect.

func (*CustomConnectionProvider) GetHostInfoByStrategy ¶

func (c *CustomConnectionProvider) GetHostInfoByStrategy(hosts []*host_info_util.HostInfo, role host_info_util.HostRole, strategy string, props map[string]string) (*host_info_util.HostInfo, error)

Selects a host from hosts using the provided strategy. This implementation passes the task to a HostSelector.

func (*CustomConnectionProvider) GetHostSelectorStrategy ¶

func (c *CustomConnectionProvider) GetHostSelectorStrategy(strategy string) (driver_infrastructure.HostSelector, error)

Returns a HostSelector that will select a preferred host from a list of hosts. This implementation will always return the corresponding HostSelector to strategy from acceptedStrategies.

func (*FirstHostSelector) GetHost ¶

func (h *FirstHostSelector) GetHost(hosts []*host_info_util.HostInfo, role host_info_util.HostRole, props map[string]string) (*host_info_util.HostInfo, error)

Implements a strategy to select a host from a list of hosts. This implementation returns the first host in the list regardless of role or props.
