Types

type ConnectionConfig

type ConnectionConfig struct {
	// Broker Address. Comma-separated list of "host:port" expected
	Address     string      `mapstructure:"address"`
	StartOffset StartOffset `mapstructure:"start_offset"`
}

func (*ConnectionConfig) Validate

type ConnectionsConfig

type ConnectionsConfig map[string]*ConnectionConfig

func (*ConnectionsConfig) Validate

type Container

type Container struct {
	// contains filtered or unexported fields
}

Container is a simple container for holding named kafka connections.

	topics []string,
) (*kafka.Reader, error)
