Types

type Authenticator

type Authenticator struct {
	Basic BasicAuthenticator `yaml:"basic" mapstructure:",squash"`
}

Authenticator holds the authentication properties needed to connect to a Cassandra cluster

type BasicAuthenticator

type BasicAuthenticator struct {
	Username string `yaml:"username" mapstructure:"username"`
	Password string `yaml:"password" mapstructure:"password" json:"-"`
}

BasicAuthenticator holds the username and password for a password authenticator for a Cassandra cluster

}

Configuration describes the configuration properties needed to connect to a Cassandra cluster

func (*Configuration) ApplyDefaults

func (c *Configuration) ApplyDefaults(source *Configuration)

ApplyDefaults copies settings from source unless its own value is non-zero.

func (*Configuration) NewCluster

func (c *Configuration) NewCluster(logger *zap.Logger) (*gocql.ClusterConfig, error)

NewCluster creates a new gocql cluster from the configuration

func (*Configuration) NewSession

func (c *Configuration) NewSession(logger *zap.Logger) (cassandra.Session, error)

NewSession creates a new Cassandra session

func (*Configuration) String

func (c *Configuration) String() string

type SessionBuilder

type SessionBuilder interface {
	NewSession(logger *zap.Logger) (cassandra.Session, error)
}

SessionBuilder creates new cassandra.Session
