Types

type ConnectionProducer

type ConnectionProducer interface {
	Close() error
	Initialize(context.Context, map[string]interface{}, bool) error
	Connection(context.Context) (interface{}, error)

	sync.Locker
}

ConnectionProducer can be used as an embeded interface in the Database definition. It implements the methods dealing with individual database connections and is used in all the builtin database types.

type SQLConnectionProducer

type SQLConnectionProducer struct {
	ConnectionURL            string      `json:"connection_url" structs:"connection_url" mapstructure:"connection_url"`
	MaxOpenConnections       int         `json:"max_open_connections" structs:"max_open_connections" mapstructure:"max_open_connections"`
	MaxIdleConnections       int         `json:"max_idle_connections" structs:"max_idle_connections" mapstructure:"max_idle_connections"`
	MaxConnectionLifetimeRaw interface{} `json:"max_connection_lifetime" structs:"max_connection_lifetime" mapstructure:"max_connection_lifetime"`

	Type string

	Initialized bool

	sync.Mutex
	// contains filtered or unexported fields
}

SQLConnectionProducer implements ConnectionProducer and provides a generic producer for most sql databases

func (*SQLConnectionProducer) Close

func (c *SQLConnectionProducer) Close() error

Close attempts to close the connection

func (*SQLConnectionProducer) Connection

func (c *SQLConnectionProducer) Connection(ctx context.Context) (interface{}, error)

func (*SQLConnectionProducer) Initialize

func (c *SQLConnectionProducer) Initialize(ctx context.Context, conf map[string]interface{}, verifyConnection bool) error
