Types

type OpenGaussInstance

type OpenGaussInstance struct {
	*dtstruct.Instance
	*SyncInfo
}

OpenGaussInstance hold opengauss instance basic info and sync info

func NewInstance

func NewInstance() *OpenGaussInstance

NewInstance creates a new, empty instance

func (*OpenGaussInstance) GetDatabaseType

func (o *OpenGaussInstance) GetDatabaseType() string

func (*OpenGaussInstance) GetHandler

func (o *OpenGaussInstance) GetHandler() dtstruct.InstanceAdaptor

func (*OpenGaussInstance) GetHostname

func (o *OpenGaussInstance) GetHostname() string

func (*OpenGaussInstance) GetInstance

func (o *OpenGaussInstance) GetInstance() *dtstruct.Instance

func (*OpenGaussInstance) GetPort

func (o *OpenGaussInstance) GetPort() int

func (*OpenGaussInstance) HumanReadableDescription

func (o *OpenGaussInstance) HumanReadableDescription() string

func (*OpenGaussInstance) IsReplica

func (o *OpenGaussInstance) IsReplica() bool

func (*OpenGaussInstance) IsReplicaServer

func (o *OpenGaussInstance) IsReplicaServer() bool

IsReplicaServer no replica server in opengauss like binlog server in mysql

func (*OpenGaussInstance) Less

func (o *OpenGaussInstance) Less(otherInst dtstruct.InstanceAdaptor, dataCenter string) bool

Less use replay location and promotion rule and physical location

func (*OpenGaussInstance) MarshalJSON

func (o *OpenGaussInstance) MarshalJSON() ([]byte, error)

func (*OpenGaussInstance) ReplicaRunning

func (o *OpenGaussInstance) ReplicaRunning() bool

ReplicaRunning instance should be replica and with valid last check and with valid upstream key

func (*OpenGaussInstance) SetFlavorName

func (o *OpenGaussInstance) SetFlavorName()

func (*OpenGaussInstance) SetHstPrtAndClusterName

func (o *OpenGaussInstance) SetHstPrtAndClusterName(hostname string, port int, upstreamHostname string, upstreamPort int, clusterName string)

func (*OpenGaussInstance) SetInstance

func (o *OpenGaussInstance) SetInstance(instance *dtstruct.Instance)

func (*OpenGaussInstance) SetPromotionRule

func (o *OpenGaussInstance) SetPromotionRule(rule dtstruct.CandidatePromotionRule)

type SyncInfo

type SyncInfo struct {
	SenderSentLocation       string
