Functions

func CanReplicateFrom

func CanReplicateFrom(first dtstruct.InstanceAdaptor, other dtstruct.InstanceAdaptor) (bool, error)

CanReplicateFrom check if first instance can practically replicate from other instance

func DelayReplication

func DelayReplication(instanceKey *dtstruct.InstanceKey, seconds int) error

DelayReplication set the replication delay given seconds on the given instance

func GetReplicationAnalysis

func GetReplicationAnalysis(dbt string, clusterName, clusterId string, hints *dtstruct.ReplicationAnalysisHints) ([]dtstruct.ReplicationAnalysis, error)

GetReplicationAnalysis will check for replication problems (dead master; unreachable master; etc)

func ResetReplication

func ResetReplication(instanceKey *dtstruct.InstanceKey) (dtstruct.InstanceAdaptor, error)

ResetReplication will reset a replica's replication

func RestartReplication

func RestartReplication(instanceKey *dtstruct.InstanceKey) (detail interface{}, err error)

RestartReplication stop & start replication on the given instance

func SetReadOnly

func SetReadOnly(instanceKey *dtstruct.InstanceKey, readOnly bool) (dtstruct.InstanceAdaptor, error)

SetReadOnly set or clear the instance's read only setting

func SetSemiSyncOnDownstream

func SetSemiSyncOnDownstream(instanceKey *dtstruct.InstanceKey, enable bool) (dtstruct.InstanceAdaptor, error)

SetSemiSyncOnDownstream enable or disable semi sync replication on the downstream instance

func SetSemiSyncOnUpstream

func SetSemiSyncOnUpstream(instanceKey *dtstruct.InstanceKey, enable bool) (dtstruct.InstanceAdaptor, error)

SetSemiSyncOnUpstream enable or disable semi sync replication on the upstream instance

func StartReplication

func StartReplication(instanceKey *dtstruct.InstanceKey) (interface{}, error)

StartReplication start replication on the given instance.

func StopReplication

func StopReplication(instanceKey *dtstruct.InstanceKey) (interface{}, error)
