Functions

func GetMembers 

func GetMembers(etcdClient *clientv3.Client) ([]*pdpb.Member, error)

GetMembers return a slice of Members.

func LogPDInfo 

func LogPDInfo()

LogPDInfo prints the PD version information.

func NewTestServer 

func NewTestServer(c *check.C) (*Config, *Server, CleanupFunc)

NewTestServer creates a pd server for testing.

func ParseUrls 

func ParseUrls(s string) ([]url.URL, error)

ParseUrls parse a string into multiple urls. Export for api.

func PrepareJoinCluster 

func PrepareJoinCluster(cfg *Config) error

PrepareJoinCluster sends MemberAdd command to PD cluster, and returns the initial configuration of the PD cluster.

TL;TR: The join functionality is safe. With data, join does nothing, w/o data 

and it is not a member of cluster, join does MemberAdd, it returns an
error if PD tries to join itself, missing data or join a duplicated PD.

Etcd automatically re-joins the cluster if there is a data directory. So first it checks if there is a data directory or not. If there is, it returns an empty string (etcd will get the correct configurations from the data directory.)

If there is no data directory, there are following cases:

  • A new PD joins an existing cluster. What join does: MemberAdd, MemberList, then generate initial-cluster.

  • A failed PD re-joins the previous cluster. What join does: return an error. (etcd reports: raft log corrupted, truncated, or lost?)

  • A deleted PD joins to previous cluster. What join does: MemberAdd, MemberList, then generate initial-cluster. (it is not in the member list and there is no data, so we can treat it as a new PD.)

If there is a data directory, there are following special cases:

  • A failed PD tries to join the previous cluster but it has been deleted during its downtime. What join does: return "" (etcd will connect to other peers and find that the PD itself has been removed.)

  • A deleted PD joins the previous cluster. What join does: return "" (as etcd will read data directory and find that the PD itself has been removed, so an empty string is fine.)

func PrintPDInfo 

func PrintPDInfo()

PrintPDInfo prints the PD version information without log info.

func StartMonitor 

func StartMonitor(now func() time.Time, systimeErrHandler func())
