• repeated common.Peer peers = 3

• required uint64 epoch = 4

• optional curve.mds.heartbeat.ConfigChangeType type = 5

• optional common.Peer configchangeItem = 6

  configchangeItem is the target node for TRANSFER_LEADER: the target peer; for ADD_PEER: the peer to add; for REMOVE_PEER: the peer to delete; for CHANGE_PEER: the peer to add;

• optional common.Peer oldPeer = 7

  oldPeer, This will only be assigned when ConfigChangeType=CHANGE_PEER, Indicates the peer to be deleted. The metaserver receives CHANGE_PEER and put together a new conf based on peers, configchangeItem, and oldPeer

• required uint64 memoryCopySetMinRequireByte = 5

  Minimum memory requirement for copy on this metaserver

• required uint64 memoryUsedByte = 6

  The amount of memory used by the current process of this metaserver
