Method of rolling restart based on esgyndb database

A method of rolling restart based on EsgynDB Database, comprising the following steps:

• S1:
• the ZooKeeper in the system is used as the coordinator to update the MXOSRVR state required to be restarted in the instruction according to the framework of EsgynDB Database;
• S2:
• when MXOSRVR discovers that its state has been updated to “to be restarted”, it will add a piece of string information to the next information returned to Driver to inform the client that MXOSRVR is in the state of “to be restarted”;
• S3:
• the client Driver will keep the context information of the current connection and parse the protocol in each interaction with MXOSRVR, when Driver knows that MXOSRVR requires to be restarted through parsing the newly added information by string, the client will reconnect according to the security point state of the whole business state.
