Method Detail

initializeConnection

public void initializeConnection()
                          throws QueryException

Specified by:

initializeConnection in interface Listener

Overrides:

initializeConnection in class MastersSlavesListener

Throws:

QueryException

reconnectFailedConnection

public void reconnectFailedConnection(SearchFilter searchFilter)
                               throws QueryException

search a valid connection for failed one. A Node can be a master or a replica depending on the cluster state. so search for each host until found all the failed connection. By default, search for the host not down, and recheck the down one after if not found valid connections.

Specified by:

reconnectFailedConnection in interface Listener

Overrides:

reconnectFailedConnection in class MastersSlavesListener

Throws:

QueryException - if a connection asked is not found

searchByStartName

public HostAddress searchByStartName(Protocol secondaryProtocol,
                                     List<HostAddress> loopAddress)

Aurora replica doesn't have the master endpoint but the master instance name. since the end point normally use the instance name like "instancename.some_ugly_string.region.rds.amazonaws.com", if an endpoint start with this instance name, it will be checked first.

Parameters:

secondaryProtocol - the current secondary protocol

loopAddress - list of possible hosts

Returns:

the probable master address or null if not found

checkIfTypeHaveChanged

public void checkIfTypeHaveChanged(SearchFilter searchFilter)
                            throws QueryException

Overrides:

checkIfTypeHaveChanged in class MastersSlavesListener

Throws:

QueryException
