Description copied from interface: HostListProvider

Get current topology information for the connected database. The returned topology should be the static host list if `this` is a StaticHostListProvider. The returned topology should be fresh info returned from a topology query if `this` is a DynamicHostListProvider,

Specified by:

getCurrentTopology in interface HostListProvider

Overrides:

getCurrentTopology in class RdsHostListProvider

Parameters:

conn - the connection to use to query the database for topology information, if needed.

initialHostSpec - the host details of the initial connection.

Returns:

the topology information for the connected database.

Throws:

java.sql.SQLException - if an error occurs while attempting to acquire the database topology information.
