Master/Slave topology in 4.1

[Ning Li]

Hi, 

 

I have a question about JDBC Master/Slave in 4.1.

 

In Active 4.0, each broker has its own DB, the Slave has to duplicate
the states of the Master in order to take over, how about the JDBC
Master/Slave in 4.1? Does the Slave still duplicate the states of the
Master, or it just get all the information from DB when it becomes the
Master, as the brokers share the same DB, all the state can be recovered
from the DB except some non-persistent messages will get lost.

 

 

Thanks.
