MySQL resolve:FailoverDataConnector failover slow

I'm using the standard com.mysql.jdbc.Driver from MySQL.  Do you know of a way I could possibly get around this issue?

Also, I get the issue that even after the initial attempt to the master has failed and the attribute-resolver is directed to the failover connector (the slave), after that attempt is successful and I've successfully logged in, the IDP still takes minutes before returning to the SP.

Thanks,
-PQ

We’re also using mysql connector string of the type below, but it still doesn’t seem like timeout values are honored.

That's up to the driver, not the IdP. We can't make their settings work. If it takes minutes, it's because the initial attempt is taking that long to fail.
