Enhancement to mysql odbc to improve Aurora failover recovery

When an Aurora MySql cluster fails over it can take 30 seconds or more before the DNS is updated to allow the client to reconnect to the writer. Aurora MySql has an internal function to query the current topology. By querying the internal topology we can use this to reduce the failover time to around 5 seconds. We (Amazon) would like to propose an enhancement to the ODBC driver that would leverage this feature. What is the best way to proceed to get this into the ODBC driver ?

Regards,

Dave Cramer
