Hi Stefan,

It is our intention that Sequoia drivers will always be backwards compatible so that you can do rolling upgrades without taking the full cluster off-line. In the last year I think that has generally worked--I can only recall one case where we broke compatibility. We don't have any big plans for changes at this point to the drivers, so it should not be too challenging to hold to this promise.

Also, we will make an effort to avoid JMX changes that break rolling upgrades, though as someone else just discovered you may need to upgrade to the latest console for things to work properly.

Cheers, Robert

Hi,

just a short question about compatibility of the Sequoia JDBC driver.
Will future versions of Sequoia work with clients that use an old
sequoia-driver (for example 2.10.5)? Or do i have to update the sequoia
jdc driver if i update sequoia?

thanx in advance

Stefan
