Same here, I support Python as the language choice. > That said, it has a serious problem with its global interpreter lock > for threading.

You don't need to worry about threads aith non-blocking I/O. That's actually one of the main reasons to use non-blocking I/O, so you don't need one thread/connection. :) This means you need to store a little more state if you have multiple non-blocking connections, but all very doable. > >2) Would you be unable to use a client written in Python 3?

I would love to be more forward facing and use Python 3, but it's just not quite there yet with the distros. > >3) How important a factor is performance in our language choice and > >design of the client? > > Well, this will depend on who is using the client and for what > purposes.

Yeah, we can develope separate tools for bulk loading based on the replication API if needed. With Python we also have the option or writing a module in C/C++ and loading that in instead too for performance gains (like what bzr has done with some parts). -Eric _______________________________________________ Mailing list: https://launchpad.net/~drizzle-discuss Post to : [email protected] Unsubscribe : https://launchpad.net/~drizzle-discuss More help : https://help.launchpad.net/ListHelp
