Alternative to Maxscale...
...there's always good old MySQL Proxy (it never went GA, but I've used it) or the newer MySQL Router, both of which don't appear to have any sort of BSL-style licence tied to them and both can be used with MariaDB server installs as the backends.
MySQL Proxy was a bit too simplistic perhaps (very simple round robin by default, requiring some Lua-based work to balance based on load/connections) and I certainly didn't like the number of g_assert() calls in the production source code (262 at the last count), but it seemed to do its job OK.
Biting the hand that feeds IT
