� For small installation Aurora is not a good fit, PXC was working better� As workload scale and make sense to use larger boxes Aurora had
shown better results, scaling as expected.� Aurora has still some issues (known):
� Hard limit to 16k connections� When using hotspot it is easy to hit the 158 error problem (no is not the
Full text error)� I am sure that I hit some connector issue here and there, exploring

I like to provide to my customer alternatives, Aurora is one but …
