   Actually, we don't expect 1222709 milliseconds for meta data loading for 7169 tables.
   Time cost for one query: 1222709/7169 = 170ms
   IMO, this kind of query usually cost 1~2ms or even less.
   
   There're two possibilities:
   1. There's bug in ShardingSphere. I'll double check.
   2. You machine is too slow. Please provide your hardware environment. And check is there any other service running on this machine.
