   @songxu Hi, recently i am fixing this problem, and this issue occurrs to me. 
ShardingSphere needs a copy of metadata info to help parsing your SQLs, and 
checks the metadata consistancy of all the sharding tables. But there is a 
switch named `check.table.metadata.enabled` to decide to check it or not. If 
you don't want to cost too much time when startup, you can config this 
property. More details, please refer to our document. Thanks.
