??????Too many sub tables lead to slow start

Set check.table.metadata.enabled: false to start slowly


I have nearly 3000 watches



As shown in the attachment code location


Very time-consuming

Hi


The configuration option `check.table.metadata.enabled` which decides to check 
metadata of each table or not
can affect the speed of start-up.

Hello
I use mysql5 database
Sharding version: 4.0.0-rc2
As there are about 2000 tables, the program starts slowly. Is there any way to 
solve this problem?
