[GitHub] mbao opened a new issue #2270: mysql varchar(300) needed?

mbao opened a new issue #2270: mysql  varchar(300) needed?
URL: https://github.com/apache/incubator-skywalking/issues/2270
 
 
   
   ### Question
   - What do you want to know?
   
   I want to use mysql for storage. I see that create table sql use "id VARCHAR(300)", and mysql characterset is utf8mb4, so 300 * 4 > 767 and mysql returns "Index column size too large. The maximum column size is 767 bytes."
   
   I wonder if I can change 300 smaller?
