多源复制中特定从站的主站数量 MySQL？
Number of masters for particular slave in multi source Replication MySQL?
Mysql 推出了一项新功能，即单个从属服务器有多个主服务器，其中可以在每个单独的主服务器的名为通道的标志的帮助下处理复制。
我想知道：
What's the max number of master a slave can have ?
Or
max number of channels a slave can have ?
谢谢
in MySQL 5.7, the maximum number of channels that can be added to one slave in a multi-source replication topology is 256.
