I’m trying to horizontal sharding in mysql. I installed MySQL cluster and every thing work well. But i don’t know how to horizontal sharding my database.
Detail:
I have 2 data node: Node1 and Node2.
I created database Test with one table T1(key(int), field1..).
Now I want to 50% record of T1 save on Node1( odd value of key) , and 50% another on Node2 ( even value of key).
