Re: help:about mysql cluster partition and parallel query

[fu zhibo]

hello,Mikael and every one
After installing Mysql NDB cluster 5.0.27 in RHEL3.0, We configurate two node groups(no replication among a node group).

I have some questions as follows:

1.It inserts data to two node group randomly? Does it scan all node groups or nodes simultaneously in full table scan and order index scan when executing a query?

2.How does mysql cluster know to fetch a row from which node when using parimary index?record node id in parimary index file? and Where is parimary index file stored?
such as a query:select * from s_pri_uni_idx where sno=2;

thanks!
