The contents of the file system is going deeper into the implementation than
I’m qualified to comment on but note that the DBDICT block is for the data
dictionary/meta data rather than the actual data.

What does the T* stand for?
Does it means the partitions?But I only set 8 partitions.

Here’s a good place to start for information on how MySQL Cluster
partitions its tables….
http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-nodes-groups.html
In general, you don’t need to specify the number of partitions, MySQL
Cluster will automatically create the correct number based on the number of
data nodes you have.

I know the default partition of mysql cluster is by primary key,but where
can I know the detail of the partition procedure?
Fox example I have 8 data node ,I set the number of partition number as 8
too,so will it partitions the whole data to 8 parts
and distributing them on 8 node uniformly?
If I don't set the partitions number explicitly,what is the default number
of the partitions number?
Thanks
