Sequential scan method for NDB storage engine

[<yotaro.nakayama]

Hi,

I have a question about the execution of the sequential scan in NDB
storage engine.

Suppose that the configuration of NDB is defined as four data nodes and
two replicas.

When a sequential scan by a select with non-key column is performed on a
SQL node,
which is the execution method for the sequential scan for each data
node, parallel execution 
or sequential execution?
