Hi!
Yes, internally the primary key can be used
to locate the primary partition (when using
default partitioning). This is used to decide
where the transaction coordinator should run,
the primary key of the first row (if available)
is used as "hint" when starting the transaction.
For user defined partitioning the partitioning
function decides.
This is transparent from SQL, but can be controlled
in the low level API (Ndb API).
