Find Recommended Number of Partitions for MDF Datastore
Determine the number of partitions you should use for your MDF datastore.
mdfds = mdfDatastore(fullfile(matlabroot,'examples','vnt','data','CANape.MF4')); N = numpartitions(mdfds);
mdfds — MDF datastore
MDF datastore object
MDF datastore, specified as an MDF datastore object.
pool — Parallel pool
parallel pool object
Parallel pool specified as a parallel pool object.
N — Number of partitions
Number of partitions, returned as a double. This number is the calculated
recommendation for the number of partitions for your MDF datastore. Use this
when partitioning your datastore with the
