// in this case we want to load a 10% sampling set of the data
data:
LOAD ….<your fields>…
FROM <your QVD file>
WHERE ceil(rand() * 100) <= 10;  // or: rand() <= 0.1

// SAMPLE n LOAD is much faster but allocates the memory of the full data set during the LOAD
// Where rand() <= n allocates only the memory of the smaller result set which could be crucial with Big Data..
