sequence.sample(number) → selection stream.sample(number) → array array.sample(number) → array
Select a given number of elements from a sequence with uniform random distribution. Selection is done without replacement.
If the sequence has less than the requested number of elements (i.e., calling sample(10)
on a sequence with only five elements), sample
will return the entire sequence in a random order.
Example: Select 3 random heroes.
r.table("marvel").sample(3).run(conn);
