SArray. sample(fraction, seed=None, exact=False)¶
Create an SArray which contains a subsample of the current SArray.
| Parameters: | fraction : float Fraction of the rows to fetch. Must be between 0 and 1. if exact is False (default), the number of rows returned is approximately the fraction times the number of rows. seed : int, optional The random seed for the random number generator. exact: bool, optional Defaults to False. If exact=True, an exact fraction is returned, but at a performance penalty. |
