Detailed Description

template<concepts::Rdd R>
requires std::invocable<std::function<bool(int)>, utils::RddElementType<R>>&& std::is_convertible_v< std::invoke_result_t<std::function<bool(int)>, utils::RddElementType<R>>, bool>
class cpark::SampleRdd< R >

An Rdd holding the sampled data from an old rdd by a specific sample fraction

Template Parameters

R	Type of the old Rdd. The type of the old Rdd R's elements should be able to invoke random boolean function, the invoke result must be in boolean, and the element type shouldn't change after sampling.

Examples

filter_even.cpp.
