All Implemented Interfaces:

OperationMixRunner

public class SamplingOperationMixRunner
extends AbstractOperationMixRunner

An operation mix runner that runs a sample of the operations in the mix respecting whether random order has been selected.

The sample is configurable and may be larger/smaller than the size of the mixes to be run, optionally the sample may include repeats of operations.

In the case where random order is disabled and the sample size is smaller than the mix size only the first N operations (where N is the sample size) will be run and the remaining operations will never be run.

In the case where the desired sample size is larger than the mix size but repeats are not allowed then the actual sample size will be the same as the mix size and every operation will be run precisely once.
