031/**
032 * Extends {@link IntegrationTestTimeBoundedRequestsWithRegionReplicas} for multi-gets Besides the
033 * options already talked about in IntegrationTestTimeBoundedRequestsWithRegionReplicas the addition
034 * options here are:
035 *
036 * <pre>
037 * -DIntegrationTestTimeBoundedMultiGetRequestsWithRegionReplicas.multiget_batchsize=100
038 * -DIntegrationTestTimeBoundedMultiGetRequestsWithRegionReplicas.num_regions_per_server=5
039 * </pre>
040 *
041 * The multiget_batchsize when set to 1 will issue normal GETs. The num_regions_per_server argument
042 * indirectly impacts the region size (for a given number of num_keys_per_server). That in
043 * conjunction with multiget_batchsize would have different behaviors - the batch of gets goes to
044 * the same region or to multiple regions.
