Данные не отображаются в таблице

Question

Я попытался провести стресс-тест своего Cassandra, по какой-то причине мой инструмент Cassandra-стресс не работал на windows, поэтому в качестве обходного пути я сделал запрос POST на 100000 л oop к C*, бэкэнду был в JAVA,

Моя схема таблицы cassandra: -

CREATE TABLE Stress2.demomodel(acctID TEXT, transactionDate Date , card TEXT, amountCreditedFrom TEXT ,transactionAmount double ,balance DOUBLE, currentTime timestamp , PRIMARY KEY((acctID, transactionDate), currentTime )) WITH CLUSTERING ORDER BY (currentTime DESC);

Это мой код Looping

@Override
public DemoModel save(DemoModel demoModel) {
    int i = 0;
    try {
        for (i = 0; i < 100000; i++) {
            Thread.sleep(2L);
            demoRepository.save(demoModel);
        }
    }
    catch(Exception e) {
        throw new RuntimeException("worked till " + i);
    }
    return null;
}

Перед запуском l oop this была статистика, предоставленная инструментом Stress,

После завершения l oop, это была статистика, поскольку мы видим, что размер записываемой памяти увеличился до 13 мб

Теперь, когда я попытался грипп sh и ожидал, что некоторые данные в компактном разделе, как ни странно, было очень мало данных, вот статистика

Теперь, когда я запрашиваю таблицу, были только 3 строки, но мы можем видеть LocalWriteCount> 100000,

Вот моя модель данных для схемы,

    package com.example.connectCass.Model;

import lombok.Data;
import org.springframework.data.cassandra.core.cql.PrimaryKeyType;
import org.springframework.data.cassandra.core.mapping.Column;
import org.springframework.data.cassandra.core.mapping.PrimaryKeyColumn;
import org.springframework.data.cassandra.core.mapping.Table;
import com.datastax.driver.core.LocalDate;


import java.util.Date;


@Data
@Table
public class DemoModel {

    @PrimaryKeyColumn(name = "acctID", type = PrimaryKeyType.PARTITIONED)
    private String acctID;
    @PrimaryKeyColumn(name = "transactionDate", type = PrimaryKeyType.PARTITIONED)
    private LocalDate transactionDate;
    @PrimaryKeyColumn(name = "currentTime", type = PrimaryKeyType.CLUSTERED)
    private Date currentTime;

    @Column
    private String card;

    @Column
    private String amountCreditedFrom;

    @Column
    private double transactionAmount;

    @Column
    private double balance;

    public void setTransactionDate(){
        this.transactionDate =LocalDate.fromMillisSinceEpoch(new Date().getTime());
    }

    public void setCurrentTime(){
        this.currentTime = new Date();
    }
}

Может кто-нибудь сказать, где я иду не так? Спасибо
