排行榜优化之-写读数据不一致问题排查

1️⃣、背景

在营销业务需求中，每个活动的参与用户拥有活动对应的资产，活动期间和活动结束后，在小程序页面都需要展示当前活动下的参与用户资产排行。

排序的逻辑是：用户的总资产+最先参与时间，总资产相同的情况下，最先参与活动的排前面。在活动期间，总资产会随着用户的动作动态变化。

界面展示如下:

2️⃣、实现方式

直接从数据库中，通过sql查询排序获取。这种方式实现起来简单，但是也有缺点：每次都从数据库中获取，单表数据量大的时候，查询，排序并不高效。
获取排行榜接口从redis中取前N排名，在资产管理类中新增事件监听当前用户的资产变化，及时更新到redis中。此种方案涉及到技术难点如下：
1. 以什么样的数据结构存到redis中。
  1. redis的基于分数的有序集合,命令格式：(ZADD KEY_NAME SCORE1 VALUE1.. SCOREN VALUEN)，可以看到此种数据结构是根据score的值来排序的，而我们的排序条件是个组合条件，如果用这种结构，需要一个算法把组合条件（total+time）的转成一个score值，并且这个value，我们需要存入当前参与用户对象的一些信息。
  2. 在翻看redisson 文档时发现reddisson支持sortset这样一种结构（https://github.com/redisson/redisson/wiki/7.-distributed-collections/#74-sortedset），背后的存入redis的其实是list，排序的方式可以自定义，这个list由reddssion维护，取出来就是已经排好序的列表，所以我选择了这种数据结构。
2. 用户资产变化时怎么保持排名的正确性。用户资产变化存在以下几种情况。
  1. 用户资产变化，排名不变。并在TopN中。
  2. 用户资产变化，排名变更，名次还在TopN内.
  3. 用户资产变更，之前不在TopN，本次变更在TopN中。
  4. 用户资产变更，排名跌出TopN。缓存变更，当前用户剔除缓存，新用户加入topN。

3️⃣、发现问题

从实现方式可以知道，要通过redis来存当前活动的排行榜数据，需要逻辑来维护这份数据，因为用户的资产在活动期间是动态变化的。在代码中，当用户资产变化的时候，通过一个应用内异步事件拿当前变化的数据更新redis中的数据。实现代码如下：

    public void assetsAdd(Long activityId, Long activityJoinId, ActivityAssetsLogEnums.AssetsLogType type, Integer assetsValue, AssetsCallback callback) throws BusinessException {
        //前置业务
        AssetsCallbackResult callbackResult = callback.callback();
        //资产添加成功
        if (activityJoinDao.assetsIncr(activityJoinId,assetsValue)) {
            activityAssetsLogDao.addLog(activityId,activityJoinId,type.getCode(),assetsValue,callbackResult.getRemark(),callbackResult.getBizId());
			//推送资产变更事件（异步）
            eventBusPublisher.publishAsync(new ActivityJoinAssertChangeEvent(activityId,activityJoinId, ActivityJoinEnums.AssertChangeType.ASSETS_ADD,assetsValue));
        } else {
            throw BusinessExceptionFactory.create(BizErrorCodeEnum.ERROR_CODE_ACTIVITY_ASSETS_COMMON,"参与人不存在");
        }
    }
	//资产变更事件监听
    public void activityJoinAssertChange2Redis(ActivityJoinAssertChangeEvent event) {
        if (event.getAssertChangeType().equals(ActivityJoinEnums.AssertChangeType.ASSETS_CONSUME)) {
            return;
        }
        String key = String.format(USER_JOIN_ACTIVITY_ASSETS_RANK.getKey(), event.getActivityId());
        RSortedSet<ActivityAssetsRankData> dataRSortedSet = redissonHelper.getRedissonClient().getSortedSet(key);
        //数据如果是空的不用管，在调用资产排行接口的时候会初始化
        if (dataRSortedSet.isEmpty()) {
            return;
        }
        List<ActivityAssetsRankData> activityAssetsRankDataList = dataRSortedSet.readAll().stream().collect(Collectors.toList());
		/******读取当前用户的资产********/
        MmsActivityJoinEntity mmsActivityJoinEntity = activityJoinEntityMapper.selectByID(event.getActivityJoinId());
        Optional<ActivityAssetsRankData> activityAssetsRankDataOptional = activityAssetsRankDataList.stream().filter(data -> data.getId().equals(event.getActivityJoinId())).findFirst();
        ActivityAssetsRankData activityAssetsRankData = new ActivityAssetsRankData();
        if (activityAssetsRankDataOptional.isPresent()) {
            activityAssetsRankData = activityAssetsRankDataOptional.get();
            activityAssetsRankDataList.remove(activityAssetsRankData);
        }
        BeanUtils.copyProperties(mmsActivityJoinEntity, activityAssetsRankData);
        activityAssetsRankDataList.add(activityAssetsRankData);
        if (activityAssetsRankDataList.size() > rankConst) {
            activityAssetsRankDataList.sort(activityAssetsRankData);
            activityAssetsRankDataList = activityAssetsRankDataList.subList(0, rankConst);
            if (activityAssetsRankDataList.indexOf(activityAssetsRankData) != -1) {
                dataRSortedSet.clear();
                dataRSortedSet.addAll(activityAssetsRankDataList);
            }
        } else {
            dataRSortedSet.clear();
            dataRSortedSet.addAll(activityAssetsRankDataList);
        }
    }

当用户资产变更是，发布异步事件，异步更新redis中的排行数据。这个逻辑看上去很美好，但是实际测试下来发现当用资产由10变成20时，异步逻辑中有几率读到的资产还是10？这样就导致缓存中数据不正确。

5️⃣、分析问题

出现这种问题需要从一下几个方面考虑：

主从同步延时问题，当更新了数据，马上查询，有可能更新了主库，而查询走从库，导致查询数据不一致。
mybatis缓存问题，mybatis在查询条件一致的情况下，会优先从一级缓存中读取数据。
事物原因导致数据读取不一致。

6️⃣、排查问题

既然有了怀疑的对象，我们就开始一一排查。

主从同步

从配置中心看，数据库主从都是配的一个地址，并且指向的是ecs实例，因此可能不是主从同步问题导致。

mybatis缓存问题

mybatis配置中，有是否开启缓存等配置，有全局的也有局部的，因此我在xml实现了这么一个查询配置（useCache="false" flushCache="true"）不使用缓存，并且刷新缓存。

  <select id="selectByID"  resultMap="cn.mwee.msh.mms.data.mapper.MmsActivityJoinEntityMapper.BaseResultMap" useCache="false" flushCache="true">
    select * from mms_activity_join where id=#{activityJoinId}
  </select>

测试下来还是存在读取数据不一致。

事物

要分析是不是事物原因，我们要借助日志，因此首先需要打开相关的日志配置如下：

/**打开数据库操作日志*/ 
<Logger name="com.alibaba.druid" level="DEBUG" additivity="false">
        <AppenderRef ref="STDOUT"/>
        <AppenderRef ref="JAR_LOG_FILE"/>
    </Logger>

    <Logger name="org.mybatis.spring" level="DEBUG" additivity="false">
        <AppenderRef ref="STDOUT"/>
        <AppenderRef ref="JAR_LOG_FILE"/>
    </Logger>

    <Logger name="tk.mybatis" level="DEBUG" additivity="false">
        <AppenderRef ref="STDOUT"/>
        <AppenderRef ref="JAR_LOG_FILE"/>
    </Logger>

    <Logger name="org.apache.ibatis" level="DEBUG" additivity="false">
        <AppenderRef ref="STDOUT"/>
        <AppenderRef ref="JAR_LOG_FILE"/>
    </Logger>
/**关闭缓存同步日志*/
    <Logger name="cn.mwee.base_common.cache.CachePoolHelper" level="INFO" additivity="false" >
    </Logger>

- 第一步：代码中加入日志打印，

1. 1. 在资产变更的方法中通过mapper查询当前用户的资产数据，并打印日志。
  2. 在事件监听方法中通过mapper查询当前用户资产数据，并打印日志。

从日志中我们可以看到，

🔴的记录，在资产变更的逻辑中读取到的用资产是40，而在异步事件监听中读到了30。

🔵看出从抽奖-资产变更-发奖，都在一个事物中。

⚫️异步监听中创建了一个新的事物，发奖事物提交在异步监听事物后面。

所以极有可能是mysql的事物隔离导致数据读取不一致的问题，然后查看下当前数据库的事物隔离级别：

show variables like '%isolation%'，当前数据库的事物隔离级别为：READ-COMMITTED，表示B事物能读到A事物的提交后的数据。也就能解释为什么异步监听中读不到最新的数据，因为异步监听触发后，资产变更事务未提交。

7️⃣、解决问题

从上面我们得知问题的原因，由此可以知道要解决当前问题有几种方式：

在资产变更事务中，查询当前用的资产数据作为参数，传到异步事件中。
更新用户资产的逻辑，开启一个新的事物，完成更新并提交。
更新用户资产的逻辑事物配置为PROPAGATION_NOT_SUPPORTED，即当前逻辑不使用事物提交。

分析下来：个人觉得方式1能解决当前问题，方式2能解决资产变更逻辑中读取不一致的问题。因此采用方式2来解决。

    public boolean assetsIncr(Long id,Integer assetsValue) {
        DefaultTransactionDefinition defaultTransactionDefinition= new DefaultTransactionDefinition();
        defaultTransactionDefinition.setPropagationBehavior(PROPAGATION_REQUIRES_NEW);
        TransactionStatus status =  platformTransactionManager.getTransaction(defaultTransactionDefinition);
        boolean success=false;
        try {
            success= mapper.assetsIncr(id, assetsValue) > 0;
            platformTransactionManager.commit(status);
        } catch (Exception e) {
            platformTransactionManager.rollback(status);
            throw e;
        }
        return success;
    }
