在本地环境中，测试队列(Yii2 队列扩展，queue/run 命令)模式下的并行运行

1、参考网址：https://www.shuijingwanwq.com/2021/01/22/4698/ 。queue/run 命令替换 queue/listen 命令。在本地环境中，查看 queue/run 命令队列的状态。

PS E:\wwwroot\channel-pub-api> ./yii copy-asset-queue/info --color=0
Jobs
- waiting: 20
- delayed: 0
- reserved: 0
- done: 0

2、查看 Redis 中的队列数据，cpa:queue:copy:asset.messages。数据量为 20 条。如图1

图1

3、打开2个命令行窗口，在窗口1中运行队列后，然后在窗口2中运行同样的队列。以确认当同样的队列同时运行时(集群部署时)，同一个队列作业是否会重复执行。在执行一段时间后，窗口1已经完成了2个队列作业，窗口2已经完成了3个队列作业。如图2

图2

4、在执行一段时间后，查看 Redis 中的队列数据，cpa:queue:copy:asset.messages。数据量为 15 条。如图3

图3

5、又执行一段时间后，在窗口3中运行同样的队列。查看队列状态，已经确定队列作业中等待执行的为10个，进行中的为2个，完成的为8个。如图4

图4

6、最后分别查看3个窗口中的运行情况。窗口1执行了8个队列作业。窗口2执行了12个队列作业。窗口3执行了0个队列作业，原因应该在于执行第1个队列作业时，超时失败了。

7、查看队列作业20条的操作结果。relative_path 即下载后文件的相对路径，队列作业全部执行成功。因为相对路径都存在。但是搜索应该下载的视频文件，其数量应该等于 30 。但是在下载目录中的实际视频文件数量为 32 。现在的问题是，不太清楚多出的 2 个文件是如何产生的(其中一个文件应该是早就存在的，仅多出了1个文件)。如图5

图5

8、已经确定窗口3中的队列作业超时失败，影响到了2条队列作业。虽然失败了，但是文件已经下载成功。如图6

图6

PS E:\wwwroot\channel-pub-api> ./yii source-callback-queue/info --color=0
Jobs

- delayed: 0
- reserved: 0
- done: 0

9、窗口3中的队列作业为何超时，原因应该在于本地环境的下行带宽是有限的。窗口1与窗口2已经占用了大量的带宽资源比例，导致窗口3没有带宽资源可用，因此超时。再次重复以上步骤。决定将超时时间从 600 秒调整为 1800 秒。3个窗口的队列作业全部执行成功，其中最长的执行时间为：708.338 s，难怪在之前会超时失败。因为相对路径都存在。但是搜索应该下载的视频文件，其数量应该等于 30 。但是在下载目录中的实际视频文件数量为 31 (应该在于程序内部的原因，有待于后续分析)。如图7

10、得出结论，Yii2 队列扩展 是支持并行运行的，即使在集群中同时运行，也是没有问题的。
