测试了一下,是支持的。
只是flink1.14.4删除了blink相关的包,所以maven编译时会报错,直接使用下面引用运行不会有问题。
<dependency>
<groupId>io.github.jeff-zou</groupId>
<artifactId>flink-connector-redis</artifactId>
<version>1.0.11</version>
</dependency>
如果要自行编译的话请删除pom文件里的blink相关包引用。

请问你有过flink 大窗口checkpoint 超时问题经历吗? |
有的,中间状态数据量太大了就会出现,你用的是flink哪个版本

我用1.14.4和1.15.0都会有这个问题,超时达到次数就把taskmanager搞挂了,你是如何解决这个问题的呢? |
是不是试了增量checkpoint也没用? 如果没试过可以试一下,之前我的状态非常大用增量也没用,后面是调整业务实现方式,绕开了checkpoint, 大致思路是将任务拆分成两个,第一个任务先预处理,第二个任务做聚合计算时只需要对简单数据进行checkpoint. 可以加我v聊 zilong954224 |
对的,增量checkpoint也没用,我这边是因为窗口开了一个小时,数据来源频率是每10分钟会产生20多万数据 |
数据量不大呀,单条数据有多大,是其它问题吧,平常checkpoint能成功不?
