Re: 回复: 怎么不使用checkpoint

Hi 默认情况下,不调用env.enableCheckpoint,也就是不会启用checkpoint的。默认情况下的restart strategy就是NoRestart,也就是不会自动failover的。 祝好 唐云 获取 Outlook for Android From: sun <1392427...@qq.com> Sent: Friday, January 17, 2020 1:43:53 PM To: user-zh Subject: 回复:

flink内存参数

2020-01-16 文章 张江
大家好, 我正在做flink算子的性能测试,发现了以下问题。 flink加大数据量后运行时报OOM错误,但metrics中flink_taksmanager_Status_JVM_Memory_Direct_MemoryUsed,flink_taksmanager_Status_JVM_Memory_NonHeap_Used,flink_taksmanager_Status_JVM_Memory_Heap_Used一直没有波动(没有使用checkpoint,也没有网络方面的内存需求)。 想请问大家flink中这三个参数对应的内存具体是用来做什么的,OOM有可能是什么原因? 谢谢大家

原来是这样,中间的确有很多 Checkpoint 超时失败,对于这种由于 Checkpoint 失败创建的目录,Flink 本身是不会删除的,对吗? 也就是这部分状态文件,会一直存储在HDFS 上面,这种情况是否会造成 Flink Checkpoint 目录下 shared目录无限增大呢, 非常感谢你,lucas,期待你的回复。 lucas.wu 于2020年1月16日周四 下午4:50写道: > 可能是失败的checkpoint目录,可以看看程序中间是不是有失败的checkpoint > > > 原始邮件 >

Flink 1.6 版本,RocksDBStateBackend ,增量 Checkpoint 目录问题

2020-01-16 文章 LakeShen
我使用 Flink 1.6 版本,使用的增量 Checkpoint,我看官网说,默认的 Checkpoint 保留目录是1,也就是会保留一个最新完成的 Checkpoint 目录,但是在我的任务 Checkpoint 路径下面,居然有很多个 chk-xxx 目录,比如说 chk-86515,chk-37878,而且在这些目录下面,还有数据,这是什么原因呢。 对这个地方有点困惑,既然默认保留的目录是1了,为什么还有这么多 chk 目录呢。 期待你的回答
