JIN SUN commented on FLINK-10205: --------------------------------- Great Stephan, i actually has the same idea, for the batch failover, there are a bunch of things we need to consider and discuss. I can prepare a FLIP. > Batch Job: InputSplit Fault tolerant for DataSourceTask > ------------------------------------------------------- > > Key: FLINK-10205 > URL: https://issues.apache.org/jira/browse/FLINK-10205 > Project: Flink > Issue Type: Sub-task > Components: JobManager > Reporter: JIN SUN > Assignee: JIN SUN > Priority: Major > Original Estimate: 168h > Remaining Estimate: 168h > > Today DataSource Task pull InputSplits from JobManager to achieve better > performance, however, when a DataSourceTask failed and rerun, it will not get > the same splits as its previous version. this will introduce inconsistent > result or even data corruption. > Furthermore, if there are two executions run at the same time (in batch > scenario), this two executions should process same splits. > we need to fix the issue to make the inputs of a DataSourceTask > deterministic. The propose is save all splits into ExecutionVertex and > DataSourceTask will pull split from there. > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
