请教一下，flinkKafkaConsumer.setCommitOffsetsOnCheckpoints(true);
和kafka自己的"enable.auto.commit"=true【默认就是true,
interval=5s】，在checkpoint的时候有啥区别，假如我已经enable了chk？
看注释flinkKafkaConsumer.setCommitOffsetsOnCheckpoints()方法的注释如下：
--------------------------------------------------------
/**
* Specifies whether or not the consumer should commit offsets back to
Kafka on checkpoints.
*
* <p>This setting will only have effect if checkpointing is enabled for
the job. If
* checkpointing isn't enabled, only the "auto.commit.enable" (for 0.8)
/ "enable.auto.commit"
* (for 0.9+) property settings will be used.
*
* @return The consumer object, to allow function chaining.
*/
--------------------------------------------------------
我的理解是：意思是如果enable了checkpoint，然后设置flinkKafkaConsumer.setCommitOffsetsOnCheckpoints(true);
(貌似默认就是true)，就会采用checkpoint的interval去向kafka提交offset？
，而不采用auto.commit.enable的配置？这样理解对么？
