Flink CDC任务全量跑完后 jvm heap 内存占用一直在增加不知道为啥？

Flink CDC任务全量跑完后 jvm heap 内存占用一直在增加不知道为啥？已经从占用1.6G增加到2.2G了，就是我有两个任务都是单表同步全量+增量全量同步完毕后jvm heap 占用1.6G 然后过了三分钟内存占用飙到了 2.2G 这期间并没有增量任务

Flink CDC我的任务初始化过程中感觉会重复的全量读取某些表的数据，这可能是什么情况呢？

大佬们，Flink CDC我的任务初始化过程中感觉会重复的全量读取某些表的数据，比如我同步的几张表加起来数据量也就5000万，现在跑了6000万数据，还没有跑完，并且有的表还没有同步，数据是0，这可能是什么情况呢？

Flink CDC中当前是启动任务全量数据可以同步，增量数据不同步怎么排查？

Flink CDC中，我是flink1.17.1+mysql cdc2.4.0+mysql5.7（source端），当前是启动任务全量数据可以同步，增量数据不同步，checkpoint开启了，也没见什么异常信息。怎么排查？我这边使用的Dinky，通过SQL的方式做的，如下是SQL配置部分

Flink CDC中这个动态加表，昨天新启任务，新加的表它不读全量增量它也不读了，什么原因？

Flink CDC中这个动态加表，昨天新启任务，新加的表从全量阶段读，我今天把任务停了，重新启动，它这回不读全量了，但是新加的那几张表，增量它也不读了，什么原因？我想知道的一点是，新加的表，是一定会先做全量快照吗？因为我看到jm日志还是在做 split，切片太多 JM给我干OOM了。而且新加的表的切...

Flink CDC中停任务新加表，只能从全量阶段开始嘛，能不能跳过全量，直接进增量呀？

Flink CDC中停任务新加表，只能从全量阶段开始嘛，能不能跳过全量，直接进增量呀？我重启任务 start mode用的latest-offset，它也是从全量阶段开始，scan.incremental.snapshot.enabled把这个参数改成false能行不？
