使用flink cdc on yarn运行，先全量后增量的方式，这种情况咱们有什么好的建议吗？

使用flink cdc on yarn运行，先全量后增量的方式，采集数据到starrocks，碰到数据量太大的情况，比如5000万以上，就可能会遇到采集超时任务失败的情况，数据一致性得不到保障，这种情况咱们有什么好的建议吗？

Flink CDC中sqlserver同步过程中，先全量然后增量，会出现直接暂停的现象，什么原因？

"Flink CDC中sqlserver同步过程中，先全量然后增量，会出现直接暂停的现象，我看代码似乎是触发了增量同步，然而实际上表并没有任何数据改动，如果数据库其他cdc表没有变动不会出现这个问题，实际上全量没有完全，在方法里面出不来了，什么原因？版本2.4.1。"
