.Flink cdc任务在同步过程中新增同步表后选择全量初始化历史数据，初始化什么时候开始？

1.Flink cdc任务在同步过程中新增同步表后选择全量初始化历史数据，如果十几个小时才能初始化完成，无锁算法开始增量的时候是从十几个小时前的binlog位点增量还是从当前时间位点增量。（如果是从十几个小时前的binlog位点衔接增量，如果binlog已经归档了，就会报错文件找不到）新增大表初...

Flink CDC 里初始化这么大，用flink cdc 来会不会有点慢呢？

flink cdc在全量快照初始化阶段如果任务异常自动从ck restore后会这样吗？

flink cdc在全量快照初始化阶段如果任务异常自动从ck restore后会从上次binlog断点续传么？

Flink cdc快照初始化中经常出现这样的异常，这个要配置哪些参数？

Flink cdc快照初始化中经常出现这样的异常 subtask任务就fail重启这个要配置哪些参数可以解决吗？是在flink yaml里面这样配么？那要真是网络问题有什么办法能有效避免这种异常么？

Flink CDC又从0初始化开始了不应该是从ck地方续传么？

Flink CDC任务执行几十分钟数据量传输有几百万了而且ck保存也都成功但不知道为啥cdc任务中间异常后整个record sent又从0初始化开始了不应该是从ck地方续传么？

Flink cdc同步mysql多张表，初始化过程中，内存是如何释放的？

Flink cdc同步mysql多张表，初始化过程中，内存是如何释放的？用增量快照算法，指定的拆分主键，状态后端默认的，TM内存。存储在hashMap。

Flink CDC里cdc整库同步,全量初始化过程超过binlog的保存时间会不会导致数据丢失啊？

Flink CDC里初始化全量数据时没问题增量数据会报错是为什么？
