实时计算 Flink版全量binlog 的相关内容

Flink CDC里你们有调试过全量快照读取+增量binlog的时候吗？

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这个意思是全量阶段也会进行binlog消费吧？

Flink CDC这个意思是全量阶段也会进行binlog消费吧？因为正常消费的太慢 binlog没了导致找不到位点。我看那个算法描述是按chunk 进行select 然后从select前的低位点到select完成的高位点binlog 再和buffer进行合并

Flink CDC全量结束还是会按照之前的binlog位点进行消费而不是进行合并输出？

Flink CDC全量结束还是会按照之前的binlog位点进行消费而不是进行合并输出？那是不是其他表的binlog也会被阻塞消费呀？

Flink CDC全量历史数据比较多，全量同步阶段时间长会同时读取binlog进行合并输出吧？

Flink CDC全量历史数据比较多，全量同步阶段时间长会同时读取binlog进行合并输出吧，比如新增一张表全量同步耗时三个小时，binlog文件只保留近一个小时的，会影响全量到增量的衔接么，会阻塞其它表的binlog采集么？

Flink CDC中第一次启动的时候需要全量后面就是监听binlog增量这个怎么设置？中间存在宕机。

Flink CDC中第一次启动的时候需要全量后面就是监听binlog增量这个怎么设置？中间存在宕机重启了。

Flink CDC有没有办法只同步全量一次，不读binlog？

请问，flink cdc 全量同步不加锁，如果要同步binlog之前的数据的话，是通过select

请问，flink cdc 全量同步不加锁，如果要同步binlog之前的数据的话，是通过select 查表获取全量数据的吗？另外：在同步全量数据的同时，如果数据库还有更新，那么是如何解决的？

Flink CDC说的全量应该是系统中已经有的binlog吧？不是说的是数据库的全量数据

Flink CDC在获取全量数据阶段的时候是基于查询的，还是基于binlog日志的呢？

如果是数据采集的这个阶段的话，是不是依靠什么无锁算法啥的处理一致性的，但是我就是觉得Flink CDC在获取全量数据阶段的时候是基于查询的，还是基于binlog日志的呢？
