在Flink CDC中，我加了那个参数，初始化拉取的时候是返回了clob类型的数据，增量变更数据？

在Flink CDC中，我加了那个参数，初始化拉取的时候是返回了clob类型的数据，增量变更数据，返回__debezium_unavailable_value这么个数据，怎么解决？

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，什么时候开始增量？

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）

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？
