实时计算 Flink版产品使用合集之增量同步速度较慢，导致延迟增加，该如何优化

问题一：Flink CDC增量只能是1,但是binlog数量很大延迟到小时级别有什么建议吗？ Flink CDC增量只能是1,但是binlog数量很大延迟到小时级别有什么建议吗？参考答案：如果这么大的话，适当调整下debezium的采集数据大小，flink单并行度处理这些数据，还是easy的，是不是上游采集的太慢造成的问题。 ...

Flink CDC里Oracle 增量同步延迟很大，怎么优化一下？

Flink CDC里Oracle 增量同步延迟很大，怎么优化一下，'debezium.log.mining.strategy' = 'online_catalog','debezium.log.mining.continuous.mine' = 'true'这两个已经加了

Flink CDC中这个oracle全量、增量同步的效率还是不太行有优化思路吗？

Flink CDC中这个oracle全量、增量同步的效率还是不太行，不管是用springboot集成，直接java -jar独立启动还是在webUI上面提交jar启动，感觉比DataX + OGG的方案要低了不止一两个数量级，有优化思路吗？给了8个G内存，并行度调高速度还是一样的不知道是我哪里写的有问题。
