Flink CDC中，在支持分片独立消费的CDC binlog数据源中，如何高效地将各分片的offset以JSON格式或其他合适方式存储在SourceRecord的sourceOffset Map中？对于具有shardId和pos属性的CDC记录，应如何设计并更新offsetMap以跟踪每个分片的消费位置？

Flink CDC里指标，我只想存储一个值，比如最大的处理时间，我有个函数可能很耗时怎么办？

Flink CDC里flink指标，我只想存储一个值，比如最大的处理时间，我有个函数可能很耗时，我想从Flink UI 指标中直接看到比如这个耗时指标，并不是累加的，有没有哪个指标是可以使用的？
