amazon-web-services - Amazon Kinesis 记录的 ApproximateArrivalTimestamp 的准确度如何？

Question

去年 AWS announced Kinesis 记录的服务器端时间戳。

这个时间戳有多准确？

Answer 1

Each Amazon Kinesis record includes a value, ApproximateArrivalTimestamp, that is set when an Amazon Kinesis stream successfully receives and stores a record. This is commonly referred to as a server-side timestamp, whereas a client-side timestamp is set when a data producer creates or sends the record to a stream. The timestamp has millisecond precision. There are no guarantees about the timestamp accuracy, or that the timestamp is always increasing. For example, records in a shard or across a stream might have timestamps that are out of order.
