amazon-dynamodb - DynamoDB TTL - 删除项目时

Question

dynanodb 是否有删除过期行最多需要 48 小时的限制？
http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/howitworks-ttl.html

由于我想在从 dynamo db 表中删除一行时执行 Lambda，所以这意味着我的 lambda 触发器最多可能需要 48 小时？

Answer 1

是的，根据 link你发了

DynamoDB typically deletes expired items within 48 hours of expiration. The exact duration within which an item truly gets deleted after expiration is specific to the nature of the workload and the size of the table. Items that have expired and not been deleted will still show up in reads, queries, and scans.

如果您在删除时有一个 Lambda 触发器，它将在删除时发生，这可能是 within 48 hours of expiration (根据您发送的链接)。
