即使删除的消息等于收到的消息，SQS大小也会增加 [英] SQS Size growing even though messages deleted is equal to messages received

问题描述

如果删除的消息数量等于收到的消息数量，那么SQS队列中消息数量增加的原因可能是什么？

What can be the reason for number of messages in a SQS queue increasing if the number of messaged deleted is equal to number of messages received?

推荐答案

来自适用于Amazon SQS的CloudWatch指标-Amazon Simple Queue Service ：

• NumberOfMessagesDeleted：对于使用有效收据句柄的每个成功删除操作，Amazon SQS都会发出 NumberOfMessagesDeleted 指标，包括重复删除。


• NumberOfMessagesReceived：调用 ReceiveMessage 操作。


• NumberOfMessagesSent：添加到队列中的消息数。

• NumberOfMessagesDeleted: Amazon SQS emits the NumberOfMessagesDeleted metric for every successful deletion operation that uses a valid receipt handle, including duplicate deletions.
• NumberOfMessagesReceived: The number of messages returned by calls to the ReceiveMessage action.
• NumberOfMessagesSent: The number of messages added to a queue.

或者，简单地说：

• 已发送是指发送到队列


• 已收到表示从队列中检索


• 已删除意味着已从队列中删除的队列

• Sent means sent to the queue
• Received means retrieved from the queue
• Deleted means removed from the queue
