1 1 KB is measured as 1000 bytes. Messages can include up to ~100 bytes of internal metadata that counts towards total message limits.
2 The maximum message throughput per queue will continue to increase during the beta period.
3 Exceeding the maximum message throughput will cause the send()
and sendBatch()
methods to throw an exception with a Too Many Requests
error until your producer falls below the limit.
4 Messages in a queue that reach the maximum message retention are deleted from the queue. Queues does not delete messages in the same queue that have not reached this limit.
