The following table lists quotas related to standard queues.
Quota Description Delay queue The default (minimum) delay for a queue is 0 seconds. The maximum is 15 minutes. Listed queues 1,000 queues perListQueues
request. Long polling wait time The maximum long polling wait time is 20 seconds. Messages per queue (backlog) The number of messages that an Amazon SQS queue can store is unlimited. Messages per queue (in flight)
For most standard queues (depending on queue traffic and message backlog), there can be a maximum of approximately 120,000 in flight messages (received from a queue by a consumer, but not yet deleted from the queue). If you reach this quota while using short polling, Amazon SQS returns the OverLimit
error message. If you use long polling, Amazon SQS returns no error messages. To avoid reaching the quota, you should delete messages from the queue after they're processed. You can also increase the number of queues you use to process your messages. To request a quota increase, submit a support request.
A queue name can have up to 80 characters. The following characters are accepted: alphanumeric characters, hyphens (-
), and underscores (_
).
Queue names are case-sensitive (for example, Test-queue
and test-queue
are different queues).
We don't recommend adding more than 50 tags to a queue. Tagging supports Unicode characters in UTF-8.
The tagKey
is required, but the tag Value
is optional. The tag Key
and tag Value
are case-sensitive. The tag Key
and tag Value
can include Unicode alphanumeric characters in UTF-8 and whitespaces. The following special characters are allowed: _ . : / = + - @
The tag Key
or Value
must not include the reserved prefix aws:
(you can't delete tag keys or values with this prefix). The maximum tag Key
length is 128 Unicode characters in UTF-8. The tag Key
must not be empty or null. The maximum tag Value
length is 256 Unicode characters in UTF-8. The tag Value
may be empty or null. Tagging actions are limited to 30 TPS per AWS account. If your application requires a higher throughput, submit a request.
