Untuk membuat antrian
Contoh ini membuat antrian dengan nama yang ditentukan, menetapkan periode penyimpanan pesan menjadi 3 hari (3 hari* 24 jam* 60 menit * 60 detik), dan mengatur antrian surat mati antrian ke antrian yang ditentukan dengan jumlah penerimaan maksimum 1.000 pesan.
Perintah:
aws sqs create-queue --queue-name
MyQueue
--attributesfile://create-queue.json
File masukan (buat-antrean.json):
{ "RedrivePolicy": "{\"deadLetterTargetArn\":\"arn:aws:sqs:us-east-1:80398EXAMPLE:MyDeadLetterQueue\",\"maxReceiveCount\":\"1000\"}", "MessageRetentionPeriod": "259200" }
