Untuk mengubah visibilitas batas waktu pesan

Contoh ini mengubah visibilitas batas waktu pesan yang ditentukan menjadi 10 jam (10 jam* 60 menit * 60 detik).

Perintah:

aws sqs change-message-visibility --queue-url https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyQueue --receipt-handle AQEBTpyI...t6HyQg== --visibility-timeout 36000

Output:

None.
