The simplest, batch+message queue

Those SMS clouds should support, such as Alibaba. But you definitely can’t issue 1 million at once. Let’s do it in batches. It’s best to write a dedicated service to do this

1 million is actually not much. Today’s SMS platforms basically support sending 1,000 records at a time. If you send it asynchronously, it only takes a few minutes. I have done something similar before, generating a temporary record for the record you sent. Hash, if the transmission fails, it will be sent again and cannot be sent to the user again.

1 For batch extraction, you can consider fetching every 100 or 1000 IDs at a time, which is faster.
2 Concurrent sending will be involved here. For multi-threaded concurrency, you can read SWOOLE WORKMAN
2.1 The content can be repeated. The SMS service provider provides a batch of 100 messages to be sent concurrently. I guess
2.2 If the content is not repeated, then send it one by one
3 Record the sending results and resend regularly

Look at the maximum amount that the SMS interface can accept per second
and then execute it concurrently:

<code>p1&
p2&
p3&
wait
p4&
p5&
p6&
...
