Research on best way to send efficient http request, and control over sending mail limit.

Way of sending Simplenews module email

• Triggered the sending mail by cron job, where it reads one by one
  • The recipient and mail content, send mail then update the status, that mail has been sent to that recipient or it is failed.

Email Sending in Amazon

• Send one http request to call Query API action SendEmail, so if we have 100 recipients, then Query API will be called 100 times.
• If we send mail single mail with multiple recipients, if mail content is same, then we can send mail to 100 recipient in two times. [Max 50 per request], But in this case all recipient will have the other recipient address, which is not desired [According to me].

So by studying above points, we have some conclusion.

• We have to send one request for each recipient even if mail content is same.
• So for controlling and sending maximum mail with controlled sending rate, we have to control http request.
• For sending request to web service, I am thinking to use Guzzle php http://guzzlephp.org/index.html.
  • It provides best way of sending request to web service client. http://guzzlephp.org/webservice-client/webservice-client.html
  • Request can be sent in batch. http://guzzlephp.org/batching/batching.html
  • I need some time to study guzzle and implement it.

I have been studying Guzzle php since 1 and half day.

• I have wasted 2-3 hours to just send http client request. As php classes are not getting auto loading. http://guzzlephp.org/http-client/client.html
• Then study sending request via batch, and registering event listener. http://guzzlephp.org/batching/batching.html
• Then studied send request via web service client an created webservice client via Service Builder. But Here I got confused. So if you have time, so please help me.

For this you have to see these links, then I can explain my confusion http://guzzlephp.org/webservice-client/webservice-client.html#service-builder http://guzzlephp.org/webservice-client/using-the-service-builder.html.

I have called Query API via HTTP requests in three method, and tested more than 10 times

• I have create a method, which is calling two Query API's action after interval of 1 second.
• I called this function, and recorded Total Time from http response Header object.

Using Pecl_http extension

• 1st query api action : 3.22 [don't know unit of time]
• 2nd query api action: 0.72

Using Guzzle normal Client Request object

• 1st query api action : 1.66
• 2nd query api action: 2.053

Using Guzzle Batch feature Client Request object

• 1st query api action : 0.38998
• 2nd query api action: 0.604474

So I think we have to use last one method for http sending request. Here we can send multiple request parallel via batch feature.

Batching

• Guzzle provides a fairly generic and very customizable batching framework that allows developers to efficiently transfer requests in parallel.
• When I studied code of Guzzle implementing, I got, that they are using php spl queue class. => Doubly linked list. http://guzzlephp.org/batching/batching.html#batching

@sumeetpareek @mukeshagarwal @basantsharma : Please comment here, meanwhile I am implementing Guzzle batch feature.
