Long and Short Polling

SQS’s API is all HTTP based. This means that when our queue workers poll SQS for a new job, it’s making an HTTP request to the SQS API.

By default, this does “short polling” – if no job is available when the HTTP request is made, SQS immediately returns an empty response.

Long polling allows you to keep an HTTP request open for a certain amount of time. While the HTTP request is open, SQS may send a job to the queue worker at any time.

Laravel doesn’t do any long polling, but there is something important to know here.

If you use the SQS queue driver, you may see that some jobs take a while to get processed – as if the queue worker can’t find a new job. This is related to how SQS is scaled within AWS.

Here’s the relevant thing to know, from the SQS docs:

With short polling, the ReceiveMessage request queries only a subset of the servers (based on a weighted random distribution) to find messages that are available to include in the response. Amazon SQS sends the response right away, even if the query found no messages.

With long polling, the ReceiveMessage request queries all of the servers for messages. Amazon SQS sends a response after it collects at least one available message, up to the maximum number of messages specified in the request. Amazon SQS sends an empty response only if the polling wait time expires.

It turns out that with long polling, we’re likely to get jobs more quickly as it polls all of the SQS servers that may contain our jobs!

However, Laravel doesn’t support long-polling out of the box. Luckily, we can do something about that. There’s a little note in the bottom of the docs linked above:

Short polling occurs when the WaitTimeSeconds parameter of a ReceiveMessage request is set to 0 in one of two ways:

• The ReceiveMessage call sets WaitTimeSeconds to 0.
• The ReceiveMessage call doesn’t set WaitTimeSeconds, but the queue attribute ReceiveMessageWaitTimeSeconds is set to 0.

Onboarding tools

1 – Assist them in having their work environment ready

#1 –  create a company email for new employee

#2 –   Provide a GIT repository account

#3 –  provide local development environment – Sandboxes account

#4 – provide Jira Account / access

#5 – provide Confluence account

#6 –  provide VPN access

#7 –  provide Chat/Slack access

2- Guideline Programming

3 – Recommendation for integrating  developers in the group

*  pull request / code review against programming guideline

*  write functional test on the latest/pending release

* write documentation phpdocs / swagger / add documentation

4 – Programming guideline

 Principles are guiding this methodology

- Readability
- Quality Assurance
- Logic
- Reusable code

 Readability

PSR-2 code styling
Function no longer than 50 lines
PHP doc Block
TypeHint your functions

More information:

For better code readability we suggest PSR-2 code styling to be applied. We consider a function bigger than 25 lines is not an efficient function. For engaging this methodology we recommend 50 lines maximum per function. DocBloc are essentials. Swagger in a case of API writing is essential to be present.
A developer should be able to explain his work easily and quickly and should use materials to do so

Quality Insurance

No PHP error message
No PHP Warning messages
No PHP Notices
No hardcore credentials
Unit Testing
Details:

When executing the code we expect the quality assurance team to verify that no PHP errors, warnings, notices are produced. We also expect the QA team to go throughout the code to verify that no hardcore credentials are present within the code. Unit Test writing should be edited by QA team preferably

Logic

DRY (do not repeat yourself)
KISS (Keep it Stupid Simple)
SOLID principles

 Reusable Code

Use PHP throw exception
Use Object oriented techniques
Use static function

Use PHP throw exception
Use Object oriented techniques
Use static function

Add the following your PHP too get rid of PHP notices, warnings

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

Create/Update endpoint in a restful api

The PUT API methodology should be appropriate for an upsert

According to the HTTP specification:

The PUT method requests that the enclosed entity be stored under the supplied Request-URI. If the Request-URI refers to an already existing resource, the enclosed entity SHOULD be considered as a modified version of the one residing on the origin server. If the Request-URI does not point to an existing resource, and that URI is capable of being defined as a new resource by the requesting user agent, the origin server can create the resource with that URI.

I therefore think that the use of PUT for an insert or update is perfectly legitimate, provided that in both cases the URI is known in advance. If you’re using the key as part of the URI (as k1 in http://www.somewhere.com/resources/k1) this should be the case. To be ideally RESTful, however, a GET to the same URL should also allow you to download the resource.
