Test Mailing service

In current configuration the service can:

• check 6000 emails per hour (that is about 140000 per day or 4 millions per month)
• send the same number of emails per hour
• the load is evenly distributed over time

Set CHECK_THREAD_MAX=100 and SEND_THREAD_MAX=20 environment variable for php docker container to manage service capabilities (maximum sum of threads is 300).

Installation

• Install Docker
• Clone the repo to the project directory
• Run docker-compose up in the project directory

Usage

• Open dashboard on localhost
• Cron job is planned automatically
  • Once an hour worker plan a batch of emails to be processed within next hour to evenly distribute the load
  • Another worker checks for emails in the queue (every minute by cron) and process them in parallel threads
  • Check and send workers and queues are separated and do not conflict with each other
• Dashboard displays general statistics, check and mailing progress

Database

• MySQL server is available on IP 127.0.0.1 and port 3306

Developers

• You can adjust servers IPs and ports in docker-compose.yml if it conflicts with your local environment
• Random data is automatically generated (1 million users), set USER_RANDOM_MAX=1000000 environment variable for php docker container to change number of users
• To speed up testing, set USER_SAMPLE_DATA=true environment variable for php docker container (set by default)
