Event Processor with Sidekiq

This project processes a list of events using Sidekiq for background job processing. It identifies accounts with reactivations and multiple cancellations.

Setup

1. Clone git Repo.:

   git@github.com:sajjadmurtaza/event_processor.git
   

2. Install Redis: Sidekiq requires Redis to manage job queues. Ensure Redis is installed and running.

3. Install Bundler: If you haven't already, install Bundler:

   gem install bundler

4. Install Dependencies: Run Bundler to install the necessary gems:

   bundle install

Running the Project

1. Start Redis: Ensure Redis is running. You can start it with:

   bundle install
   

2. Start Sidekiq: Run the following command to start Sidekiq:

   bundle exec sidekiq -r ./main.rb -C sidekiq_config.yml
   

3. Rub Tests:

   bundle exec rspec
   

Reason of using Sidekiq

• Future Growth: While the current task is simple, using Sidekiq prepares the system for future scalability.
• Asynchronous Processing
