ruby-on-rails sidekiq caching performance ci-cd Ruby

I just started working with I'm experimenting with I've looked through the documentation and I'm still confused about I've been banging my head against this for hours....... During development of our CI/CD pipeline, I noticed that the legacy codebase built on Rails 6.1 is introducing significant delays in our build process. The application has a mixture of synchronous and asynchronous jobs, utilizing Sidekiq for background processing. I’ve been trying to isolate the specific parts of the job that are causing bottlenecks, particularly as we push towards more automated testing and deployment. In my initial attempts, I used the following Sidekiq configuration to manage retries: ```ruby Sidekiq.configure_server do |config| config.error_handlers << Proc.new { |ex, ctx| # custom error logging } end ``` While this setup helps with error management, the job still takes longer than expected. Profiling the app led me to identify a few methods with high execution times. Here’s one of the more troublesome methods: ```ruby def process_data(data) data.each do |item| # Simulating a long-running task sleep(1) # Process item end end ``` Replacing `sleep(1)` with a more efficient approach could potentially lower execution time. However, I’m unsure how best to refactor this method without altering its intended functionality or risking data integrity. Additionally, I’ve implemented caching with Rails.cache to reduce data fetch times, but the cache invalidation logic is still a bit convoluted. Currently, I’m using a simple `Rails.cache.fetch` block, but it doesn’t account for cache expirations effectively: ```ruby Rails.cache.fetch('data_key') do fetch_data_from_db end ``` I’m considering switching to a more explicit cache expiration strategy or even using the low-level store APIs for finer control. Has anyone tackled similar issues with legacy Rails code, particularly in optimizing Sidekiq jobs and caching strategies? Any best practices you could share would be greatly appreciated! My development environment is macOS. What am I doing wrong? Thanks for taking the time to read this!
