I used this PostgreSQL for Windows Installer to install PostgreSQL onto my computer. (Note: you’ll need to sign up for Windows Insider, but it’s free and took just a few minutes for me to do.)

Here's the link to the Microsoft documentation on how to install the Windows Subsystem for Linux and install the Ubuntu app which is used to access it. The main benefit of using the WSL is that we can 1) use Linux command-line tools and applications and 2) avoid the potential headache of navigating through Windows Powershell. The Windows Subsystem for Linux (or WSL) allows developers to run a Linux environment directly from Windows, while Ubuntu is an operating system that’s based on Linux. Install Ubuntu on the Windows Subsystem for Linux (WSL)įirst things first, let’s define a few key things. So without further ado, here’s how we were able to get Rails successfully installed on Windows:ġ. Well, it turned out to be quite a confusing process, but after much head-scratching and jumping through many Google search hoops, I’m happy to report that we succeeded in getting everything up and running. The only problem? I was stuck with my personal Windows computer while waiting for a company MacBook to be shipped to me.Īlas, my first challenge: Getting Rails 6 and PostgreSQL working on Windows.

I had to use transaction mode with prepared_statement option disabled.During my first week as a Junior Software Engineer with the Orbit team, I had many things to do to get into the overall swing of things, and one of the most important tasks was getting our Rails application set up on my local machine.

Without the right pool/thread size, Rails will throw ActiveRecord::ConnectionTimeoutError error.Both Rails and PgBouncer has an option to disconnect idle connections.PgBouncer will increase the connections after I ran the benchmark couple of times, but never reached the max.Without PgBouncer, Rails will immediately open all possible connections.Opening rails console won't immediately open a connection.These are some the notes based on my observations: So, we need a total of 10 + 40 = 50 connections.Īgain, we need to ensure proper DB pool size is set. DB pool should be set to 20 in this case. bundle exec sidekiq -C config/sidekiq/data.ymlĪssuming concurrency set to 20 each in those configs, we need to have 2 x 20 = 40 connections.bundle exec sidekiq -C config/sidekiq/payment.yml.We also need to set the DB pool size to 5. This means, we need to have at least 2x5 = 10 connections. In this exercise, I'm using WEB_CONCURRENCY.A process is something like how many puma/sidekiq process that you have.Once we have figured that out, we need to think about the amount of process that we will have: So, there's a chance the web might have bigger value unless you can specify different config between the worker and the web server (assuming they live in different server)

Sidekiq might have different concurrency, so, if the concurrency is set to 20, then you need to increase the pool size to accomodate that.But you might different value when you have a background job, e.g: Sidekiq.If you set RAILS_MAX_THREAD to 10, then, that's the amount the pool size needed.The pool size in database.yml depends on how many threads/concurrency that you set.The first part is to figure out the max connections per process: Enter fullscreen mode Exit fullscreen modeĬalculating the amount of database needed
