How to create a Ruby gem that adds Rake tasks

How to create a Ruby gem that adds Rake tasks

Create a gem

One way to do this is to use bundler to scaffold our gem:

bundler gem my_gem

Add rake tasks to our gem

I prefer to put tasks meant to manage the gem itself in lib/tasks, and tasks the gem is meant to provide to gem users in lib/my_gem/tasks.

Austio / The Many Meanings of Event-Driven Architecture.md
Created April 26, 2021 21:19 — forked from xpepper/The Many Meanings of Event-Driven Architecture.md
My notes on the talk "The Many Meanings of Event-Driven Architecture" by Martin Fowler (GOTO 2017)

GOTO 2017 • The Many Meanings of Event-Driven Architecture - Martin Fowler

(the video is here, the original talk notes are here)

At least one of those four patterns are in play when you talk about "event-driven" architectures:

  1. Event Notification: components communicating via events
  2. Event-carried State Transfer: allowing components to access data without calling the source
  3. Event Sourcing: using an event log as the primary record for a system
  4. CQRS: having a separate component for updating a store from any readers of the store

Turning PostgreSQL into a queue serving 10,000 jobs per second

Turning PostgreSQL into a queue serving 10,000 jobs per second

RDBMS-based job queues have been criticized recently for being unable to handle heavy loads. And they deserve it, to some extent, because the queries used to safely lock a job have been pretty hairy. SELECT FOR UPDATE followed by an UPDATE works fine at first, but then you add more workers, and each is trying to SELECT FOR UPDATE the same row (and maybe throwing NOWAIT in there, then catching the errors and retrying), and things slow down.

On top of that, they have to actually update the row to mark it as locked, so the rest of your workers are sitting there waiting while one of them propagates its lock to disk (and the disks of however many servers you're replicating to). QueueClassic got some mileage out of the novel idea of randomly picking a row near the front of the queue to lock, but I can't still seem to get more than an an extra few hundred jobs per second out of it under heavy load.

So, many developers have started going straight t
