Jobs GORUCO 2018, @kirshatrov
class ExampleJob < ActiveJob::Base def perform ... end end GORUCO

class ExampleJob < ActiveJob::Base def perform Product.all.find_each do |product| product.sync_and_refresh
end end end GORUCO 2018, @kirshatrov
class ExampleJob < ActiveJob::Base def perform Product.all.find_each do |product| product.sync_and_refresh
end end end minutes? hours? days? GORUCO 2018, @kirshatrov
Long-running jobs GORUCO 2018, @kirshatrov
Long-running jobs — Deploys and termination GORUCO 2018, @kirshatrov
Long-running jobs — Deploys and termination — Abort and re-enqueue
— Progress lost GORUCO 2018, @kirshatrov
GORUCO 2018, @kirshatrov
Long-running jobs — Deploys and termination — Abort and re-enqueue
— Progress lost — Job may never complete GORUCO 2018, @kirshatrov
Long-running jobs — Deploys and termination — Abort and re-enqueue
— Progress lost — Job may never complete — Capacity and worker starvation GORUCO 2018, @kirshatrov
Long-running jobs — Deploys and termination — Abort and re-enqueue
— Progress lost — Job may never complete — Capacity and worker starvation — Cloud ☁ GORUCO 2018, @kirshatrov
Why is it taking long? Because it iterates over a
long collection. GORUCO 2018, @kirshatrov
What if jobs were interruptible and resumable? GORUCO 2018, @kirshatrov
Split the job definition 1. Collection to process 2. Work
to be done GORUCO 2018, @kirshatrov
Split the job definition 1. Collection to process ≫ Product.all
2. Work to be done GORUCO 2018, @kirshatrov
Split the job definition 1. Collection to process ≫ Product.all
2. Work to be done ≫ product.sync_and_refresh GORUCO 2018, @kirshatrov
class ExampleJob < ActiveJob::Base include Iteration def collection Product.all end
def each_iteration(product) product.sync_and_refresh end end GORUCO 2018, @kirshatrov
— def perform — collection — each_iteration GORUCO 2018, @kirshatrov
Product.all cursor: 1 GORUCO 2018, @kirshatrov
Product.all cursor: 2 GORUCO 2018, @kirshatrov
Product.all cursor: 3 GORUCO 2018, @kirshatrov
Product.all cursor: 4 GORUCO 2018, @kirshatrov
Product.all cursor: 5 GORUCO 2018, @kirshatrov
Product.all cursor: 450123 GORUCO 2018, @kirshatrov
class WhateverJob < ActiveJob::Base include Iteration def collection Enumerator.new do
|enum| 3.times do |n| enum << n end end end def each_iteration(n) # do something three times! end end GORUCO 2018, @kirshatrov
Endless possibilities — Interrupt and resume at any moment —
Progress tracking — Parallel computations — Throttling by default GORUCO 2018, @kirshatrov
Benefits for the infrastructure — Keep supporting long-running jobs —
Success for Cloud runtime — Make scale invisible for developers — Opportunities to save money with short-living instances in Cloud GORUCO 2018, @kirshatrov
Thank you! @kirshatrov GORUCO 2018, @kirshatrov
