Massive file upload using JQueryUpload + Nginx + Rails + Sidekiq

Massive file upload using JQueryUpload + Nginx + Rails + Sidekiq

The goal: Upload several files (virtually big files) to a Rails application without compromising the user experience.

Architecture

jQuery File Upload + Nginx + Rails (Carrierwave) + Sidekiq

  1. jQuery File Upload (http://blueimp.github.io/jQuery-File-Upload/)

A small nokogiri xml reader DSL.
# A small DSL for helping parsing documents using Nokogiri::XML::Reader. The
# XML Reader is a good way to move a cursor through a (large) XML document fast,
# but is not as cumbersome as writing a full SAX document handler. Read about
# it here: http://nokogiri.org/Nokogiri/XML/Reader.html
#
# Just pass the reader in this parser and specificy the nodes that you are interested
# in in a block. You can just parse every node or only look inside certain nodes.

# A small example:

Profiling memory leaky Sidekiq applications with Ruby 2.1

My largest Sidekiq application had a memory leak and I was able to find and fix it in just few hours spent on analyzing Ruby's heap. In this post I'll show my profiling setup.

As you might know Ruby 2.1 introduced a few great changes to ObjectSpace, so now it's much easier to find a line of code that is allocating too many objects. Here is great post explaining how it's working.

I was too lazy to set up some seeding and run it locally, so I checked that test suite passes when profiling is enabled and pushed debugging to production. Production environment also suited me better since my jobs data can't be fully random generated.

So, in order to profile your worker, add this to your Sidekiq configuration:

Принципы разработки Амплифера

Тут перечислены не законы, последние слово всегда за здравым смыслом. Тут перечислены лишь направление, куда надо стремиться. Принципы, которые должны помочь, когда не знаешь, что выбрать.

Ценности

  1. Пользователь. Если что-то сильно мешает UX или есть критическая ошибка, то в первую очередь мы спасаем пользователей. Для этого иногда надо взять ответственность на себя, переубедить толпу, написать плохой код.
