RUBY 476: SQL, Arel and the Dark Side of ActiveRecord with Eric Hayes

In this episode of Ruby Rogues, Eric Hayes joins us with the story of his journey into the dark, undocumented depths of Arel, ActiveRecord’s private API. We learn why writing custom SQL queries in 2020 can make sense and how to unlock the more powerful features of modern databases without resorting to SQL strings. Eric tells us how he manages the potential pitfalls of using Arel and achieves massive performance wins for difficult queries on large databases.SponsorsAudible.comCacheFlyPanelDave KimuraJohn EppersonLuke StuttersCharles Max WoodGuestEric HayesLinkshttps://devhints.io/arel nice little cheat sheethttps://astexplorer.net/https://en.wikipedia.org/wiki/Visitor_patternhttps://twitter.com/ehayesPicksLuke Stutters:https://www.amazon.com/Micsig-DP10013-Differential-Attenuation-Tektronix/dp/B074K4XPW3Chuck:http://podcastplaybook.co/mostvaluable.devAmazon: Lightbringer SeriesNeewer 2 Packs Dimmable Bi-Color 480 LED with U Bracket Professional Video Light for Studio, YouTube Outdoor Video Photography Lighting Kit, Durable Metal Frame,3200-5600K, CRI 96John Epperson:BuckeyeballsDave Kimura::https://www.elgato.com/en/gaming/stream-deckhttps://www.philips-hue.com/en-usEric Hayes:https://www.playgoodsudoku.com/https://www.ansiblefordevops.com/Follow Ruby Rogues on Twitter > @rubyrogues Special Guest: Eric Hayes.
