Something like 4 years of work, by a team of 40, wasted by stupid decisions.&lt;p&gt;They included:
  o Using Cassandra to store 6 million rows of highly structured, mostly readonly data&lt;p&gt;&lt;pre&gt;&lt;code&gt;  o hosting it on real tin, expensive tin, in multiple continents (looking at &amp;gt;million quid in costs)

  o writing the stack in java, getting bored, re-writing it as a micro service, before actually finishing the original system

  o getting bored of writing micro services in java, switching to scala, which only 2&amp;#x2F;15 devs knew.

  o writing mission critical services in elixir, of which only 1 dev knew. 

  o refusing to use other teams tools

  o refusing to use the company wiki, opting for thier own confluence instance, which barred access to anyone else, including the teams they supported&lt;/code&gt;&lt;/pre&gt;</text><parent_chain><item><author>pjmlp</author><text>Fashion driven development and not understanding how to actually make use of SQL.</text></item><item><author>nemild</author><text>The Guardian example was heavily used by MongoDB as a case study to pitch their database to others in 2011:&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.mongodb.com&amp;#x2F;customers&amp;#x2F;guardian&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.mongodb.com&amp;#x2F;customers&amp;#x2F;guardian&lt;/a&gt;&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.mongodb.com&amp;#x2F;presentations&amp;#x2F;mongodb-guardian&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.mongodb.com&amp;#x2F;presentations&amp;#x2F;mongodb-guardian&lt;/a&gt;&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.slideshare.net&amp;#x2F;tackers&amp;#x2F;why-we-chose-mongodb-for-guardiancouk&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.slideshare.net&amp;#x2F;tackers&amp;#x2F;why-we-chose-mongodb-for-...&lt;/a&gt;&lt;p&gt;And reupping my previous, three-part series on MongoDB:&lt;p&gt;&lt;i&gt;On MongoDB&lt;/i&gt;&lt;p&gt;NoSQL databases were the future.
