Slack Data Platform with Josh Wills Holiday Repeat

Originally published January 10, 2020

Slack is a messaging platform for organizations. Since its creation in 2013, Slack has quickly become a core piece of technology used by a wide variety of technology companies, groups, and small teams. 

The messages that are sent on Slack are generated at a very high volume, and are extremely sensitive. These messages must be stored on Slack’s servers in a way that does not risk a message from one company accidentally being accessible to another company. The messages must be highly available, and they also must be indexed for search.

When Slack was scaling, the company started to encounter limitations in its data infrastructure that the company was unsure how to solve. During this time, Josh Wills was the director of data engineering at Slack, and he joins the show to retell the history of his time at Slack, and why the problem of searching messages was so hard. 

Josh also provides a great deal of industry context around how engineers from Facebook and Google differ from one another. When Slack was starting to become popular, the company quickly began to attract engineers from both of those companies. Facebook and Google have distinct solutions for how they have tackled the problems of data engineering.
