Summary

All of the advancements in our technology is based around the principles of abstraction. These are valuable until they break down, which is an inevitable occurrence. In this episode the host Tobias Macey shares his reflections on recent experiences where the abstractions leaked and some observances on how to deal with that situation in a data platform architecture.

Hello and welcome to the Data Engineering Podcast, the show about modern data management RudderStack helps you build a customer data platform on your warehouse or data lake. Instead of trapping data in a black box, they enable you to easily collect customer data from the entire stack and build an identity graph on your warehouse, giving you full visibility and control. Their SDKs make event streaming from any app or website easy, and their extensive library of integrations enable you to automatically send data to hundreds of downstream tools.

Introduction impact of community tech debt

hive metastore new work being done but not widely adopted

tensions between automation and correctness data type mapping

integer types complex types naming things (keys/column names from APIs to databases)

disaggregated databases - pros and cons

flexibility and cost control not as much tooling invested vs. Snowflake/BigQuery/Redshift

data modeling

dimensional modeling vs. answering today's questions

What are the most interesting, unexpected, or challenging lessons that you have learned while working on your data platform? When is ELT the wrong choice? What do you have planned for the future of your data platform?
