CockroachDB In Depth with Peter Mattis - Episode 35

Summary

With the increased ease of gaining access to servers in data centers across the world has come the need for supporting globally distributed data storage. With the first wave of cloud era databases the ability to replicate information geographically came at the expense of transactions and familiar query languages. To address these shortcomings the engineers at Cockroach Labs have built a globally distributed SQL database with full ACID semantics in Cockroach DB. In this episode Peter Mattis, the co-founder and VP of Engineering at Cockroach Labs, describes the architecture that underlies the database, the challenges they have faced along the way, and the ways that you can use it in your own environments today.

Interview
  • Introduction
  • How did you get involved in the area of data management?
  • What was the motivation for creating CockroachDB and building a business around it?
  • Can you describe the architecture of CockroachDB and how it supports distributed ACID transactions?
    • What are some of the tradeoffs that are necessary to allow for georeplicated data with distributed transactions?
    • What are some of the problems that you have had to work around in the RAFT protocol to provide reliable operation of the clustering mechanism?
  • Go is an unconventional language for building a database. What are the pros and cons of that choice?
  • What are some of the common points of confusion that users of CockroachDB have when operating or interacting with it?
    • What are the edge cases and failure modes that users should be aware of?
  • I know that your SQL syntax is PostGreSQL compatible, so is it possible to use existing ORMs unmodified with CockroachDB?
    • What are some examples of extensions that are specific to CockroachDB?
  • What are some of the most interesting uses of CockroachDB that you have seen?
  • When is CockroachDB the wrong choice?
  • What do you have planned for the future of CockroachDB?
