The Pragmatic Engineer published an interview with Peter Mattis, Cockroach Labs co-founder and CTO, about distributed databases, storage engineering and AI-assisted coding. Mattis discusses examples from Gmail, Google’s Colossus storage system and CockroachDB, while the interview’s claims about productivity and performance remain attributed to him or the report.
The Pragmatic Engineer has published an interview with Peter Mattis, the co-founder and CTO of Cockroach Labs, about the engineering tradeoffs behind distributed databases and storage systems. The discussion draws on Mattis’s work at Google and his current experience with AI coding tools, offering practitioners examples of how systems are designed for speed, reliability and correctness at scale.
Mattis recounts work on storage at Google, including Gmail’s early use of B-trees to track email threads and unread counts. The report says incoming messages were matched to threads through the search index, with B-trees used to manage thread data. The interview uses this example to show how data structures can serve particular needs inside a production system.
The discussion also covers Colossus, Google’s successor to the Google File System. According to the report, Mattis and colleagues introduced Reed–Solomon erasure coding in a distributed file system. The system stored data twice instead of keeping three full copies, while increasing redundancy; the report puts the reduction in storage overhead at 33%.
Mattis also describes replacing standard library structures in performance-sensitive settings. The report says he built a B-tree with similar semantics to C++’s std::map, which he said was faster and used less memory, and later developed a Swiss Table implementation that outperformed Go’s map in his work. The Go team helped complete that implementation, which was subsequently incorporated into the Go library, according to the report.
Storage Choices at Google Scale
The examples matter because distributed databases have to balance storage cost, redundancy and speed across many machines. Mattis’s account shows that those outcomes can depend on choices at several levels: how data is encoded across a file system, how records are organized in memory, and how much network delay a system can tolerate.
The interview also connects those engineering decisions to the work of database developers today. Mattis is a co-founder and CTO of Cockroach Labs, which builds a distributed database, and the report says B-trees recur in systems such as Gmail’s storage, Google data structures and CockroachDB’s range index. The examples are his professional recollections as presented in the interview; they do not establish that a single data structure or storage design is right for every workload.
Mattis’s comments on AI speak to a separate change in engineering practice. He says AI has brought him back to writing code after his role shifted toward management, and he feels more productive without a drop in quality. Those are his assessment of his own work, not a measured result that can be applied to all engineers or teams.

From GIMP to Google Storage
Mattis first became known as an open-source software creator. He and his college roommate Spencer Kimball created GIMP, an image editing program; the report says the first version of the Google logo was made using it. Mattis later joined Google after initially turning down an offer because of the commute from San Francisco to Mountain View, according to his account in the interview.
At Google, his work included Gmail and distributed storage. The report notes that Gmail launched in 2004 with 1GB of free email storage, an amount that seemed unusually generous at the time. It also describes how B-trees supported email-thread storage. These earlier examples provide context for the interview’s focus on practical system design rather than a new product announcement.
The episode ranges beyond databases to engineering practice, including code review, learning and AI tools. Its accompanying page also points readers to a separate turbopuffer engineering team project to redesign its storage architecture. That promotion is distinct from Mattis’s interview and does not establish a connection between the two projects.
“There’s always going to be someone else working on your idea.”
— Peter Mattis, as quoted in The Pragmatic Engineer
What the Interview Does Not Measure
The source is an interview and report, not a comparative study of database architectures or AI productivity. It does not provide benchmark methods, workload details or independent measurements for the performance claims about Mattis’s data structures. The 33% storage-overhead figure is reported without a detailed calculation or deployment scope in the supplied material.
The report also does not quantify Mattis’s coding output with AI or compare code quality against a defined baseline. His view that AI has increased his productivity without reducing quality remains a personal assessment. The source gives no publication date, and it does not specify whether the interview’s discussion of current network speeds or AI tools has since changed.
Where Readers Can Follow Up
The interview is available through The Pragmatic Engineer, which says listeners and viewers can find the episode on YouTube, Apple and Spotify; a transcript and episode timestamps are also available on its page. Readers interested in Mattis’s engineering background can follow the episode’s discussion of Gmail storage, Colossus and B-tree design.
The source does not announce a new Cockroach Labs product, release or timetable tied to the interview. Any further developments in the company’s database work or Mattis’s use of AI would need to be confirmed through later statements or reporting.
Key Questions
Who is Peter Mattis?
Peter Mattis is the co-founder and CTO of Cockroach Labs. The report also identifies him as an original creator of GIMP and a former Google engineer who worked on Gmail and distributed storage.
What database topics does the interview cover?
The discussion covers B-trees, distributed storage, reliability and performance, drawing on examples from Gmail, Google’s Colossus system and CockroachDB.
What did Colossus change, according to the report?
The report says Colossus used Reed–Solomon erasure coding to store data twice rather than keeping three full copies, reducing storage overhead by 33% while increasing redundancy.
What does Mattis say about AI and coding?
Mattis says AI has brought him back to writing code after his work shifted toward management. He reports feeling more productive without a drop in quality; the source does not provide independent measurements of that assessment.
