Interview

• Introduction
• How did you get involved in the area of data management?
• Most everyone listening knows what S3 is, but can you start by giving a quick summary of what roles it plays in the data ecosystem?
• What are the major generational epochs in S3, with a particular focus on analytical/ML data systems?
  • The first major driver of analytical usage for S3 was the Hadoop ecosystem. What are the other elements of the data ecosystem that helped shape the product direction of S3?
• Data storage and retrieval have been core primitives in computing since its inception. What are the characteristics of S3 and all of its copycats that led to such a difference in architectural patterns vs. other shared data technologies? (e.g. NFS, Gluster, Ceph, Samba, etc.)
• How does the unified pool of storage that is exemplified by S3 help to blur the boundaries between application data, analytical data, and ML/AI data?
• What are some of the default patterns for storage and retrieval across those three buckets that can lead to anti-patterns which add friction when trying to unify those use cases?
• The age of AI is leading to a massive potential for unlocking unstructured data, for which S3 has been a massive dumping ground over the years. How is that changing the ways that your customers think about the value of the assets that they have been hoarding for so long?
  • What new architectural patterns is that generating?
• What are the most interesting, innovative, or unexpected ways that you have seen S3 used for analytical/ML/Ai applications?
• What are the most interesting, unexpected, or challenging lessons that you have learned while working on S3?
• When is S3 the wrong choice?
• What do you have planned for the future of S3?

Interview

• Introduction
• How did you get involved in the area of data management?
• Can you describe what DragonflyDB is and the story behind it?
• What is the core problem/use case that is solved by making a "faster Redis"?
• The other major player in the high performance key/value database space is Aerospike. What are the heuristics that an engineer should use to determine whether to use that vs. Dragonfly/Redis?
• Common use cases for Redis involve application caches and queueing (e.g. Celery/RQ). What are some of the other applications that you have seen Redis/Dragonfly used for, particularly in data engineering use cases?
• There is a piece of tribal wisdom that it takes 10 years for a database to iron out all of the kinks. At the same time, there have been substantial investments in commoditizing the underlying components of database engines. Can you describe how you approached the implementation of DragonflyDB to arive at a functional and reliable implementation?
• What are the architectural elements that contribute to the performance and scalability benefits of Dragonfly?
  • How have the design and goals of the system changed since you first started working on it?
• For teams who migrate from Redis to Dragonfly, beyond the cost savings what are some of the ways that it changes the ways that they think about their overall system design?
• What are the most interesting, innovative, or unexpected ways that you have seen Dragonfly used?
• What are the most interesting, unexpected, or challenging lessons that you have learned while working on DragonflyDB?
• When is DragonflyDB the wrong choice?
• What do you have planned for the future of DragonflyDB?
