Columnar file formats like Parquet/ORC are ubiquitous. Our VLDB paper with Xinyu Zeng + Huanchen Zhang + Wes McKinney studies their internals.
TLDR: They're not optimized for modern hardware. Something new is needed.

My #1 PhD student Matt Butrovich successfully completed his PhD defense. Thanks to the committee (@pateljm billions of packets Sam Madden). Matt's thesis is on accelerating databases with eBPF (telemetry, proxies, OLTP stores).
You have 60 days to hire him. Expect fierce competition.

Thanks for this hot take dude who doesn't know the 60 year history of databases. H/T Prem Viswanathan
Mike and I have a WIP paper that analyzes all the (failed) attempts to replace SQL + relational model. This tweet has motivated me to finish it and submit it.

Why is PACMMOD using single-column ACM style, and requiring SIGMOD/PODS 2024 camera-ready papers to reformat last minute? This is wrong at so many levels.
