Congrats to my former students Chris DeCarolis and Kevin Chen on launching @indent! indent.com/
New post that discusses when you can reasonably expect GPUs to accelerate SQL workloads: starburst.io/blog/will-gpus-…
New post where I discuss some of Chujun Song's benchmarking experiments (done in my lab at UMD) showing the overhead of large JDBC reads in Trino: starburst.io/blog/benchmarki…
I wrote 2 blog posts recently on that discuss using Trino to access data stored in SQL databases and related performance issues.

Congrats to newly minted PhDs from my lab: Cuong (Ethan) Nguyen and Chujun Song (2nd and 4th from the right). Can't wait to see the incredible things you both will accomplish in your next steps ...

Thank you to @daniel_abadi and @kostja_osipov for a great distributed consensus discussion. We've come a long way since #CAP. Do you know about #PACELC?
I'll be speaking at the #ScyllaDB summit (scylladb.com/summit) on the throughput vs. consistency tradeoff in distributed systems on Feb 15.
The grammar police at Starburst (I won't name names) tried to nix my phrase: "It is no longer acceptable to “code, growed, and offload” a dataset" from the post I tweeted earlier today, but I got it in via a special poetry exception.
Thank you @andy_pavlo for the database-themed newborn clothing for our new addition.
Very proud of my student @gangliao101 who recently graduated from my lab at @umdcs and just accepted a full time Senior Researcher position. To find out where --- you will have to follow him 😀
Maryland's primary is tomorrow. Of the three main candidates running on the democratic side, was surprised to see that only @peterfranchot seems to discuss importance of investment in *all* public universities on his Website. Maybe I'm looking in the wrong place for the others?
Agree with much of this advice. Especially that you don't need to network with famous people. Interactions with peers are more likely to lead to long term relationships and many will go on to become famous over time. Further, it's a way for your work to get a grass roots impact.

On my way to SIGMOD --- my first in-person conference since COVID. Can't wait to catch up will all the people in the database community that I haven't seen in way too long ...

and, speaking on PACELC with us tomorrow, I might add. Looking forward to it

Found out this week that there is a wikipedia page about me that somehow I didn't know existed until now. Thank you to whoever contributed to it. en.wikipedia.org/wiki/Daniel…
In light of @VoltronData's 100M series A funding last week, it might be worth revisiting my 2017 and 2018 posts on Apache Arrow: dbmsmusings.blogspot.com/201… and dbmsmusings.blogspot.com/201…
Nice post on isolation levels and consistency from Ben Darnell at @CockroachDB: cockroachlabs.com/blog/db-co…. The basic approach of thinking about isolation and consistency separately was also discussed in my 2019 post: dbmsmusings.blogspot.com/201….
Well, that should remove beyond any shred of doubt that @JustinBorgman is one of the best tech CEOs on the planet. siliconangle.com/2022/02/09/…

@daniel_abadi Delos is Calvin-style determinism as well (after I worked with you I realized it just made more sense than what Tango / Hyder did). Nice to see determinism in more production systems!
