How can you slow down a program? And perhaps more importantly, why would you? Blog post on our upcoming @VMIL2025 paper. stefan-marr.de/2025/08/how-to… The research was led by @Humphrey_HCB.
@andrewlamb1111 One improvement regarding benchmaxxing is having thousands of diverse benchmark queries instead of dozens. Plugging the new SQLStorm paper below ;)
Mutli-level merge sort queued up for DataFusion 50.0.0 next month: github.com/apache/datafus… Thanks to @rluvaton and Yongting You
I'm excited to share that our paper (in collaboration with @peterabcz ) has been accepted at VLDB 2025 in London and will be presented there: The FastLanes File Format In this paper, we introduce the FastLanes file format with Expression Encoding—a new way to define and combine…
It is a common misconception that @ApacheParquet files are restricted to basic statistics. Footer metadata and offset-based addressing permit user-defined index structures today. Latest @ApacheDataFusio blog from Qi Zhi, Jigao Luo and myself explains how datafusion.apache.org/blog/2025/07/1…
We are so close to getting predicate pushdown turned on by default in @ApacheDataFusio . Xiangpeng Hao new blog does a great job of explaining the remaining challenge and solution blog.xiangpeng.systems/posts/parquet-…
For my last class this semester, I crammed our Advanced Database Systems course into one lecture. We cover the following databases in 60min: • Google BigQuery • @SnowflakeDB • Amazon Redshift • @YellowbrickData • @databricks • @duckdb • TabDB youtu.be/fr5lIchF6pw
Using AVX512 to make a meatgrinder for strings I love reading papers from @peterabcz Thomas Neumann and Viktor Leis The InfluxDB reading group I run is reading: FSST: Fast Random Access String Compression vldb.org/pvldb/vol13/p2…
This is partly correct. AFAIK, Codd didn't work on SEQUEL. That was Chamberlin + Boyce. Codd had his own RDBMS query lang called Alpha: dl.acm.org/doi/10.1145/17… But Codd did want to make it easy for anyone to query a DB. See 2007 quote from Codd's widow: archive.computerhistory.org/resources/acce…

For any young devs on my timeline unaware of Oege de Moor(@oegerikus)'s work this is a quick read. (Semmle was acquired by Github in 2019). His "Algebra of Programming" is the most mind expanding book on programming I ever read. hackernoon.com/founder-interv…
We were surprised to find out that everybody uses our strings. They even call them "German Strings". 😲🇩🇪 Take a look at our latest blog post to find out why @duckdb, @ApacheArrow, @DataPolars, and Facebook Velox use our custom string implementation. cedardb.com/blog/german_st…
Any chance a few folks could run the following fio command on various SSDs and tell me the latency, drive model and filesystem?
Here's what we did at @ReasonBangalore meetup yesterday. We wrote a Dream web server with a hello world route - ie. you curl and get the string “hello, world” from the “/“ endpoint. We started from scratch, empty directory even, and worked our way up. We intend to continue this…

Twenty years ago this month, abandoning electronic voting in Ireland was officially set in motion. In response to pressure from software experts, a commission was created, and the time since has only validated their recommendation to pause. Still grateful!
