Dynamic Filters for TopK and Join queries landing in DataFusion 50.0.0: datafusion.apache.org/blog/2025/09/1…
People asked me about how OpenDAL makes money: the answer is it doesn’t. OpenDAL is for public goods, it helps you to access storage services and make money 🫡
Tobias Schmidt (TUM) at @VLDBconf presented SQLStorm, which uses LLMs to generate a huge amount of large queries. SQLStorm now has 18K different complex queries and runs on a large real-world dataset (stackoverflow) paper: vldb.org/pvldb/vol18/p4… code: github.com/SQL-Storm/SQLS…
Recording of "Introduction to Variant in @ApacheParquet ": youtube.com/watch?v=nlOJD7… Here are the slides: docs.google.com/presentation/d…
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…
