📢📢VLDB 2026 will have a ShadowPC! Apply at forms.office.com/e/XYihKj4UKq by March 1! Great opportunity for folk who are new to the data management community and want to gain experience with paper reviewing. For more info, see the application form. Chairs: @zistvan, @wangtzh , & I.
Xiangpeng Hao strikes again: Turns out you can both 1. Implement 🇩🇪 strings in Rust 2. They actually improve end to end performance in @ApacheDataFusio. It takes a lot more than a straightforward naive implementation to do so: influxdata.com/blog/faster-qu…
There are so many interesting insights in this paper. Eg, in the real world only a little less than 50% of the executed statements are read-only SELECTs, whereas in the benchmarks the SELECTs are between 75% to 80%. If you are attending VLDB’24 attend its presentation. (5/n)
Great writeup from @InfluxDB intern Xiangpeng with help from @andrewlamb1111 on "How Good is Parquet for Wide Tables (Machine Learning Workloads) Really?" Some good tests and concrete numbers in here: influxdata.com/blog/how-good-…
