    Apache...Sedona, you say? I'm lucky as ever to be able to work on the @ApacheSedona and @wherobots internals for my new position, but it doesn't mean it was easy getting started. Read on for my adventures with (Py)Spark, Sedona, and distributed spatial!

    New #gischat post! This one following up as a practical @IbisData/@duckdb powered exploration into a few of the spatial partitioning methods suggested in a recent @GeoParquet discussion. Let me know what I missed!

    First blog post in a long time! I started writing a post ~2 years ago on adventures counting 130M U.S. buildings by zipcode and finally circled back to write it up. Everybody is a winner really, but @duckdb @IbisData , @ApacheArrow, and @GeoParquet were essential throughout!

    I just realized that my talk at @SciPyConf 2024 is up! For a 30-minute tour of @ApacheArrow nanoarrow and its place in the scientific Python ecosystem check it out! - Talk: youtube.com/watch?v=EIk6bv… - Slides: dewey.dunnington.ca/slides/scipy20…

    ApacheArrow nanoarrow 0.6.0 is released! This project is one of my favourite things to work on - it's a C library with C++, R, and Python bindings that make it easier than ever before to import and export tabular data using @ApacheArrow 🧵 ⬇️
