📢 Python-Blosc2 4.13.1 is out! Continuing our "not an island" mood: stream remote datasets (HDF5, Zarr, B2Z) over HTTP/S3 lazily, and compute across formats in one expression: b2z + zarr * h5! Plus tiered caching & Win ARM64 wheels. github.com/Blosc/python... Compress Better, Compute Bigger 🚀

🚀 New Blosc post: one selective query, 24.3M taxi trips, five tools. ⚡ Cold: CTable/.b2z ~1.9x faster than DuckDB, 9.4x vs pandas 🎯 Block indexes skip ~90% of the data 🤝 Warm: dead heat with DuckDB 💾 Only +2% disk vs Parquet blosc.org/posts/ctable... #Python #DuckDB
