2, newest firstParquet writer: DELTA_BINARY_PACKED on INT32 columns emits 33-bit miniblocks, files unreadable by pyarrow and arrow-rs### What happens? When DuckDB writes an `INTEGER` (or `UINTEGER`) column with `DELTA_BINARY_PACKED` (`PARQUET_VERSION V2`, once the dictionary is abandoned), it computes the deltas in 64 bits. Two consecutive values more than 2^31 apart then produce a miniblock with bit width...duckdb/duckdb · hanke580Open ↗[RFC] GPU Offload of Query Plan Subtrees to Sirius## Motivation Sirius [1] is a GPU execution engine that plugs into a database. The host hands it a query plan in Substrait [2], an open format for exchanging plans between engines, and Sirius executes it on GPU with NVIDIA's cuDF/RMM libraries. Plugged into DuckDB, it was...ClickHouse/ClickHouse · rienath5 reactionsOpen ↗
