The changes eliminate state bleeding across concurrent DuckDB readers, standardize dependencies for educational execution scripts, and enforce uniform formatting rules across project documentation.</p>https://wintermutecore.com/posts/duckdb-wal-group-commit-and-art-batch-scan/Wed, 16 Sep 2026 14:00:00 +0000https://wintermutecore.com/posts/duckdb-wal-group-commit-and-art-batch-scan/<p><a href="https://github.com/duckdb/duckdb">DuckDB</a> took 221 commits on main in the last seven days, shortly after the 2.0 branch was merged back into it. Two changes affect how DuckDB behaves as an embedded store behind a pipeline. Concurrent commits now share WAL fsyncs, and <code>IN</code> list lookups on ART indexes run as one batch. The rest is profiler metrics, an optimizer guard, and compatibility work for extensions built on the old C API.</p>https://wintermutecore.com/posts/duckdb-parquet-encoding-stats-aggregate-guards/Mon, 24 Aug 2026 14:00:19 +0000https://wintermutecore.com/posts/duckdb-parquet-encoding-stats-aggregate-guards/<p>DuckDB is an embedded analytical database used as a local query engine and as a Parquet writer in ETL pipelines. The <a href="https://github.com/duckdb/duckdb">DuckDB</a> main branch took 213 commits in this window. The operator visible thread is a Parquet footer field that lake readers already expect, plus two aggregate correctness guards.</p>
