I currently have availability for Rust coaching, adoption, or development; from a single call to ongoing 3 days/week. I can help your team get things done, adopt Rust and use it more effectively, or to accurately evaluate Rust as a new technology.

Just a reminder: age verification is a *bad* idea, not a good idea with implementation problems. The trouble with it is inherent, not practical.

great, can't wait to see the updates reflected in the spec. in the meanwhile, I noticed that my ducklake extension has been setting v0.2 for at least two weeks, is this expected? I installed it via the normal way using a duckdb installed via homebrew.

This week has been about SQL t-strings in Python, a message queue for Rust, a data pipeline tool and a SQL parser and translator for Python.

📢 DuckLake 0.2 is out! We added new features to the specification and improved support in the DuckDB ducklake extension.

Is the spec for v0.2 up to date? e.g. ducklake.select/docs/stable/... defines two columns but the ducklake extension has 4 (key, value, scope, scope_id). Similar issue found for ducklake_schema

ducklake_metadata

ducklake.select

Arnau Siches @arnausiches.bsky.social · Jun 24

@duckdb.org is there a decision log that can help trace the decisions that led to #ducklake v0.2? The spec would greatly benefit from having some rationale for why tables are the way they are
