Product and content updates are listed when behavior, public guidance, datasets, or review boundaries materially change. Dates are not refreshed only to make unchanged pages look new.
Added five connected database tables and six tested lessons for query regressions, connection pools, lock waits, replication lag, migrations, and customer impact. Every result remains synthetic, downloadable, and executable in the browser or DuckDB.
Expanded the connected SQL Lab to 10 tables, 10,898 deterministic rows, and 12 tested lessons; added six dashboard examples with complete SQL and eight field-level event contracts with privacy guidance.
Published a six-table synthetic SaaS dataset with nine read-only lessons, indexable lesson pages, browser execution, DuckDB seed SQL, JSON, table-level CSV downloads, and declared provenance.
Split the first production journey into focused steps for sending an event, verifying schema and ingestion, writing SQL, creating a dashboard and alert, and reviewing rollout safety.
Expanded the public cookbook to 80 read-only DataFusion recipes with typed schemas, deterministic fixtures, result tables, visualizations, edge cases, JSON and CSV downloads, and dashboard or alert guidance.
Brought product documentation onto telemetry.sh with canonical metadata, structured navigation, sitemap coverage, and permanent mappings for known legacy documentation paths.
