CostBench is an open‑source benchmark that evaluates cloud data warehouses on performance‑per‑dollar rather than raw speed. It measures both read‑side query efficiency and, in early stages, the cost of ingesting fresh data, helping teams pick platforms that deliver the most analytical performance for their budget.
Halodoc built an Airflow‑native, config‑driven data profiling framework that replaces ad‑hoc SQL checks across hundreds of tables. It delivers column‑level statistics, join intelligence, and source‑table analysis, giving analysts and engineers a unified view of data quality and lineage. The system automates profiling, improves trust, and reduces engineering bottlenecks.
Iceberg 1.11 adds a registerView primitive that lets catalogs point to existing view metadata without recreating the view, preserving schema and version history. This mirrors the existing registerTable feature, closing a gap in catalog migrations and simplifying data lake management.
