BigQuery Utils
Useful scripts, udfs, views, and other utilities for migration
...The repository is especially useful for organizations that need practical building blocks for migration from other database systems, since it includes compatibility-oriented utilities and migration-focused UDFs that mimic behavior from platforms such as Oracle, Redshift, and Netezza. It also supports day-to-day operational work by offering optimization scripts, billing queries, performance testing examples, and dashboards built on INFORMATION_SCHEMA metadata so teams can better understand slot usage, reservations, job execution, and errors.
