Run all version comparison checks between two dataset snapshots

Runs CP-01 to CP-08 comparing a current delivery against the previous one.

Usage

run_comparison_checks(df_current, df_previous, config, con)

Arguments

df_current: Character. DuckDB table name for the current delivery.
df_previous: Character. DuckDB table name for the previous delivery.
config: Named list. Merged configuration as returned by load_config.
con: A DuckDB connection from DBI::dbConnect(duckdb::duckdb()).

Value

A list of dq_result objects. The list carries attributes new_cols, dropped_cols, and type_changed (character vectors) for use by the snapshot writer.
