mlr3db: Data Base Backend for 'mlr3'

Description

Extends the 'mlr3' package with a backend to transparently work with databases such as 'SQLite', 'DuckDB', 'MySQL', 'MariaDB', or 'PostgreSQL'. The package provides three additional backends: 'DataBackendDplyr' relies on the abstraction of package 'dbplyr' to interact with most DBMS. 'DataBackendDuckDB' operates on 'DuckDB' data bases and also on Apache Parquet files. 'DataBackendPolars' operates on 'Polars' data frames.

Options

• mlr3db.sqlite_dir: Default directory to store SQLite databases constructed with as_sqlite_backend()..

• mlr3db.sqlite_dir: Default directory to store DuckDB databases constructed with as_duckdb_backend()..
