mlr3db 0.5.1

• Compatibility with new duckdb version (#36).

mlr3db 0.5.0

• New converter as_duckdb_backend().

mlr3db 0.4.2

• Compatibility fixes with new duckdb version.

mlr3db 0.4.1

• Temporarily disabled some tests to overcome some regressions in duckdb.

mlr3db 0.4.0

• Added a show_query() method for DataBackendDplyr (#4).
• A reconnector is automatically added in as_data_backend() for objects of type tbl_SQLiteConnection and tbl_duckdb_connection.

mlr3db 0.3.0

• New backend DataBackendDuckDB.
• dplyr is now optional (moved from imports to suggests).

mlr3db 0.2.0

• Set a primary key for SQLite databases generated from data frames.
• Set a reconnector for SQLite databases generated from data frames.
• Resolved a warning signaled by dplyr-1.0.0.

mlr3db 0.1.5

• as_data_backend() method to construct a DataBackendDplyr now specialized to operate on objects of type "tbl_lazy" (was "tbl" before). This way, local "tbl" objects such as tibbles are converted to a DataBackendDataTable by mlr3::as_data_backend.data.frame().

mlr3db 0.1.4

• Connections can now be automatically re-connected via a user-provided function.
• DataBackendDplyr now has a finalizer which automatically disconnects the database connection during garbage collection.

mlr3db 0.1.3

• During construction of DataBackendDplyr, you can now select columns to be converted from string to factor. This simplifies the work with SQL databases which do not naturally support factors (or where the level information is lost in the transaction).

mlr3db 0.1.2

• Fixed $distinct() to not return missing values per default.
• Added na_rm argument to $distinct().
• Renamed as_sqlite() to as_sqlite_backend()

mlr3db 0.1.1

• Initial release.
