mlr3db 0.5.0
- Support for parquet files as Backend via DuckDB.
- 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()
