call_report.config.set_config#

call_report.config.set_config(*, dataframe_backend: Literal['pandas', 'polars', 'pyarrow'] | None = None, lazy: bool | None = None) → None[source]#

Update the current thread’s package configuration.

Only the keys explicitly passed are changed. Omitted keys keep their current value. The change is thread-local, so it never affects other threads.

Parameters:

dataframe_backend{“pandas”, “polars”, “pyarrow”}, optional: The dataframe library that readers should return native frames for.
lazybool, optional: If True, readers return a lazy frame (currently only supported for the "polars" backend, via polars.LazyFrame).

Raises:

ValueError: If dataframe_backend is not a supported backend name, or if the resulting dataframe_backend/lazy combination is unsupported (e.g. lazy=True with the "pandas" backend).

Examples

>>> set_config(dataframe_backend="polars")
>>> get_config()["dataframe_backend"]
'polars'
>>> set_config(dataframe_backend="pandas")
