Version 2.0 Migration Timestamp/Mask #1065 Series.unique() with dtype “timedelta64[ns]” or “datetime64[ns]” now returns TimedeltaArray or DatetimeArray instead of numpy.ndarray Series.unique() with dtype “timedelta64[ns]” or “datetime64[ns]” #1039 to_datetime() and DatetimeIndex now...
Not yet, Windows is still in the works. Python 3.13.0b2 was the first version that included free-threaded support in Python itself; there is an issue with it inpyconfig.hthat needs working around before NumPy can be built. I'm working on that right now actually - it'll be a few wee...
Expressions that would result in an object dtype or involve datetime operations (because ofNaT) must be evaluated in Python space. The main reason for this behavior is to maintain backwards compatibility with versions of NumPy < 1.7. In those versions of NumPy a call tondarray.astype(str)will...

This is beneficial to Python developers who work with pandas and NumPy data. However, its usage requires some minor configuration or code changes to ensure compatibility and gain the most benefit.PyArrow is a Python binding for Apache Arrow and is installed in Databricks Runtime.

Sure. Right. We need to make a little Pandas and NumPy comparison here. So we need to go back in history a bit. Pandas originally built on top of NumPy. NumPy has not traditionally had a string data type. They do since NumPy version two, but traditionally if you wanted to store strin...
