Table.to_arrow

Table.to_arrow() → pyarrow.Table

Return this table as a pyarrow.Table.

Each row array becomes a column with the same name and dtype.

Requires pyarrow.

Returns:

pyarrow.Table

This table represented as an Arrow Table.

Notes

1D contiguous numeric columns wrap the underlying VTK buffer zero-copy. Booleans, complex numbers, and strings go through pyvista’s existing VTK conversion and are copied. Arrow buffers are immutable by contract, so consumers cannot mutate VTK memory through the returned table.

>>> import numpy as np
>>> import pyvista as pv
>>> table = pv.Table({'a': np.arange(3), 'b': np.array([0.5, 1.5, 2.5])})
>>> table.to_arrow().schema.names
['a', 'b']
