If you do not specify the dtypes, Koalas will try to be smart and infer the dtype for object columns. Rough pads on the palms and soles help it to grip tree trunks and branches, and both front and hind paws have long sharp claws. They can conceptualize something and execute it instantly. If the row count is beyond this limit, computation is done by Spark, if not, the data is sent to the driver, and computation is done by Pandas API. Pyarrow -> 0.13.0, import Pandas as pddf = pd.DataFrame({‘col1’: [1, 2], ‘col2’: [3, 4], ‘col3’: [5, 6]}) They are asocial animals, and bonding exists only between mothers and dependent offspring.
