swat.cas.table.CASTable.sort_values

CASTable.sort_values(by, axis=0, ascending=True, inplace=False, kind='quicksort', na_position='last')

Specify sort parameters for data in a CAS table

Parameters:

by : string or list-of-strings

The name or names of columns to sort by.

axis : int, optional

Not implemented.

ascending : boolean or list-of-booleans, optional

Sort ascending or descending. Specify a list of booleanss if sort orders are not all one type.

inplace : boolean, optional

If True, the sort order is embedded into the CASTable instance. If False, a new CASTable is returned with the sort parameters embedded.

kind : string, optional

Not implemented.

na_position : string, optional

Not implemented.

CASTable

Notes

Since CAS tables can be distributed across a grid of machines the order that they are stored in is not guaranteed. A sort order is required to retrieve data in a predictable order.
