Uwe L. Korn created ARROW-1734: ---------------------------------- Summary: C++/Python: Add cast function on Column-level Key: ARROW-1734 URL: https://issues.apache.org/jira/browse/ARROW-1734 Project: Apache Arrow Issue Type: New Feature Components: C++, Python Reporter: Uwe L. Korn Assignee: Uwe L. Korn
Add a {{Cast}} function on a column level that casts all underlying arrays. There are three possible options we could implement: * Make a special cast implementation that takes a ChunkedArray and returns a simple Array * Make a universal implementation that takes a ChunkedArray and applies a Kernel on each Array, returning a ChunkedArray with the same chunking * Make a universal implementation that takes a ChunkedArray and applies a Kernel on each Array, returning a plain Array with no chunking -- This message was sent by Atlassian JIRA (v6.4.14#64029)
