Research direction

The issue names no files or tests. Start by locating the internal instanceof checks for Arrow tables and the existing public table APIs, then review how multiple Arrow versions are detected or warned about. Done means a version-independent table check is available and the differing-version warning behavior is covered by tests.

Written by the indexing model from the issue text.

Description

Type: enhancement
Describe the enhancement requested

Internally we check whether an object is an arrow table with instanceof which doesn't work if the table was created from another version of the library. This comes up quite often (e.g. https://github.com/vega/vega-loader-arrow/issues/350) so I propose adding a method to check such as arrow.isTable that works across arrow versions. The method should throw a warning when the table was created from a different arrow version (indicating multiple copies).
