Ji Liu created ARROW-6250:
-----------------------------
Summary: [Java] Implement ApproxEqualsVisitor comparing approx for
floating point
Key: ARROW-6250
URL: https://issues.apache.org/jira/browse/ARROW-6250
Project: Apache Arrow
Issue Type: New Feature
Components: Java
Reporter: Ji Liu
Assignee: Ji Liu
Currently we already implemented {{RangeEqualsVisitor/VectorEqualsVisitor}} for
comparing range/vector.
And ARROW-6211 is created to make {{ValueVector}} work with generic visitor.
We should also implement {{ApproxEqualsVisitor}} to compare floating point just
like cpp does
