-------------------------------
Summary: [Java] Improve the performance and code structure for
ApproxEqualsVisitor
Key: ARROW-6458
URL: https://issues.apache.org/jira/browse/ARROW-6458
Project: Apache Arrow
Issue Type: Improvement
Components: Java
Reporter: Liya Fan
Assignee: Liya Fan
As discussed in
https://github.com/apache/arrow/pull/5195#issuecomment-526157961, there are
some problems with the current ways of comparing floating point vectors, we
solve them in this PR:
1. there are if statements/duplicated members in ApproxEqualsVisitor, making
the code redundant and less clear.
2. the comparion of float4 and float8 are based on wrapped objects Float and
Double, which may have performance penalty.
