> Whilst the previous ordering might have been surprising it is a total order that matches the equality relation, this PR is neither. Right, I agree that any order should match equality relation and there is a bug here. We will discuss with @berkaysynnada shortly. > Perhaps we might take a step back as to what you're hoping to achieve with this? Sure, thanks for offering to help. Basically the issue we are facing is the current total order results in wrong branches being taken during pruning operations in downstream use cases (like Datafusion). We are trying to arrive at a partial order that is compatible with equality, and only returns `true` when the comparison is definite. Such a consistent partial order can be safely used in branching logic. Do you have any ideas how we can achieve that? -- This is an automated message from the Apache Git Service.
