Which issue does this PR close?

Closes #.

Rationale for this change

What changes are included in this PR?

As discussed in the #13748, implementation of the collapse might be one of the reasons of the slow performance when column number is very large. This PR changes the collapse implementation to remove quadratic complexity.

I couldn't verify, however updated implementation might remedy some part of the problem.

Are these changes tested?

Are there any user-facing changes?

Sorry @alamb I think I messed the PR. This should be the correct PR. I chose the target branch wrong in the previous PR.
