Description
Describe what's wrong
This is a feature request to see if the support for ALP compression for Floating point numbers is better than the existing one. If yes, the adding support for ALP would be beneficial as we deal with many Float columns.
Does it reproduce on the most recent release?
No
Discussed in #60393

Came across a youtube video discussing ALP compression. It looks ALP works well for Floating point numbers compression in vectors and faster.
