Description
The LAS table is going away in v4.4 and being replaced by a history table. The snapshot window is currently resized based on in-memory cache pressure, which is indicated by stats around reading/writing from/to the LAS table rather than the in-memory WT cache. With MongoDB v4.4's WT, we will likely need a new solution for snapshot window resizing.
