What it does
This deprecated class synchronizes the customer grid by identifying customers who have logged in since the last grid update and triggers a reindex for those specific customers.
Developers would have used this to keep the admin customer grid up-to-date with recent customer login activity, though it's now deprecated and replaced by more modern indexing mechanisms.
