This is a serious problem for a daily load.
A 4-hour daily job is difficult to manage because in cases of its own failures or delays in preceding jobs you can easily run out of your
loading window.
If you can't optimize index build time try to search for alternatives. Who are the end users of the table? Do all of them always require the
whole table at a time? If not, you can perhaps split the table into a few smaller tables. This might suit the bulk of your users. A small minority
might cope with doing UNIONs. You might still hear occasional protests from them but at least you place yourself in a *manageable* situation.
Regards,
Victor
