| Any comments or suggestions are welcome (besides dropping USIs for maintenance) | |
I understand that dropping of USIs for the period of maintenance is the only practical option here. Will be glad to stand corrected.
ML deletes are fast but USI is a problem there as well.
If you drop the USI, delete using ML and rebuild the USI, you might still get a reasonable timing, though, even on the DEV machine.
Liked you metaphoric description of USI - spot on!
Regards,
Victor
