Should update-table still return a promise?

[ricardojmendez]

Given that:

• We can only do one update at a time
• We no longer need to do multiple updates for stepping after 1640651

Do we still need update-table to return a promise? Doesn't it make more sense to make it a blocking call, since we don't want to execute multiple updates while one is already running?

Although (thinking out loud) if the update operation takes a while, we wouldn't want to block the thread for the duration...

Nevermind, the operations can take a while and we could continue adding items meanwhile, just not updating the table.
