We have several process, where we want to bulk update a single value, such as changing all email addresses on a prod/dev data refresh or flipping a 'sent' flag to Y. Currently, we're doing this with a microflow that loops through all our Accounts (about 75k) and makes the update, using offsets and committing every 1000 records.
Running the update on email addresses takes almost 4 minutes for each 1000 and runs 4-5 hours on whole. Are there other ways to do mass data updates that don't require looping through in a microflow? Ultimately we just want to - - update Account set EmailAddress = 'testemail';
