For your usecase and upgrade: don't add the updateLog to your configs, and don't add autocommit to your configs, and things should work fine. if you decide you wnat to start using something that requires the updateLog, you should probably add a short autoCommit with openSearcher=false.
Thank you for your answer. Using updateLog seems to have another downside -- a huge hit to performance. It wouldn't be terrible on incremental updates. These happen once a minute and normally complete extremely quickly - less than a second, followed by a commit that may take 2-3 seconds. If it took 5-10 seconds instead of 3, that's not too bad. But when you are expecting a process to take three hours and it actually takes 8-10 hours, it's another story.
