Replication - This is one of the Interview Question

There is an update statement that affects 1 Million rows on the publisher which generates 1 Million records in transaction log. Due to this large transaction we are getting Log Reader Agent timeouts. How to handle these kinds of large transactions when replication configured?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I've encountered this scenario once, one developer ran a single update statement to update 22 Million records in a single shot.
We had issues with Log Reader agent and then devised the below approach which works without any issues.

We can handle it by updating 1 Million rows in batches of 1000/5000 so that the records get picked up by Log Reader agent to Distribution agent and then subsequently to Subscriber database as well without any issues.
