In previous articles I showed patterns for working with large amounts of data on big tables while keeping locking at a minimum. These processes can allow migrations and maintenance without requiring downtime but, in environments with unpredictable database workloads, there is a risk of heavy traffic starting at any time and disrupting a once smooth operation.
