Building an index can consume I/O, hold locks, or increase write latency depending on the database and operation. A migration that works on a small staging dataset can disrupt a larger production workload.
Check database engine and version, supported online index options, table size, write rate, replication lag, disk headroom, and migration duration. Test with representative data and monitor lock behavior.
Use the database’s supported low-impact method and a monitored rollout. Define stop thresholds for latency and replication, and verify the index is used before removing any old structure.
