We ran into this around push notifications when the cache went cold. We needed a lock so two workers would not process the same job. One option expired itself. The other lived next to our source of truth. Failover behavior mattered more than the benchmark. We started with the store we could operate, then moved the hot path later. Pick the tool your on-call can reason about.

We extracted one high-churn billing endpoint behind a strangler facade. Dual-writes ran for two weeks while we compared totals nightly. A feature flag controlled read traffic so we could roll back instantly. The hardest part was matching edge-case rounding in legacy invoices. Cutover finished with no customer-facing downtime and a smaller blast radius. We kept the facade until three more endpoints followed the same path.
