Client Stories
Notes from teams who hired Service Riverbase for database refactoring and query performance work.
“The query review caught a join we had been patching with caches. Once the covering index landed, the checkout timeout alerts dropped within a day. I still wish we had booked the assessment a quarter earlier—we spent too long arguing about whether the schema was ‘fine.’”
“During the refactor engagement they refused to merge our ‘temporary’ columns into the permanent model. That friction saved us a second rewrite six months later.”
“The schema assessment was shorter than I expected and more opinionated than a typical audit. It gave finance a number and gave us a priority order we could defend.”
Extended story: catalog lookup after a merger
A regional retailer inherited two product catalogs after acquiring a smaller brand. Lookups at checkout joined both catalogs plus a promotions table that still used string matching on SKU codes. Service Riverbase mapped the hot path, introduced a read-model table refreshed by a nightly job for the first phase, and only then proposed renaming the surviving catalog tables. Cutover happened on a Sunday evening with a documented rollback that was never needed. The client kept the migration notes in their runbook and later reused the same staging checklist for a warehouse schema change without our involvement.
