Geo lookup on the Software Lifecycle Cloud

Geo lookup on KERNSTACK resolves places from a dataset you own: places load into a table with a declared text index over names and aliases, a function answers lookups keyed to that index, and coordinate-bearing results cache in the same table. The honest shape of the pattern: it serves lookup over a bounded place dataset — your delivery zones, your venues, your service areas — not a planetary maps service.

The engineering bottleneck with assembled stacks

Apps resolve places through a maps vendor on every keystroke because the dataset they actually care about is small: the cities they deliver to, the venues they list, the regions they operate in. The vendor call adds latency, per-request pricing that scales with typing, and a dependency whose outage becomes your search box’s outage — for data that would fit in a spreadsheet.

Architecture on the Software Lifecycle Cloud

The place dataset — id, names in the languages you serve, aliases and misspellings you have learned, coordinates — loads into a table, and a text index is declared over the name fields for ranked, prefix-friendly matching. The function normalises the query, checks the result cache for hot lookups, and falls back to the index. Cache entries are rows, so a place that gains a new local name teaches the system once, permanently.

Aliases are the actual product

Place lookup quality lives in the alias column: München, Munich, Minga; the airport code; the neighbourhood name locals use and gazetteers omit. Because the dataset is yours, every support ticket that ends “customers call it X” becomes a row edit that improves every future lookup — a compounding asset a vendor’s global dataset cannot build for you.

  • Lookups run at keyed-read speed on your data — no per-keystroke vendor invoice
  • Misspellings and local names accumulate as aliases in your own table
  • Offline or vendor-free by construction: the dataset and the index live in your zone

The boundary is the planet

Global address autocomplete, routing, and live geocoding belong to maps vendors; this pattern does not pretend to replace them. It replaces the vendor where the honest dataset is bounded and owned — and teams are routinely surprised how many of their “maps” features are exactly that.

FAQ

Frequently asked questions

Thousands to a few hundred thousand places comfortably: delivery areas, venue catalogues, branch networks, service regions. If a user can name the universe of things they might look up, it fits; open-ended global address search stays with a maps vendor.

They are fields on the place rows, returned with the match so clients can map, distance-sort, or bound results. Distances are computed in the function — ordinary arithmetic over owned data.

Yes. Names per language are fields feeding the same text index, and aliases cover transliterations and local forms. The multilingual reality of place names is data work, and the table is where it accumulates.

The fog between “the carrier says” and “our system says” is where this architecture earns its keep.Use Case · ProductExperiment assignmentAssignment is a pure function of the subject key and the experiment’s salt — stable across requests, no coordination needed. The function records the assignment row once and serves the variant; outcome handlers were already writing events, which now simply carry the experiment id the assignment returned. Analysis reads assignments and outcomes from neighbouring tables with the same keys.Use Case · AgenciesAgency client deliveryThe studio’s delivery shape is a template stack.json: gateway, functions or workers in the client’s stack languages, tables, buckets, and apps under one target per client, on European infrastructure the studio can name in the pitch. Previews run the same declaration; the client’s approval happens in the bound conversation with a live link. Every client’s meter is separate by construction — the studio sees delivery cost per client without allocation spreadsheets.
