Data Access & Storage Patterns

When this skill applies

Use this skill when the main question is where data should live and how a VTEX IO app should read or write it.

Designing new data flows for an IO app

Deciding whether to use app settings, configuration apps, Master Data, VBase, or VTEX core APIs

Reviewing code that reads or writes large, duplicated, or critical datasets

Introducing caching layers or derived local views around existing APIs

Do not use this skill for:

detailed Master Data schema or entity modeling

app settings or configuration app schema design

auth tokens or policies such as AUTH_TOKEN, STORE_TOKEN, or manifest permissions

service runtime sizing or concurrency tuning

Decision rules
