What vtex-io-application-performance does

This skill covers application-level performance patterns for VTEX IO services. It helps choose between an in-process LRU and VBase, refresh stale values in the background, load AppSettings at startup or on a TTL, and run independent client calls concurrently. Payment responses and live transaction state must stay out of caches.

It also addresses outbound timeouts, passing ctx.clients.vbase into client helpers, and request-level deduplication with ctx.state. Include account and workspace in in-memory cache keys when one pod serves multiple tenants, or their data can collide. This skill does not cover public-path choices or CDN Cache-Control settings.

What it helps with

  • choose between LRU and VBase for cached data
  • load AppSettings without fetching them on every request
  • run independent client calls concurrently
  • remove duplicate calls in a resolver chain
  • set timeouts for outbound requests

Example prompts for the agent

  • Review this VTEX IO service for repeated client calls and suggest where ctx.state fits.
  • Find independent calls in this resolver that can run concurrently.
  • Compare LRU and VBase for these values, accounting for account and workspace in cache keys.

What does vtex-io-application-performance do?

It guides performance and resilience work on VTEX IO Node and .NET services, with advice on caching, parallel calls, configuration loading, and request deduplication.
