Config Assistant & Cloud Costs

Smart Configuration Assistant

Quarkus configuration relies heavily on application.properties and application.yaml. Quarkus Studio supercharges these files with live extension catalog sync, profile intelligence, diagnostic safety checks, and real-time cloud cost estimations.

☁️ Live `code.quarkus.io` Catalog Sync

Quarkus Studio connects directly with the code.quarkus.io metadata API to keep configuration schemas completely up to date.

Offline Cache: Pre-bundled with rich property documentation for core extensions (RESTEasy Reactive, Hibernate ORM, Agroal, Kafka, Redis, Security, OpenID Connect).
Dependency Awareness: Inspects your active pom.xml or build.gradle to prioritize autocompletion keys for installed libraries.
Command: Run Quarkus Studio: Reload Config Metadata to refresh metadata anytime.

🎯 Profile-Aware Completion & Value Suggestions

Seamless autocompletion for Quarkus environment profile prefixes:

%dev. (Development mode)
%test. (Continuous and unit testing)
%prod. (Production deployment)
Custom profile prefixes (e.g. %staging.)

After entering =, intelligent enum suggestions pop up (e.g., fast-jar, native, postgresql, mysql, true, false).

⚠️ Build-Time Fixed Property Diagnostics

In Quarkus, certain configuration properties are fixed at build-time (for example: quarkus.package.type, quarkus.datasource.db-kind, quarkus.hibernate-orm.database.generation). Attempting to override them with a runtime environment profile like %prod. will produce runtime errors or be silently ignored.

Quarkus Studio identifies these invalid overrides directly in the editor:

Surfaces clear Diagnostic Warnings on misconfigured keys.
Provides a one-click Quick Fix action: Remove '%prod.' prefix to safely set the property globally at build time.

💡 Inline Cloud Cost & Resource Estimates

Quarkus Studio calculates estimated memory consumption, cold start times, and serverless compute costs directly in your editor via Inlay Hints:

quarkus.package.type=native       # 💡 [Cloud Est: ~32MB RSS | Cold start <25ms | Lambda: ~$0.25/1M]
quarkus.package.type=fast-jar     # 💡 [Cloud Est: ~192MB RSS | Cold start ~1.5s | Lambda: ~$0.83/1M]
quarkus.virtual-threads.enabled=true  # 💡 [Loom: ~90% lower thread memory per req]
quarkus.datasource.jdbc.max-size=25   # 💡 [Pool Buffer: ~50MB RAM | 25 conns]
