Does this skill support Hibernate or Mutiny?

No, the skill specifically enforces the use of native SQL repositories and Kotlin coroutines (suspend functions) over Hibernate and Mutiny to ensure performance.

How does it handle database migrations?

It provides guidance on using Flyway migrations and writing database-agnostic SQL to support PostgreSQL, MySQL, and H2 simultaneously.

What is the benefit of the dual-channel architecture?

It separates high-throughput commands from event processing, ensuring state travels with messages while minimizing database reliance and preventing bottlenecks.

Why does this skill recommend UUID v7?

The skill enforces IDV7 (UUID v7) because they are time-sortable and globally unique, making them ideal for high-performance distributed systems.

Guides the development and maintenance of the modular Lemline runner ecosystem for serverless workflow execution.

This skill provides specialized knowledge for building and extending the Lemline runner, a high-efficiency serverless workflow DSL runtime. It offers domain-specific guidance on the modular architecture, covering everything from core messaging and configuration to feature modules like retries, forks, and schedules. It enforces critical development patterns such as Kotlin coroutines, native SQL repositories, and the outbox pattern to ensure robust, production-grade implementations within the Quarkus/Kotlin environment.

Key Features

01Modular architecture guidance for feature-focused runner modules

02Native SQL repository patterns for cross-database compatibility

03Best practices for Kotlin coroutines and non-blocking I/O

04Standardized outbox and cleaner pattern templates for reliable processing

0536 GitHub stars

06Implementation details for dual-channel messaging (commands/events)

Use Cases

01Implementing database-agnostic migrations and repository operations for high-throughput environments

02Adding new workflow capabilities like custom tasks or triggers to the Lemline ecosystem
