Can I use this skill if I don't have PostgreSQL?

Yes, while PostgreSQL is the default, the skill fully supports Redis-based locking as a valid implementation per the RFC-44 specification.

What is RFC-44 in the context of this skill?

RFC-44 is the architectural standard for Bitso services that defines specific implementation patterns and best practices for distributed locking to ensure consistency across Java applications.

Does this skill help with Spring @Scheduled jobs?

Absolutely. It provides specific patterns to wrap scheduled tasks in distributed locks, ensuring that only one instance of a job runs across your entire cluster.

How does it handle resource cleanup?

The skill promotes the use of the Try-with-resources pattern in Java, which ensures that locks are automatically released even if an exception occurs during execution.

Is it compatible with functional programming in Java?

Yes, it includes specific implementation examples for the Vavr library, allowing you to use distributed locking within functional pipelines.

클라우드 인프라

Implements RFC-44 compliant distributed locking patterns for Java services using PostgreSQL or Redis.

소개

This skill provides a standardized framework for managing distributed locking in Java microservices, adhering strictly to RFC-44 specifications. It enables developers to coordinate shared resource access across multiple service instances using either PostgreSQL advisory locks or Redis-based implementations. The skill includes comprehensive migration workflows for transitioning from legacy systems like Fabric8 leader election, offering production-ready patterns for scheduled jobs and complex concurrency scenarios to ensure data integrity and system stability.
