PartiQL Lang Kotlin (PLK) 1.0

PartiQL Lang Kotlin (PLK) is an open-source project that provides foundational JVM libraries (written in Kotlin) related to the syntax, semantics, and execution of the PartiQL Language.

Since its inception as a proof-of-concept in 2016, PartiQL has evolved from an experimental query language to a robust, production-ready solution powering multiple systems and services across Amazon. Our journey has been marked by extensive community feedback, with hundreds of feature requests driving continuous improvement and innovation.

With PartiQL 1.0.0, we’re proud to introduce a release that addresses key technical challenges and provides a solid foundation for future development. This milestone release features significant architectural enhancements, including a plan-based evaluator, an extendable compiler, a comprehensive error handling framework, and deep correctness improvements.

Recognizing the critical importance of stability for our users, we’ve carefully curated a minimal, forward-compatible API set that will make integration and upgrades hassle-free. Our goal is to provide a query language that not only meets current needs but can adapt to future requirements without disrupting existing implementations.

Onboarding to PLK 1.0 will provide you with the latest features, bug fixes, and security patches. Our roadmap is filled with exciting developments, including common table expressions, advanced algebraic optimizations, and expanded query capabilities that our community has been eagerly anticipating.

We recognize that no software release, including 1.0.0, is without flaws. Software evolution is a continuous journey, and we embrace this reality with a transparent and pragmatic approach to versioning and improvement.

Our commitment means:

With each release, our goal remains consistent: deliver a robust, forward-looking query language that meets the complex needs of our diverse user base. We will continue to prioritize backward compatibility, provide clear migration paths, and maintain transparent communication with our community. Your feedback is not just welcome—it’s essential to our ongoing development.
