Pika v3.5.2 Release Highlights and Upcoming v3.5.3 Roadmap

The Pika community recently released the highly anticipated v3.5.2 version, which not only resolves historical bugs but also introduces several new features. These enhancements include Redis transaction support, a cache layer for hot‑cold data separation to boost read performance, and dynamic configuration changes for Codis‑Proxy, among others, delivering a more efficient and stable user experience.

New Features

Pika now supports Redis transactions, ensuring data consistency and reliability across a series of commands. https://github.com/OpenAtomFoundation/pika/pull/2124

A cache layer has been added on top of Pika to achieve hot‑cold data separation, improving read performance. https://github.com/OpenAtomFoundation/pika/pull/2171

Codis‑Proxy now supports dynamic modification of configuration parameters, simplifying parameter tuning. https://github.com/OpenAtomFoundation/pika/pull/2110

Complete Go test cases have been added. https://github.com/OpenAtomFoundation/pika/pull/2082

CI pipeline now includes caching to accelerate compilation. https://github.com/OpenAtomFoundation/pika/pull/2093

Added a redis‑copy traffic replication tool. https://github.com/OpenAtomFoundation/pika/pull/2060

Bug Fixes

Fixed a coredump issue when using the SETRANGE command. https://github.com/OpenAtomFoundation/pika/pull/2141
