uhashring Consistent Hashing Library

uhashring is a full-featured pure Python library for consistent hashing, primarily used in distributed systems, caches, and databases to efficiently distribute data across nodes. It aims to prevent total reshuffling of key-node mappings when nodes are added or removed. The library offers Ketama compatibility, customizable hash and weight functions, and supports instance-oriented usage. The current version is 2.4, with releases occurring periodically, as evidenced by its PyPI update in April 2025 and ongoing GitHub activity. [1, 2]
