Hi all We would like to propose Kvrocks [1] as a new apache incubator project, you can find the proposal [2] of Kvrocks for more detail.
Kvrocks is a distributed key-value NoSQL database, supporting the rich data structure and be widely used by many internet business for example, the recommendation service can use hashes to store user characteristics and the sorted set to sort them. For supporting more users, Kvrocks also have good integration and ecosystem compatibility with other NoSQL database API and script. In comparison to current open source NoSQL database like Redis, which also has rich data structure, Kvrocks data be stored in disk storage, but the redis data be stored in memory, it means the cost is higher and the capacity is limited when compare to disk storage solution, this is why we created Kvrocks project to solve the cost and capacity issues by using disk storage solution, the following are key features of Kvrocks: - Compatibly support Redis protocol and data structures (String/List/Hash/Set/Sorted-set/Bitmap/GEO/Sorted-Int) - Disk-Based, all data and updates always persist on the disk - Proxyless centralized cluster - Stored procedures based on Lua script - Transaction(no strict ACID) - Publish-Subscribe - Tunable consistency(In-Progress) Kvrocks was designed to decrease the cost of memory and increase the capacity while compared to Redis. Also, Kvrocks aims to become a distributed multi-model NoSQL database in the future. We will provide more features to expand its usage scenarios but all data structures on disk. Kvrocks is fully compatible with Redis in term of protocol. We believe that the Kvrocks project will provide the diversity value for community if Kvrocks is introduced into the Apache incubator. I will help this project as champion and many thanks to 4 mentors : Jean-Baptiste Onofre [jbono...@apache.org], Xiaoqiao He [hexiaoq...@apache.org], Xun Liu[ liu...@apache.org], Von Gosling[vongosl...@apache.org].
