Project Summary

A geo-distributed KV store for metadata management

Project Description

Xline is a distributed KV storage for metadata management. Xline makes it possible to manage metadata, such as indexes, permissions, and configurations across multiple clusters. Xline can achieve high-performance data access and strong consistency in cross data center scenarios. Currently, Xline is compatible with the ETCD interface, so that existing ETCD users can seamlessly switch to Xline and get high performance metadata management across multiple clusters.

The Aim of the Project

Data isolation and data fragmentation resulting from cloud barrier become impediments to business growth. The biggest challenge of multi-data center architecture is how to maintain strong data consistency and ensure high performance in the scenarios of multi-data center competition and modification. Traditional single data center solutions cannot meet the availability, performance and consistency requirements of multi-data center scenarios. DatenLord launched the open source distributed KV storage called Xline, which is targeted to multi-data center scenarios. It aims to realize a high-performance metadata management solution across multiple clusters, which is critical for businesses with geo-distributed, and multi-active deployment requirements.

Characteristics of the project

1. Accelerate data access across clouds by caching hot data in memory, and provide unified data management to automate data migration and backup.
2. It is the first geo distributed consistency management service based on the WAN consensus protocol. It addresses the challenges of convergence and consistency across clouds.
3. Unified data management for multi-cluster scenarios, making mutual access, discovery, and modification simple and convenient.
4. High stability and excellent storage performance; Provide KV interface, Multi-Version Concurrency Control and is compatible with ETCD.

Why CNCF?

The geo-distributed deployment has become increasingly popular nowadays, in which situation Xline is of help in terms of unified management of metadata with high performance and security. We believe that Xline is a missing piece of the CNCF landscape. The project is motivated by challenges observed in cloud-native environments, and will benefit users and organizations that store data in multi-clusters and across clouds. Xline is built naturally for cloud native, compatible with ETCD interface. The success of this project depends on maintaining its vendor-neutrality, as well as keeping collaboration with project adjacent in the ecosystem. Given its mission and relationship with the CNCF projects, we truly believe CNCF, as an open source platform, is a perfect place to host Xline.

We hope to acquire support (e.g., legal assistance in aspects of potential IP and trademark issues) from CNCF, and collaborate with other projects in CNCF to make geo-distributed deployment convenient. We believe the inclusion of Xline in the CNCF ecosystem could help increase the awareness of the project. With the guidance of CNCF, we can follow its procedures and standards, and set attainable goals to refine our open source tools, promote community engagement, and integrate Xline with other cloud native projects.

Benefit to the Landscape

Xline is focused on the infrastructure of cloud native storage, which is vital to the development of cloud native technology. The joining of Xline will help CNCF accelerate the evolution of cloud native storage system in terms of data access in geo-distributed scenarios, in turn benefiting the entire cloud native ecosystem.

First, Xline is fully aligned with the cloud native computing ecosystem because it is compatible with ETCD interface. ETCD enables K8S management in a single cluster, while Xline expands cloud native scenarios to multi clusters and allows users to experience task orchestration across multiple clusters by K8S. Moreover, Xline achieves metadata management among multi-clusters with high performance and security.
