探索大数据处理的新边界 - 昆仑分布式数据库(KunlunBase)

kunlun KunlunBase is a distributed relational database management system(RDBMS) with complete NewSQL capabilities and robust transaction ACID guarantees and is compatible with standard SQL. Applications which used PostgreSQL or MySQL can work with KunlunBase as-is without any code change or rebuild because KunlunBase supports both PostgreSQL and MySQL connection protocols and DML SQL grammars. MySQL DBAs can quickly work on a KunlunBase cluster because we use MySQL as storage nodes of KunlunBase. KunlunBase can elastically scale out as needed, and guarantees transaction ACID under error conditions, and KunlunBase fully passes TPC-C, TPC-H and TPC-DS test suites, so it not only support OLTP workloads but also OLAP workloads. Application developers can use KunlunBase to build IT systems that handles terabytes of data, without any effort on their part to implement data sharding, distributed transaction processing, distributed query processing, crash safety, high availability, strong consistency, horizontal scalability. All these powerful features are provided by KunlunBase. KunlunBase supports powerful and user friendly cluster management, monitor and provision features, can be readily used as DBaaS. 项目地址: https://gitcode.com/gh_mirrors/ku/kunlun

在大数据洪流的时代，面对TB乃至PB级别的数据处理需求，一款既能承载巨量数据，又兼具高效率、高可用性的数据库系统显得尤为重要。**昆仑分布式数据库（KunlunBase）**正是为此而生，它融合了NewSQL的优势，力图让复杂的数据管理变得简单，为企业级应用打开了一扇全新的大门。

项目介绍

KunlunBase，一个面向未来的分布式关系型数据库系统，旨在解决现代应用程序面临的海量数据处理难题。它继承了传统数据库的事务完整性和SQL灵活性，同时克服了扩展性瓶颈，允许开发者如同操作单机数据库一样轻松驾驭大规模数据。

项目技术分析

KunlunBase基于成熟的技术栈，如PostgreSQL-11.5进行深度定制，特别增强了分布式事务处理和自动数据分片等功能。它采用独特的架构设计，将kunlun-server、存储集群（storage shard）、以及元数据集群紧密集成，确保数据的高效分布和高度一致性。通过模块化的代码结构，KunlunBase紧跟PostgreSQL的版本迭代，保持了技术的前沿性与稳定性。

应用场景

无论是在线交易处理（OLTP）还是在线分析处理（OLAP），KunlunBase都能胜任。适合于大数据仓库、实时数据分析、大规模电子商务平台、社交网络分析等多种场景。它的高吞吐量和低延迟特性能有效支撑高频交易，而自动扩展能力和高可用性则确保了金融、电商、物流等领域对数据安全与稳定性的严格要求。

项目特点

高可扩展性

• 易于水平扩展，增加服务器即可提升性能和容量，无需复杂的数据迁移。
• 支持OLTP与OLAP分离，提高处理特定类型查询的效率。

高可用性

• 即使部分节点故障，也能保证服务不间断，利用冗余机制保障数据安全性。
• 自动故障转移，保障事务的ACID属性，即使面对极端情况也保持数据一致性和完整性。

分布式事务处理

• 基于两阶段提交的分布式事务，确保跨多个节点的事务一致性，尤其通过kunlun-storage实现了“XA resilient”，弥补了社区版MySQL的不足。

SQL兼容性与优化

• 提供与PostgreSQL相同的SQL兼容性，无缝对接现有工具和ORM框架，如Hibernate、MyBatis，极大简化了应用开发流程。
• 优化的分布式查询处理，智能决策网络传输与本地计算的平衡，提升了查询效率。

自动DDL与运维友好

• 自动化处理数据库模式变化，减少了手动干预的错误风险，提高了数据库管理员的工作效率。

KunlunBase以深厚的技术积累，打造了一个既强大又易于使用的分布式数据库解决方案，降低了开发和维护高并发、大数据量应用的门槛。对于追求极致性能、高可用性和扩展性的开发者而言，KunlunBase无疑是一把开启未来数据库世界的钥匙。想深入了解或加入这场数据处理革命？立即访问官方网站或参与开源社区，一起探索更广阔的数据处理天地。
