The Etsy engineering team recently described how the company migrated its long-running MySQL sharding infrastructure to Vitess. The transition moved shard routing from Etsy’s internal systems to...

本文介绍了如何通过sharing-jdbc中间件实现GaussDB的读写分离，以减轻高并发场景下的服务器负载。主数据库负责写操作，从数据库负责读操作，利用数据库复制技术同步数据。配置两个jdbc-url数据源，分别连接主节点和只读备节点，以实现高效的读写分离。

MongoDB的Sharding功能可以在不同的机器上分布文档以提高性能。可以在Spring Boot中使用Sharding来操作MongoDB。

本文讨论了Sharding和Partitioning的概念、相似之处和不同之处。PostgreSQL没有原生的Sharding解决方案，但可以在应用程序级别进行分片。PostgreSQL支持复制和实例，可通过复制和添加只读副本实现水平扩展。此外，PostgreSQL还支持表分区，可将写操作分布到多个分区表中。文章还介绍了Active Record中的水平分片功能，以及如何使用多个数据库和分区表构建可扩展的应用程序。

本文讨论了PostgreSQL中的Sharding和Partitioning，介绍了不同的分片和分区概念，以及如何通过应用级Sharding和表级Partitioning来实现数据分片。还提到了PostgreSQL的水平扩展和垂直扩展技术，以及Ruby on Rails和Active Record中的Horizontal Sharding。最后，提到了一本关于高性能PostgreSQL和Rails的新书以及作者的相关博客和演讲。

本文介绍了京东物流系统中使用的分库分表中间件ShardingSphere的问题分析和解决方案。通过改造sharding-jdbc，解决了MYSQL集群架构连接数上限的问题，实现了横向扩展。文章详细介绍了sharding-jdbc的工作流程和源码分析，并给出了改造步骤。改造后的系统通过自定义分片算法实现了分库分表。文章总结了分库分表的概念和优势，并强调了在系统设计中需要权衡利弊来决策是否需要进行分库分表。
