水平伸缩(Horizontal Scaling):通过增加多台服务器来分担负载,从而提升数据库性能。 垂直伸缩 垂直伸缩通常较为简单,只需要升级服务器硬件。以下是一个示例 SQL 脚本,用于查看当前 SQL Server 的性能指标: SELECTSERVERPROPERTY('MachineName')AS'Server Name',SERVERPROPERTY('InstanceName')AS'Instance Name',SERVERPRO...
在Portworx存储集群上的Kubernetes里运行SQL Server容器,类似在跨多个可用性区域的Storage Spaces Direct 集群(https://docs.microsoft.com/en-us/windows-server/storage/storage-spaces/storage-spaces-direct-overview)上运行SQL Server Always On FCI。这样Recovery Point Objective (RPO)是零,而且Recovery Time Objectiv...

While it is still possible to manually configure and adjust many of the sp_configure options that were available in previous versions of SQL Server, it is recommended that database administrators allow SQL Server to automatically configure and tune all sp_configure options that SQL Server provides ...
“A globally distributed relational database service that lets customers have their cake and eat it too:ACIDtransactions and SQL semantics, without giving up horizontal scaling and high availability.” As per Google, Cloud Spanner is a No-Compromise Relational Database Service and it is the first...

NoSQL databases are often faster for certain operations because they use flexible, schema-less data models and can handle unstructured data efficiently. They are optimized for horizontal scaling, making them suitable for high-performance, distributed applications. ...
