这种方法称为分片(sharding),它将数据跨多个数据库进行分区(shards),因此它类似于表分区,但规模更大,复杂性更高。如果你要为这家社交媒体公司使用这种策略,那么你可能会决定采用100个独立数据库,每个数据库承载大约1000万用户的数据。 分片是一个复杂的主题,由于这是一本介绍性的书,因此我不会详细讨论它。以下是分片需要解决的几

Scaling in SQL Server can be easily achieved through sharding. PostgreSQL vs. MSSQL – Table Statements Truncate In PostgreSQL, TRUNCATE removes all rows from a set of tables. It is faster than DELETE because it does not scan the tables first, and disk space is reclaimed immediately withou...
Server-side scripts no Transact SQL, .NET languages, R, Python and (with SQL Server 2019) Java no Triggers no yes yes Partitioning methods none tables can be distributed across several files (horizontal partitioning); sharding through federation none Replication methods none yes, but depending...
Distributed SQL databases are built from the ground-up, while NewSQL databases tend to add synchronous replication and sharding technologies to existing client-server relational databases like PostgreSQL. However, both achieve most of the same goals. ...
Summary: Table-based partitioning features in SQL Server 2005 provide flexibility and performance to simplify the creation and maintenance of partitioned tables. Trace the progression of capabilities from logically and manually partitioning tables to the latest partitioning features, and find out why, whe...
Supports vertical and horizontal scaling, with features like partitioning, sharding, and replication for distributed environments Looking for the most efficient way to get started? Whether you are looking for cost savings, lower management overhead, or open source, InfluxDB can help. ...
This approach can be expensive and may lead to performance issues if the server is overloaded. Some SQL databases can also be scaled horizontally, but it can be challenging due to their single-server architecture. Developers and data engineers can use sharding, partitioning, replication, and cluste...
the case that there is an application using a single database server, it can be converted to sharded cluster with very few changes to the original application code because the way sharding is done by MongoDB. oftware is almost completely decoupled from the public APIs exposed to the client ...
