以下JSON 文件描述了 Trino 分片 SQL 连接器的配置。 其结构由以下项构成:tables:对象数组,每个对象表示数据库中的一个表。 每个表对象都包含: schema:表的架构名称,对应 SQL Server 中的数据库。 名称:表的名称。 sharding_schema:与表关联的分片架构的名称,充当对后续步骤中所述的 sharding_schema 的引用。
Migrating Database Schema from SQL Server or SQL Azure to SQL Azure Federation If you have an existing database that wasn’t designed with sharding in mind, you’ll probably need to make some major architectural modifications to both your database and your application before you can think of ...

This new cross-database querying capability complements the existing support in elastic database query for horizontal partitioning (sharding) which is illustrated in the following figure. In contrast to SQL Server on-premises, elastic database query in Azure SQL Database now unifies both vertical an...
The maximum database size is 150GB, though this can be increased through sharding (the horizontal partitioning of data). This approach is also subject to more latency issues, due to the fact that it runs on a shared infrastructure in the Microsoft datacenter. ...
Learn about Database sharding, a form of partitioning that splits large databases into smaller components, which are faster and easier to manage.
