超大規模化彈性集區2024 年 9 月使用超大規模資料庫彈性集區管理及擴展 Azure SQL 資料庫中的多個超大規模資料庫。 Hyperscale elastic pools also support Premium-series hardware and zone redundancy. 如需詳細資訊,請參閱超大規模資料庫彈性集區現已全面推出。
有关SQL 数据库内置策略定义的完整列表,请查看策略参考。 重要 通过T-SQL 创建数据库时,不会强制实施 Azure 策略。 若要在使用 T-SQL 创建数据库时指定数据驻留,请使用 LOCAL 或 ZONE 作为 CREATE DATABASE 语句中 BACKUP_STORAGE_REDUNDANCY 参数的输入。
YDB's built-in automatic recovery support allows it to seamlessly survive hardware failures. After unpredictable disk, node, rack, or even datacenter failure, YDB remains fully available for reads and writes and automatically restores required data redundancy. ...
Learn reasons behind SQL Database Cyclic Redundancy Check (CRC) error, scenarios in which you can encounter SQL CRC error, and how to fix it.
Database mirroring in SQL Server allows you to keep a copy, or mirror, of a SQL Server 2005 database on a standby server. Mirroring ensures that two separate copies of the data exist at all times, providing high availability and complete data redundancy. The .NET Data Provider for SQL ...
When binary checksums are used, 32-bit redundancy check (CRC) occurs on a column-by-column basis rather than a CRC on the physical row on the data page. This allows the columns with the table to be in any order physically on the data page, but still compute to the same CRC for the...
Having extra copies of the database is the tradeoff for ensuring redundancy. An example of an AG that spans multiple data centers is shown below. One primary replica is responsible for keeping all secondary replicas synchronized. Outside of an AG with a cluster type of none, an AG requires ...
In this article, we have discussed the problem of SQL data error cyclic redundancy check. We have given the various causes of this CRC error. To resolve this problem the user can try the manual method. In case if your SQL server database is corrupted then the user can take the help of...
