将云中的数据库同步到本地以进行读取规模——如何触发同步？

Question

We are planning to have a subset of our main DB (which is in the cloud) in our on-prem server. It would be for a few tables...and would scale out based on performance needs. We are trying to figure out how to trigger the sync from Azure to on-prem? which azure components and db features to use in this case?

Thanks

You could think about using Azure SQL database Data Sync feature:

• SQL Data Sync is a service built on Azure SQL Database that lets you synchronize the data you select bi-directionally across multiple databases, both on-premises and in the cloud.
• Data Sync uses a hub and spoke topology to synchronize data. You define one of the databases in the sync group as the hub database. The rest of the databases are member databases. Sync occurs only between the hub and individual members.

You could create the Data Sync between Azure SQL database and on-premise SQL Server. Set the Azure SQL database as hub database, on-premise SQL Server ad member database, and Sync Direction: Hub to member. This will help sync data from Azure to on-prem.

The Sync group will sync the data every 5 mins automatically. You also could sync data manually.

HTH.
