You have an Azure subscription that contains an Azure SQL database named SQLDB1 and an Azure Synapse Analytics dedicated SQL pool named Pool1. You need to replicate data from SQLDB1 to Pool1. The…

Azure Synapse Link for Azure SQL Database uses change feed technology to automatically replicate data changes from SQLDB1 to a Synapse dedicated SQL pool in near-real-time. It isolates analytical workloads from operational workloads, minimizing performance impact on SQLDB1, and requires minimal administrative configuration compared to traditional replication.

Azure Private Link is a networking feature that provides private connectivity to Azure services over a private endpoint; it does not replicate or synchronize data between databases.

SQL Data Sync is designed for bidirectional synchronization between Azure SQL databases but is not optimized for near-real-time analytics and introduces additional complexity and latency.

Transactional replication requires configuring a publisher, distributor, and subscriber with ongoing maintenance, resulting in higher administrative effort compared to Synapse Link.
