For read workloads, this can be achieved using named replicas. Other than the restrictions stated, you do not need to worry about running out of log space on a system that has high log throughput. For read workloads, you can create a named replica with a higher compute size (more cores and memory) than the primary. There has been confusion for a while when it comes to Microsoft Docs and the two distinct sets of documentation for dedicated SQL pools. Relational DBMS. Following up to see if the above suggestion was helpful. For more information about Hyperscale pricing, see Azure SQL Database Pricing. This includes: No, your application programming model stays the same as for any other MSSQL database. To add HA replicas for a named replica, you can use the parameter ha-replicas with AZ CLI, or the parameter HighAvailabilityReplicaCount with PowerShell, or the highAvailabilityReplicaCount property with REST API. The time to replay changes will be shorter if the move is done during a period of low write activity. A new connection with read-only intent is redirected to an arbitrary HA secondary replica. describes that Azure SQL (#2 above) uses symmetric multiprocessing (SMP) while "Azure Synapse Analytics" (#1) above uses massively parallel processing (MPP). Downtime for migration to Hyperscale is the same as the downtime when you migrate your databases to other Azure SQL Database service tiers. Changing default MAXDOP in Azure SQL Database and Azure SQL Managed Both Azure Synapse Analytics and Azure SQL Database offer automatic backups, but there is a difference in the backup retention periods they provide. Additionally, consider configuring a maintenance window that matches your workload schedule to avoid transient errors due to planned maintenance. In other words, its great for handling complex and ad-hoc analysis of data in real time. Migration of a dedicated SQL pool (formerly SQL DW) in relative terms is easy.

Because the storage is shared and there is no direct physical replication happening between primary and secondary compute replicas, the throughput on primary replica will not be directly affected by adding secondary replicas. While both services provide data replication features, Azure Synapse Analytics provides more extensive options for data replication. Do let us know if you any further queries. On the Read Scale-out secondary replicas, the default isolation level is Snapshot. Named replicas, under normal circumstances, are unlikely to impact the primary's performance, but it can happen if there are intensive workloads running. Both platforms offer similar features, such as parallel processing and distributed data analysis across multiple nodes in the cloud. Get sample code to migrate existing Azure SQL Databases to Hyperscale in the Azure portal, Azure CLI, PowerShell, and Transact-SQL in Migrate an existing database to Hyperscale. There is no Azure SQL DW Hyperscale, sorry, it never existed. If a named replica, for any reason, is not able to consume the transaction log fast enough, it will start asking the primary replica to slow down (throttle) its log generation, so that it can catch up. Scaling up or down in the provisioned compute tier typically takes up to 2 minutes regardless of data size. Side Note: Historians will remember the appliance was named parallel data warehouse (PDW) and then Analytics Platform System (APS) which still powers many on-premises data warehousing solutions today. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Yes.

On the other hand, Azure SQL Database is a better choice for smaller database sizes, as it can efficiently scale up or down based on workload demands. Note the endpoint DNS change. Azure Data Factory, Azure Databricks, SSIS, etc. Elastic pools do not support the Hyperscale service tier. A quick way to visualize this as a blend of all the additional Synapse Analytics workspace capabilities and the original SQL DW is below. Users may adjust the total number of high-availability secondary replicas from 0 to 4, depending on availability and scalability requirements, and create up to 30 named replicas to support a variety of read scale-out workloads. Hyperscale databases have shared storage, meaning that all compute replicas see the same tables, indexes, and other database objects. One of the biggest areas of confusion in documentation between "dedicated SQL pool (formerly SQL DW)" and "Synapse Analytics" dedicated SQL pools is PowerShell. What tool can be used to MIGRATE SQL Server DB/DW to Azure Synapse (formerly Azure SQL DW)? You can only create multiple replicas to scale out read-only workloads.
