azure sql hyperscale vs synapse

A Hyperscale database is a database in SQL Database that is backed by the Hyperscale scale-out storage technology. This avoids poor read performance on secondary replicas and long recovery after failover to an HA secondary replica. Scales storage up to 100 TB with Azure SQL Database Hyperscale. A Hyperscale database is created with a starting size of 10 GB and grows as needed in 10GB chunks. All Rights Reserved. Whereas Azure SQL Database offers basic data replication options such as read replicas, automatic failover, and point-in-time restore to help ensure data availability and recovery. Hi Bedant, If my answer is helpful for you, you can accept it as answer( click on the check mark beside the answer to toggle it from greyed out to filled in.). Note: In product documentation and in blogs, you will also see Dedicated SQL pool (formerly SQL DW) sometimes referred to as standalone dedicated SQL pool as makes sense when looking at the above diagram. Restore time may be longer for larger databases, and if the database had experienced significant write activity before and up to the restore point in time. If the data being accessed is cached in RBPEX on the compute replica, you will see similar IO performance as in Business Critical or Premium service tiers. In effect, database backup in Hyperscale is continuous. Custom Logging in Azure Data Factory and Azure Synapse Analytics Christianlauer in Geek Culture Azure Synapse Analytics vs. Databricks Sven Balnojan in Geek Culture 10 Surprising. This includes customers who are moving to the cloud to modernize their applications and customers who are already using other service tiers in Azure SQL Database. HA secondary replicas are used as high availability failover targets, so they need to have the same configuration as the primary to provide expected performance after failover. For an introduction to Hyperscale, we recommend you refer to the, Fast database backups regardless of database size (backups are based on storage snapshots), Fast database restores regardless of database size (restores are from storage snapshots), Higher log throughput regardless of database size and the number of vCores. That way there is a hot-standby replica available that serves as a failover target. Synapse Vs Azure SQL Hyperscale Again, this is not available in Azure SQL Database, where users would need to manually monitor their databases for potential security threats. It functions as a single pane of glass for building, testing, and viewing the results of queries. Whats the recommended Azure SQL DW DB to use with Synapse? Backup billing in the serverless compute tier is the same as in the provisioned compute tier. The time to replay changes will be shorter if the move is done during a period of low write activity. For read-intensive workloads, the Hyperscale service tier provides rapid scale-out by provisioning additional replicas as needed for offloading read workloads. Some Azure SQL Database features are not supported in Hyperscale yet. With the ability to rapidly spin up/down additional read-only compute nodes, the Hyperscale architecture allows significant read scale capabilities and can also free up the primary compute node for serving more write requests. Add HA replicas for that purpose. For mission-critical apps that require high availability with minimal failover impact, you should provision at least one HA secondary replica. We're actively working to remove as many of these limitations as possible. Reverse migration to the General Purpose service tier allows customers who have recently migrated an existing database in Azure SQL Database to the Hyperscale service tier to move back, should Hyperscale not meet their needs. The Hyperscale service tier in Azure SQL Database provides the following additional capabilities: Support for up to 100 TB of database size. A non-Hyperscale database can't be restored as a Hyperscale database, and a Hyperscale database can't be restored as a non-Hyperscale database. Full recovery model is required to provide high availability and point-in-time recovery. With Hyperscale, you can use three kinds of secondary replicas to cater for read scale-out, high availability, and geo-replication requirements. Following up to see if the above suggestion was helpful. Details on how to measure backup storage size are captured in Automated Backups. Synapse provides a highly scalable and flexible platform for storing and processing large volumes of data. Support geo-redundant backups. Also, the compute nodes can be scaled up/down rapidly due to the shared-storage architecture of the Hyperscale architecture. You cannot use any of the options you mentioned for a data warehouse in Synapse. Reference: Snowflake vs Azure SQL Database Comparison My data needs are not so vast to utilize the MPP. The Hyperscale architecture provides high performance and throughput while supporting large database sizes.
