“Dedicated SQL Pools Get a Boost with Multi-Column Distribution – Now Generally Available!”
Multi-Column Distribution for Dedicated SQL Pools is Now GA!
Introduction to Multi-Column Distribution
Multi-column distribution is an important feature for optimizing the performance of large-scale data warehouses. It allows for data to be distributed across multiple columns, which can improve query performance by allowing for parallelism and reducing the amount of data that needs to be moved. Azure Synapse Analytics now supports multi-column distribution for dedicated SQL pools through the new Multi-Column Distribution feature, making it easier for customers to take advantage of this performance optimization.
Benefits of Multi-Column Distribution
Multi-column distribution has many benefits, including:
* Improved query performance: By distributing data across multiple columns, the query can be parallelized, reducing the amount of data that needs to be moved and improving query performance.
* Improved data locality: By distributing data across multiple columns, the data can be placed closer together, reducing the amount of time it takes to move the data between nodes.
* Improved scalability: By allowing for larger data sets to be distributed across multiple columns, Synapse Analytics can scale to larger data sets without sacrificing performance.
Implementing Multi-Column Distribution
The Multi-Column Distribution feature in Azure Synapse Analytics is available for dedicated SQL pools. It allows customers to specify which columns to distribute data across and how to distribute it. This can be done either manually or using the new Multi-Column Distribution Wizard.
Using the Multi-Column Distribution Wizard
The Multi-Column Distribution Wizard makes it easy to implement multi-column distribution in Azure Synapse Analytics. It allows customers to select the columns they want to distribute across and the distribution method they want to use. The wizard will then generate the appropriate T-SQL code to implement the multi-column distribution.
Conclusion
The new Multi-Column Distribution feature in Azure Synapse Analytics makes it easier for customers to take advantage of the performance benefits of multi-column distribution. With the Multi-Column Distribution Wizard, customers can quickly and easily implement multi-column distribution for dedicated SQL pools, allowing them to scale their data warehouses to larger data sets without sacrificing performance.
