You can now use Azure Synapse Link with Azure Cosmos DB serverless accounts. – Australian Energy Market Operator Azure Synapse Link compatibility with Azure Cosmos DB serverless With the significant amounts of data that our system brings in, the capability to do custom partitioning in Azure Cosmos DB’s HTAP functionality was essential for us to provide performant insights to our internal stakeholders.” “AEMO leverages Azure and Azure Cosmos DB to ingest terabytes of critical metering data. What customers say about Azure Synapse Link for Azure Cosmos DB In summary, custom partitioning can help improve analytical query performance when partition column(s) are used as query filters. To learn more, refer to our documentation. While querying, specify the same ”partition.keys” and ”basePath” configs, as defined in the partitioning job, to make use of the partitioned store in the query path.īelow filter will avoid scanning partitions other than “readDate = ‘’” partition:Īzure Synapse Link custom partitioning query

Please see configure custom partitioning to understand the different configurations, which can be used with custom partitioning.Īzure Synapse Link custom partitioning job definition code snippet Analytical query execution on partitioned store Each time you trigger the partitioning job, the incremental analytical store data will be partitioned and written to the partitioned store, which is indicated by the “basePath” config. In the below sample, the ”readDate” is chosen as the partition key.

You can also choose one or more fields from the dataset as the analytical store partition key. You can schedule it to run as a background job, once or twice a day, or it can be executed more often if needed. Partitioning can be triggered from an Azure Synapse Spark notebook using Azure Synapse Link. Instead of keeping track of multiple versions of records in the analytical store and loading them during each query execution, the partitioned store only contains the latest version of the data.ĭiagram of Azure Synapse Link custom partitioning architecture Triggering a custom partitioning job

The pruned data from the partitioned store is then automatically merged with the most recent non-partitioned data from the analytical store, returning near real-time results for your queries.īy compacting and optimizing the analytical data written to the partitioned store, custom partitioning al so helps to improve the query performance when there is a high volume of update or delete operations on the underlying Azure Cosmos DB container. Analytical queries with filters on the partition columns can benefit from partition pruning and avoid scanning any partition that does not satisfy the filters. Partitioned data from the Azure Cosmos DB analytical store is written to the partitioned store, which points to the primary storage account linked to your Azure Synapse workspace. If your analytical queries have frequently used filters, you now have the option to partition based on these fields. By default, data in Azure Cosmos DB analytical store is not partitioned. You can now use custom partitioning to improve analytical query performance. Custom partitioning for analytical workloads

In addition to custom partitioning, this blog post also covers two Azure Synapse Link capabilities that have been enabled in the last few months: serverless compatibility and full fidelity schema. This capability improves query performance by enabling you to partition Azure Cosmos DB analytical store data using keys that are frequently used as query filters. Today, we are excited to announce that custom partitioning is in preview for Azure Synapse Link for Azure Cosmos DB. This blog post was co-authored by Revin Chalil, Rodrigo Souza and Anitha Adusumilli from the Azure Cosmos DB Team. toString ( ) Ĭonst encryptSource = 'ax5' + name + 'b52w' + salt + 'vb3'
