The second method is to use sys.tables system table to check the existence of the table in Azure synapse analytics server. The following query will check the Customer table existence in the default dbo database, and if it exists, it will be dropped. IF EXISTS (SELECT [name] FROM sys.tables WHERE [name] like 'Customer%') BEGIN DROP TABLE.
Dynatrace ingests metrics from Azure Metrics API for Azure Analytics (Synapse Workspace, Apache Spark pool, SQL pool). You can view metrics for each service instance, split metrics into multiple dimensions, and create custom charts that you can pin to your dashboards.
In Azure Synapse, system configurations of spark pool look like below, where the number of executors, vcores, memory is defined by default. There could be the requirement of few users who want to manipulate the number of executors or memory assigned to a spark session during execution time. .
Enable Azure Synapse Link. Once the Cosmos DB Account is created, we will need to enable the Azure Synapse Link which by default is set to 'Off'. This can be achieved by clicking on the Azure Synapse Link feature and Enabling Azure Synapse Link. Once Azure Synapse Link is enabled, the Status will be changed to On.
Today, we are making this possible by releasing an indexing subsystem for Apache Spark called Hyperspace - the same technology that powers indexing within Azure Synapse Analytics. Build indexes on your data (e.g., CSV, JSON, Parquet). Maintain the indexes through a multi-user concurrency model. Leverage these indexes automatically, within.
Analyze sample data with spark pool. As a first step we are going to load the sample data file from storage into spark dataframe using PySpark code. The scripts will be executed in the cells present in the notebook and it offers support for many languages like PySpark, .net (c#), scala etc., for you to run your query. This forms the basis of three important features of Databricks that need an alternative in the synapse: 1. Replacing Azure Key vault backed Databricks secret scope. Writing secure code is a key aspect any developer needs to know. At no place, the sensitive information like passwords can be exposed. Azure Key vault is a Microsoft Azure service.
