SynapseSqlPoolExecRequests:

This log contains detailed information about queries executed in a dedicated SQL pool in Azure Synapse Analytics.

It provides metrics such as query duration, CPU time, I/O, and the status of the queries, making it the best choice for monitoring query performance.

Other options:

A. SynapseSqlPoolSqlRequests:

Logs high-level requests, such as login attempts or connection establishment. It doesn’t give detailed query execution information.

C. SynapseSqlPoolWaits:

Contains information about waits in the SQL pool, useful for troubleshooting resource contention but not suitable for directly monitoring query performance.

D. SynapseSqlPoolRequestSteps:

Provides information about the individual steps within a query plan, which is more granular and not typically used for general query performance monitoring.

Guarantee Stream Analytics job reliability during service updates

Part of being a fully managed service is the capability to introduce new service functionality and improvements at a rapid pace. As a result, Stream Analytics can have a service update deploy on a weekly (or more frequent) basis. No matter how much testing is done there is still a risk that an existing, running job may break due to the introduction of a bug. If you are running mission critical jobs, these risks need to be avoided. You can reduce this risk by following Azure’s paired region model.

Scenario: The application development team will create an Azure event hub to receive real-time sales data, including store number, date, time, product ID, customer loyalty number, price, and discount amount, from the point of sale (POS) system and output the data to data storage in Azure

Virtual network rules are one firewall security feature that controls whether the database server for your single databases and elastic pool in Azure SQL Database or for your databases in SQL Data Warehouse accepts communications that are sent from particular subnets in virtual networks.

Server-level, not database-level: Each virtual network rule applies to your whole Azure SQL Database server, not just to one particular database on the server. In other words, virtual network rule applies at the serverlevel, not at the database-level.
