When you register a data asset, choose Include Data Profile in the data source registration tool. It's easy to include a profile of your data assets. And for that you need a Storage Account and somehow allow the database to write to it. The Data Profiling feature of Azure Data Catalog examines the data from supported data sources in your catalog and collects statistics and information about that data. You need to use a path to a storage container.

This is because you do not have a concept of local storage. While the file-target is the easiest one to use on Premise, in Azure SQL Database there are some obstacles.

I have an example here: How to import Extended Events session event_file target and parse deadlock-graph The Ring-Buffer target can be parsed for further analysis via XQuery. I can only guess that this was based on real-world usage, and I find very few people who actually know about that special target’s advantages. That one has capabilities that no other target has! And it’s not more complicated to support. What I do not understand is, why Microsoft did not provide the pair_matching target. And also, technically a file-target can easily give you a count. Why the event_counter-target, why not histogram or pair_matching? From the extensive benchmarks I have done ( Performance overhead of tracing with Extended Event targets vs SQL Trace under CPU Load), I know that the counter-target really does not have any less overhead than the file-target. Now I am not sure this choice makes a lot of sense. Here we are really limited: All that we can choose from is: Then you will need to decide for a target. Get current sqlserver instance winfab replica id. Get current sqlserver instance winfab partition id. Get the last error number from the current worker. Get the high key of the current partition. Get the low key of the current partition. Get the table group name of the current partition. Get the app name of the current partition. Get whether current session is an azure connection. The list of special azure-predicates as of today is: Predicate If you hoped to use SQLTrace/Profiler for Tracing, from looking at this list alone you can tell there is no way for this old, outdated tool from the last decade in Azure SQL Database. or when did the garbage collector of my memory optimized table occur and how many rows did it remove?”.columnstore_tuple_mover_end_delete_buffer_flush.columnstore_tuple_mover_delete_buffers_swapped.columnstore_tuple_mover_delete_buffer_truncated.columnstore_tuple_mover_delete_buffer_truncate_timed_out.columnstore_tuple_mover_delete_buffer_truncate_requirements_not_met.columnstore_tuple_mover_delete_buffer_flush_requirements_not_met.columnstore_tuple_mover_compression_stats.columnstore_tuple_mover_begin_delete_buffer_flush.“how exactly did the tuple mover process for my columnstore Index run?”.“What prevented adaptive query plan usage?”.When you open it, it will open as the graphical representation of the query plan. sqlplan extension, then open it again later if required. Clicking it opens the XML document in a new tab. You can click on the XML Showplan to open the XML document. If you click the tab after getting the estimated plan, then you’ll only see the XML query plan. If you click this tab after getting the actual query plan, you’ll see the result of the query as well as the XML query plan (as shown in the above screenshot). You can click on the Results tab to get an XML representation of the query plan. I can now see that the Actual Rows and Actual Executions contain actual data (as opposed to the zeros that were in the estimated query plan). In my case the actual execution plan looks the same as the estimated one:īut when I click on the Top Operations tab, it’s a different story: It will now run the query with the actual query execution plan. To do this, open a tab and write your query (or highlight the query if it’s sitting amongst other queries on the same tab).Īnd then type Run Current Query with Actual Plan and click on the same text that should now appear. To get the actual query execution plan, you need to run the actual query with the query plan.

If your query tab contains multiple statements but you only want the query plan for one, you can highlight that statement (just like when you highlight one when you only want to execute that statement). We can see that the Actual Rows and Actual Executions columns contain zeros, while the Est Cost, Est Subtree Cost, and Est Rows are filled with nonzero data. We can tell that this is only an estimated query plan when we click on the Top Operations tab. To view the estimated query plan in Azure Data Studio, simply click on the Explain button at the top of your query tab.Ĭlicking Explain will automatically display the query execution plan in the bottom pane. It does this without actually running the query. The estimated query execution plan shows you an estimation of what the query plan would look like if you were to run it. If you use Azure Data Studio for your database admin tasks, you might be wondering how you can view the execution plan for your queries?
