SQL Azure DB and include live query statistics

אני אוהב לאחד חידושים.
כאשר יצא SQLServer 2014
יצא גם DMV חדש
dm_exec_query_profiles
זה נתן לנו יכולת לעקוב אחרי התקדמות פעילויות כמו יצירת אינדקס או
Rebuild.
להלן לינק נחמד מאד שמסביר את זה
 
 
יש מספר סקריפטים שמראים כיצד להשתמש ולראות את התקדמות הבניה של האינדקס למשל:
 
 
SELECT
node_id,
physical_operator_name,
SUM(row_count) row_count,
SUM(estimate_row_count) AS estimate_row_count,
CAST(SUM(row_count)*100 AS float)/SUM(estimate_row_count) as estimate_percent_complete
FROM sys.dm_exec_query_profiles
WHERE session_id=@SPID 
GROUP BY node_id,physical_operator_name
ORDER BY node_id desc;
 
ב SQL Azure אני משתמש בו לעיתים תכופות - אולם פה אני מנצל את היכולת של ה PAAS, אני מעלה ל
Tielr גבוה מאד מריץ את מה שצריך להריץ - יודע בדיוק מתי זה ייגמר באמצעות שאילתא זו
ואז מוריד את ה Tier חזרה.
 
כמו שאמרתי אני משלב 2 חידושים - ה DMV והיכולת להעלות Tier ולהריץ דברים מאד מהר.
 
יש לציין שכרגע הסקריפט ירוץ או כאשר מדליקים ברמת הסשין דגל כלשהוא או שאני לוחץ על
"include live query statistics"
 
 

 
 
 
זהו לבנתיים
תנצלו את החידוש הזה
יום נעים

Extended Events in SQL Azure

Hi Everybody   Today an English post about 'Extended Events in SQL Azure', some of you shorten the name to 'EE' and some to 'XEvent'. I Love EE so this is how I will call it in this post.   This feature was introduce in SQL Server 2008 and its should help collecting DATA about what is running in the Server.   More Details about this SQL Server feature can be found in this Link: https://msdn.microsoft.com/library/bb630282.aspx?f=255&MSPPError=-2147217396   There are a few differences between EE in SQL Azure and regular SQL Server: In SQL Server versions the EE are on the Server level and therefore you create sessions on Server. In SQL Azure the server is a virtual entity - so the EE is in DB level and you create the session on DataBase. In SQL Server versions the EE can write to files on the server. SQL Azure does not have drives for files (SQL Azure is PAAS.....:-)). There is an option to write to blob storage, for this we need t...

How to restore deleted Azure Synapse dedicated SQL pool

  Existing dedicated pool can be easily restored from Azure portal or PowerShell command, but for now deleted pool could be restored from PowerShell only! Example: # Connect to Azure with system-assigned managed identity $AzureContext = (Connect-AzAccount -Identity).context # set and store context $AzureContext = Set-AzContext -SubscriptionName $AzureContext.Subscription -DefaultProfile $AzureContext # $AzureContext = Set-AzContext -SubscriptionName $SubscriptionName -DefaultProfile $AzureContext $SubscriptionName="Databases" $ResourceGroupName="stg-rg-we" $ServerName="stg-synapse-we"   $DatabaseName="sql_we_2023_11_07_13_42" $NewDatabaseName="sql_dp_we_deleted" ######################################## $token = (Get-AzAccessToken -ResourceUrl https://database.windows.net).Token $SubscriptionId = "ce088f9e-1111111a3914b" $DedicatedPoolEndPoint = "stg-synapse-we.sql.azuresynapse.net" $DedicatedPoolName = $DatabaseNam...

The journey to the Lakehouse

A long time has passed since the last post, we have gone through a long and tedious journey to adapt what Azure offers us, to our needs. Our needs were simple, the Current Datawarehouse (SQL Server on VM inazure) served the BI. ML teams worked on GCP, we want to let both teams to work on Azure in a platform that will have the ability to scale and will not fail every 2 days. We checked: Snowflake on azure Synapse analytics GCP We decided to go for the full Azure product for the reasons: Migration time support costs Synapse as a platform contains many components, and the challenge was to find what fits  us as an organization and as a group. The knowledge of the people and their abilities influenced the plans. Here's what we planned and what we did: We start to put everything in the Data Lake in parquet or delta format, build on top of Azure ADLS gen 2. We had to move some data to T-SQL compatible platform, so this involves setting up a dedicated Synapse pool , which is a fully man...
