Tumbling window self-dependency properties

In scenarios where the trigger shouldn't proceed to the next window until the preceding window is successfully completed, build a self-dependency. A self-dependency trigger that's dependent on the success of earlier runs of itself within the preceding hour will have the properties indicated in the following code.

Example code:

"name": "DemoSelfDependency",

"properties": {

"runtimeState": "Started",

"pipeline": {

"pipelineReference": {

"referenceName": "Demo",

"type": "PipelineReference"

}

},

"type": "TumblingWindowTrigger",

"typeProperties": {

"frequency": "Hour",

"interval": 1,

"startTime": "2018-10-04T00:00:00Z",

"delay": "00:01:00",

"maxConcurrency": 50,

"retryPolicy": {

"intervalInSeconds": 30

},

"dependsOn": [

{

"type": "SelfDependencyTumblingWindowTriggerReference",

"size": "01:00:00",

"offset": "-01:00:00"

}

]

}

}

}

Box 1: A Get Metadata activity

Dynamically size data flow compute at runtime

The Core Count and Compute Type properties can be set dynamically to adjust to the size of your incoming source data at runtime. Use pipeline activities like Lookup or Get Metadata in order to find the size of the source dataset data. Then, use Add Dynamic Content in the Data Flow activity properties.

Box 2: Dynamic content

Transparent Data Encryption (TDE) helps protect against the threat of malicious activity by encrypting and decrypting your data at rest. When you encrypt your database, associated backups and transaction log files are encrypted without requiring any changes to your applications. TDE encrypts the storage of an entire database

by using a symmetric key called the database encryption key.

Scenario: Identify a process to ensure that changes to the ingestion and transformation activities can be version-controlled and developed independently by multiple data engineers.

Step 1: Create a repository and a main branch

You need a Git repository in Azure Pipelines, TFS, or GitHub with your app.

Step 2: Create a feature branch

Step 3: Create a pull request

Step 4: Merge changes

Merge feature branches into the main branch using pull requests.

Step 5: Publish changes
