Azure Data Factory Interview Questions Part -01

The difference between Azure Table Storage and Azure SQL Service are as follows:

Table Storage Service

1. It has a NoSQL type of storage on Azure.

1. It has a relational storage structure on Azure.

2. The data is stored in key-value format and is called Entity.

2. The data is stored in rows and columns combination in an SQL table.

3. The data schema is not enforced for storage.

3. The data schema is enforced for storing data. Error occurs if schema is violated.

4. The partition and row key combination are unnique for each identity.

4. With the help of primary or unique key, uniqueness can be defined.

5. There is no relationship between tables.

5. Relationship between tables can be created with the help of foreign keys.

6. The table storage service can be used gor storing log information or diagnostics data.

6. The Azure SQL table can be used for transaction-based applications.

What Are The Instance Types Presented By Azure

There are different types of instances on the basis of different needs they are useful in:

  • General purpose: CPU to memory ratio is balanced. It provides low to medium traffic servers, small to medium databases. It is the best for testing and development. Largest instance size: Standard_D64_v3 256 GB Memory and 1600 GB SSD Temp Storage
  • Compute Optimized: High CPU to memory ratio. It is the best for medium traffic web servers, application servers, and network appliances. Largest instance size: Standard_F72s_V2 144 GB Memory and 576 GB SSD Temp Storage
  • Memory-Optimized: High memory to CPU ratio. It works the best for relational database servers, in-memory analytics and medium to large sized caches. Largest instance size: Standard_M128m 3892 GB Memory and 14,336 SSD Temp Storage
  • Storage-Optimized: It provides high disk IO and throughput. It is the best suited for Big Data, NoSQL and SQL databases. Largest size instance: Standard_L32s 256 GB Memory and 5630 GB SSD Temp Storage
  • GPU: These are the virtual machines that have the heavy graphic rendering and video editing. It helps with model training and developing inferences with deep learning. Largest instance size: Standard_ND24rs 448 GB Memory and 2948 GB SSD Temp Storage 4 GPUs and 96 GB Memory
  • High-Performance Compute: It provides Azures fastest and most powerful CPU virtual machine with optional high throughput interfaces. Largest instance size: Standard_L32s 224 GB Memory and 2000 GB Temp storage

Mention About Three Types Of Triggers That Azure Data Factory Supports

  • The Schedule trigger is useful for the execution of the ADF pipeline on a wall-clock timetable.
  • The Tumbling window trigger is useful for the execution of the ADF pipeline over a cyclic interval. It holds on to the pipeline state.
  • The Event-based trigger responds to an event that is related to blob. Examples of such events include adding or deleting a blob from your Azure storage account.

    Mentions The Steps For Creating Etl Process In Azure Data Factory

    Saiba tudo sobre o Azure Data Factory

    When attempting to retrieve some data from Azure SQL server database, if anything needs to be processed, it would be processed and saved in the Data Lake Store. Here are the steps for creating ETL:

    • Firstly, create a Linked Service for source data store i.e. SQL Server Database
    • Suppose that we are using a cars dataset
    • Now create a Linked Service for a destination data store that is Azure Data Lake Store
    • After that, create a dataset for Data Saving
    • Setup the pipeline and add copy activity
    • Finally, schedule the pipeline by inserting a trigger

    Is It Possible To Have Nested Looping In Azure Data Factory

    There is no direct support for nested looping in the data factory for any looping activity . However, we can use one for each/until loop activity which will contain an execute pipeline activity that can have a loop activity. This way, when we call the loop activity it will indirectly call another loop activity, and well be able to achieve nested looping.

    What Are The Key Differences Between Azure Data Lake And Azure Data Warehouse

    Azure Data Lake and Azure Data Warehouse are widely used to store big data, but they are not synonymous, and we can’t use them interchangeably. Azure Data Lake is a huge pool of raw data. On the other hand, Azure Data Warehouse is a repository for structured, processed, and filtered data already processed for a specific purpose.

    Following is a list of key differences between Azure Data Lake and Azure Data Warehouse:

    Azure Data Lake Azure Data Warehouse Azure Data Lake has a raw data structure. Raw data means data that has not yet been processed for a specific purpose. Azure Data Warehouse has a processed data structure. The processed data means the data that a larger audience can easily understand. It is primarily used to store raw and unprocessed data. It is primarily used to store only processed data, saving storage space by not maintaining data that may never be used. Azure Data Lake is complementary to Azure Data Warehouse. In other words, we can say that if you have your data at a data lake, it can be stored in the data warehouse as well, but you must have to follow certain rules. Azure Data Warehouse is a traditional way of storing data. It is one of the most widely used storage for big data. The purpose of data storing in the Azure Data Lake is not yet determined. The purpose of data storing in the Azure Data Warehouse is worthy because it is currently in use. It uses one language to process data of any format. It uses SQL because data is already processed.

    How Does Azure Data Factory Work

    Azure Data Factory processes the data from the pipeline. It basically works in the three stages:

    Connect and Collect:

    Connects to various SaaS services, or FTP or File sharing servers. Once the Azure Data Factory secures the connection, it starts collecting the Data from therein. There are on-premise sources and cloud storage. Azure Data Factory collects the information from all the sources available to make it available to one centralized source.

    Transform and Enrich:

    Once the collection of Data is done, all the data is transformed. The transformation could be done using various methods like HDInsight Hadoop, Spark, Data Lake Analytics, and Machine Learning.

    Publish:

    The transformed data is then available on the local storage or local cloud space in the form of SQL. The data is in centralized storage, to be accessed and processed by BI and analytical teams.

    Data migration activities with Data Factory

    Data Migration takes place in one of the two forms: From one data storage to another. From on-premise to cloud storage or vise versa.

    Azure Data Migration Copy Activities:

    The Copy Activities in Azure Data Migration are responsible for copying the source data to the sink data store.

    The data stores – both source and sink, that Azure supports are – Azure Blob storage, Azure Cosmos DB , Azure Data Lake Store, Oracle, Cassandra, and a few others.

    What Is The Meaning Of Application Partitions

    Explanation: The application partitions are a part of the Active Directory system and having said so, they are directory partitions which are replicated to domain controllers. Usually, domain controllers that are included in the process of directory partitions hold a replica of that directory partition. The attributes and values of application partitions is that you can replicated them to any specific domain controller in a forest, meaning that it could lessen replication traffic. While the domain directory partitions transfer all their data to all of the domains, the application partitions can focus on only one in the domain area. This makes application partitions redundant and more available.

    What Is The Key Difference Between The Dataset And Linked Service In Azure Data Factory

    Dataset specifies a reference to the data store described by the linked service. When we put data to the dataset from a SQL Server instance, the dataset indicates the table’s name that contains the target data or the query that returns data from different tables.

    Linked service specifies a description of the connection string used to connect to the data stores. For example, when we put data in a linked service from a SQL Server instance, the linked service contains the name for the SQL Server instance and the credentials used to connect to that instance.
