SQL Server Drawbacks

Apart from the multiple advantages of Databricks, there are some inherent drawbacks of SQL Server which may motivate users to move to Databricks. SQL Server CDC To Kafka (Unbelievably Easy New Connector)

The SQL user interface is not easy to work with

SQL has a user interface that makes things appear more complicated than they actually are. The interface can prove intimidating to users.

Performance tuning in SQL Server can be complicated

Users without specialized knowledge may find query optimization and performance tuning challenging. for very large data sets. BryteFlow for SQL Server Replication

SQL Server can have high licensing costs

Though free versions of the SQL Server software are available for educational or development purposes, there is a licensing fee for commercial use. SQL Server licensing is evolving constantly and can be difficult to get your head around.

SQL Server needs high security

SQL Server databases are under threat very often since the database does have vulnerabilities, regardless of version. Also, the databases have a lot of sensitive data that make them prime targets for security breaches.

SQL Server users get limited control over data

Users of SQL are not given total control over databases due to some business rules that are not apparent.

SQL Server source control support may be lacking

There is no native source control support in SQL Server. You need to use third-party tools to keep track of changes made to database objects.

How to connect and load data from SQL Server to Databricks

Here we look at 3 ways you can connect Databricks to SQL Server and load data into a Delta Lake-backed Databricks Lakehouse. Data that is migrated to Databricks lands into the Delta Lake layer. Databricks vs Snowflake: 18 differences you should know

What is Delta Lake?

The Databricks Lakehouse Platform’s foundation for storing tables and data is Delta Lake, the optimized storage layer that sits on top of a data lake. Delta Lake is open-source software and adds a file-based transaction log to Parquet data files for ACID transactions and scalable metadata handling. Delta Lake is fully integrated with Structured Streaming and Apache Spark APIs. This makes it simple to use a single copy of the data for both batch and streaming operations and provides incremental processing of data at scale. Delta Lake supports batch data processing, unified streaming, ACID transactions, and scalable metadata. Databricks and Delta Lake – A Dynamic Duo

Data Type Mapping for moving data from SQL Server to Databricks

Databricks does not support all data types. As a result, it is necessary to manually adjust the MSSQL data types to their equivalent Databricks data types in order to connect and load data from SQL Server to Databricks.

Auto Loader

Auto Loader is a Databricks feature that without any additional setup, can process new data files incrementally as they arrive in Cloud storage. It enables rapid ingestion of data from Azure Data Lake Gen2, Amazon S3 and Google Cloud Storage. Auto Loader has the capability to load data files from Databricks File System (DBFS, dbfs:/), AWS S3 (s3://), Azure Data Lake Storage Gen2 (ADLS Gen2, abfss://), Google Cloud Storage (GCS, gs://), Azure Blob Storage (wasbs://), and ADLS Gen1 (adl://).

Auto Loader provides a Structured Streaming source called cloudFiles. Provided there is an input directory path on the cloud file storage, new files are automatically processed by the cloudFiles source as they land, with the option of also processing existing files in that directory. JSON, CSV, PARQUET, AVRO, ORC, TEXT, and BINARY FILE formats are all supported by Auto Loader. Databricks Auto Loader uses Structured Streaming and checkpoints to process files when they land in the specified directory. Auto Loader has the capability to process millions of files and supports both – near real-time ingestion and batch processing. In Delta Live Tables, Auto Loader supports both, Python and SQL.

Conversion of Parquet or Iceberg data to Delta Lake and Databricks Clone functionality

Parquet and Iceberg tables stored in external locations managed by Unity Catalog can be converted to Delta Lake tables once with the CONVERT TO DELTA SQL command, for querying on the Databricks Lakehouse. Existing Parquet files can be configured as external tables in Unity Catalog and converted to Delta Lake to benefit from all the features of the Databricks Lakehouse.

For incremental conversion of data, the Databricks clone functionality can be used. It combines Delta table cloning and conversion of tables to Delta Lake format. Databricks Clone can be used to ingest Parquet or Iceberg data in the following circumstances:

  • While performing migration from Parquet and Iceberg to Delta Lake but source tables are needed to be in use afterwards.
  • An ingest-only sync is required between target and source that gets the updates, deletes, and inserts.
  • An ACID-compliant source data snapshot needs to be created for machine learning, batch ETL or reporting.

Manually connect SQL Server to Databricks to load data

Here we will show you a manual method to connect and transfer data from MSSQL to Databricks by generating data in CSV files using SQL Server Management Studio and loading them in Databricks through the Add Data UI. However, there may be errors due to differences in data type compatibility between the two databases. BryteFlow for SQL Server Replication

What is MSSQL Server Management Studio?

SQL Server Management Studio (SSMS) is a single platform that can handle various aspects of SQL infrastructure. You can access, configure, administer, and manage all elements associated with SQL Servers. It has a diverse range of graphical tools and script editors that provide developers and database administrators a comprehensive utility to interact with SQL Server. Here we will use MSSQL Server Management Studio to export data in CSV file format for importing it into Databricks using the Databricks Add Data UI.

What is Add Data UI in Databricks?

The Databricks user interface (UI) provides a visual platform for accessing various functionalities, including workspace folders, their contents, data objects, and computational resources. The Add Data UI enables you to effortlessly import data into Databricks from diverse sources. Through the Add Data UI you can upload CSV, TSV, or JSON files to either create a new managed Delta Lake table or overwrite an existing one.

It is possible to upload data to the staging area without creating a connection to compute resources, but it is imperative to choose an active compute resource to preview and configure your table. You can preview upto 50 rows from your data when configuring options for the uploaded table. The data files for managed tables in Databricks are stored in the locations specified for the associated schema configuration. You must have the correct permissions to create a table within a schema. You can create managed Delta tables in the Unity Catalog or in the Hive Metastore.

Limitations of Databricks Add Data UI (Upload)

  • It supports only CSV, TSV, or JSON files.
  • Only 10 files can be uploaded at a time with Upload UI.
  • The total file size of the uploads must not be more than 100 megabytes.
  • The file must be a CSV, TSV, or JSON and have the extension “.csv”, “. tsv”, or “. json”.
  • Zip, Tar and other compressed files are not supported.

These are the main steps in manual Migration of CSV data from SQL Server to Databricks

1.1   Export MS SQL data into intermediate storage using SQL Server Management Studio.

1.2   Load data into Databricks through the Add Data UI.

1.3   Update the table details and convert the data types into Databricks Delta Lake format.

1.1 Export MS SQL data into intermediate storage – using SQL Server Management Studio.

We can use the SQL Server Management Studio to copy the data into an intermediate storage before loading into Databricks. Follow the steps mentioned below to export the data:

Step 1: Open MS SQL Server Management Studio. Then connect to the MS SQL Server. Go to the database that needs to be migrated. Right click on the database > Tasks > Export data.

Step 2: In the “Choose a Data Source” window.  Select “SQL Server Native Client” from the Data source drop-down list. Then choose “Windows Authentication”, and your Database from which the data will be exported. Once that’s done, click the “Next” button.

Step 3:  From the “Choose a Destination” window, you have three options to export data – CSV, Excel or Flat File. Here we choose “Destination as CSV”.

Destination as CSV CSV files are the simplest files for storing and transferring large amounts of data. Select “Flat File” from the Destination drop-down list. In the “File Name” text box, give the path and file name of the CSV file or select the file by browsing. Then give the file extension as “.CSV”. Select the format. Once done, click the “Next” button.

Step 4: In the “Specify Table Copy or Query” window, choose the “Copy data from one or more tables or views” option.

Step 5: The next window is the “Configure Flat File Destination” for CSV files. In this window, you have the option to select one or multiple tables or views for exporting data. After making your selections, you will need to specify the characters that will be used as delimiters for the destination file, both for rows and columns. The “Preview” button in this window allows you to preview the data that will be exported.

Step 6: In the “Save and Run Package” window, you have the option to decide what happens to the data in the SQL Server database. You can choose to export it to a CSV file right away by selecting the “Run immediately” option, or you can save the copied data as an SSIS package by selecting the “Save SSIS Package” checkbox. Once you’ve made your choice, you can either click the “Finish” button or proceed to the review step by clicking the “Next” button.

Step 7: The “Complete the Wizard” window, is the last step in which decisions that were made in the wizard can be verified. Once everything is confirmed, click the “Finish” button to complete the process. Following that, a final step will appear, displaying progress and status details regarding the export of SQL Server data.

1.2 Load data into the Databricks through Add Data UI

Step 1: Open Databricks.

Make sure the cluster is up and running. Then go to the “New” tab and click on “Data” tab.

Step 2: Once the Data tab is open, it opens the “Add Data” window. Select “Upload Data” option.

Step 3: Then, with the “Upload Data” window open. Drag your file onto the “Upload Data” window or browse and select the file. You have the option to select more than one file.

Step 4: When you have selected the file or dropped the file into the upload window, the UI will automatically upload the file and show the preview of the file. It looks like this:

1.3: Update the table details and convert the data types into Databricks Delta Lake format.
Once the file is uploaded by the UI, it shows the preview of the file. Here, we can do all the edits and data type conversions before creating the table.

Step 1: We can see the preview in ‘Vertical’ as well.

Step 2: In this window we can edit:

  • The details of the table such as ‘Name of the Table, Name of the Columns and select different schema’.
  • Different schema can be selected by clicking on the down arrow next to the “Default Schema”.
  • Table names can only contain lowercase alphanumeric and underscore, and must start with a lowercase letter or underscore.
  • Column names do not support commas, backslashes, or unicode characters (such as emojis). To edit the column name, click the input box at the top of the column.

Step 3: The “Data Types”.

Format options depend on the file format you upload. Common format options appear in the header bar and are inferred by default for CSV and JSON files. You can interpret all columns as STRING type by disabling “Advanced attributes > Automatically detect column types”.

For CSV, the following options are available:

  • First row contains the header (enabled by default): This choice determines if the CSV/TSV file includes a header.
  • Column delimiter: The column separator character must be a single character and cannot be a backslash. By default, CSV files use a comma as the separator.
  • Automatically detect column types (enabled by default): The file content is automatically analyzed to detect column types. You have the option to modify the types in the preview table. When this setting is disabled, all column types are assumed to be strings.
  • Rows span multiple lines (disabled by default): This option helps to identify each row in a file and span into multiple lines, rather than load all rows as a single row into a file.

Step 4: Once editing is completed, click on “Create Table” option on the bottom left to create the table. The table creates as per conditions and edits we have provided.
