What is MariaDB?

MariaDB is an open-source relational database management system (RDBMS) that was created as fork of MySQL. It is developed by the original developers of MySQL. It is designed to offer enhanced performance, improved scalability and data processing capabilities. It maintains its compatibility with MySQL.

Features of MariaDB

• MySQL Compatibility: It was designed to be fully compatible with MySQL, so the migration from one to another is pretty easy without major application or data changes.
• High Performance and Scalability: MariaDB is designed to efficiently serve hundreds of millions of records. It’s replication, and multiple storage engines enable MariaDB to scale as your application does.
• Security and Flexibility: Some of the advanced security features in MariaDB include encryption and user roles. Advanced SQL functions support complex queries and give you enormous flexibility in managing your data.

What is DataBricks?

Databricks is a cloud-based platform that helps companies manage and analyze big data using tools like Apache Spark. It simplifies the process of setting up and running data pipelines, allowing businesses to quickly make sense of large amounts of data and turn it into useful insights.

Features of Databricks 

• Unified Data Platform: Databricks combines data engineering, data science, and machine learning into one place so teams can work together easily.

• Scalable: It can handle both small and huge data workloads, growing with your business as needed, without the hassle of managing servers.

• Integration: Databricks integrates well with cloud platforms like AWS, Azure, and Google Cloud, and also works with popular data storage systems like Snowflake, SQL databases, and data lakes.

Method 1: Automate the Data Replication process using Hevo

Step 1: Configure MariaDB as a Source

Authenticate and Configure your MariaDB Source.

Step 2: Configure Databricks as a Destination

In the next step, we will configure Databricks as the destination.

Once your MariaDB to Databricks ETL Pipeline is configured, Hevo will collect new and updated data from MariaDB every five minutes (the default pipeline frequency) and duplicate it into Databricks. Depending on your needs, you can adjust the pipeline frequency from 5 minutes to an hour.

In a matter of minutes, you can complete this No-Code & automated approach of connecting MariaDB to Databricks using Hevo and start analyzing your data.

Method 2: Replicate Data from MariaDB to Databricks Using CSV

To start replicating data from MariaDB to Databricks, firstly, you need to export data as CSV files from MariaDB, then import the CSV files into Databricks and modify your data according to the needs.

Step 1: Export the database as CSV from MariaDB

Below is the command in general format to export your data

Select field from table_name
INTO OUTFILE '/path/to/save/filename.csv'
FIELDS ENCLOSED BY ''
TERMINATED BY ','
ESCAPED BY '"'
LINES TERMINATED BY '\n';

Step 2: Create a Table in Databricks by Uploading CSV Files

In the Databricks UI, use the sidebar menu to find data and create a table either by browsing your files from the local computer or dragging your CSV files into the drop zone.

Your path will look something like this:

/FileStore/tables/<fileName>-<integer>.<fileType>

Once uploaded, you can simply view your data by clicking the Create Table with UI button.

Step 3: After you upload the CSV data to Databricks, you can read and modify the data.

• To preview a cluster, click on the Preview Table after selecting it. Databricks now lets you read your CSV data.

• In Databricks, data types are string by default. You can choose the data type from a list of options.

• The left navigation bar can help you modify the data easily. To create a table, click the “Create Table” button on the left navigation bar.
• Once all the table settings have been configured, click the “Create Table” button to finish.

The CSV files can be accessed from the cluster where you have stored that file.

This 3-step process using CSV files is a great way to effectively replicate data from MariaDB to Databricks. It is optimal for the following scenarios:

• One-Time Data Replication: When your marketing team needs the MariaDB data only once in a long period of time. 
• No Data Transformation Required: If there is a negligible need for data transformation and your data is standardized, then this method is ideal. 

In the following scenarios, using CSV files might be cumbersome and not a wise choice:

• Data Mapping: Only basic data can be moved. Complex configurations cannot take place. There is no distinction between text and numeric values and null and quoted values.
• Frequent changes in Source Data: To achieve two-way synchronization, the entire process must be run frequently to access updated data on the destination. 
• Time Consuming:  If you plan to export your data frequently, the CSV method might not be the best choice since it takes time to recreate the data using CSV files.
