FAQs

What is ETL?

ETL, an acronym for Extract, Transform, Load, is a vital data integration process. It involves extracting data from diverse sources, transforming it into a usable format, and loading it into a database, data warehouse or data lake. This process enables meaningful data analysis, enhancing business intelligence.

What is Azure Blob Storage?

What data can you extract from Azure Blob Storage?

Azure Blob Storage's API provides access to various types of data, including:
1. Unstructured data: This includes any type of data that does not have a predefined data model or structure, such as text, images, videos, and audio files.
2. Structured data: This includes data that has a predefined data model or structure, such as tables, columns, and rows.
3. Semi-structured data: This includes data that has some structure, but not enough to fit into a traditional relational database, such as JSON, XML, and CSV files.
4. Metadata: This includes information about the data stored in Azure Blob Storage, such as file size, creation date, and last modified date.
5. Access control data: This includes information about who has access to the data stored in Azure Blob Storage and what level of access they have.
6. Logging data: This includes information about the activities performed on the data stored in Azure Blob Storage, such as read and write operations, and access attempts.Overall, Azure Blob Storage's API provides access to a wide range of data types, making it a versatile and flexible storage solution for various types of applications and use cases.

How do I transfer data from Azure Blob Storage?

This can be done by building a data pipeline manually, usually a Python script (you can leverage a tool as Apache Airflow for this). This process can take more than a full week of development. Or it can be done in minutes on Airbyte in three easy steps:
1. Set up Azure Blob storage to ClickHouse as a source connector (using Auth, or usually an API key)
2. Choose a destination (more than 50 available destination databases, data warehouses or lakes) to sync data too and set it up as a destination connector
3. Define which data you want to transfer from Azure Blob storage to ClickHouse and how frequently
You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud.

What is ELT?

ELT, standing for Extract, Load, Transform, is a modern take on the traditional ETL data integration process. In ELT, data is first extracted from various sources, loaded directly into a data warehouse, and then transformed. This approach enhances data processing speed, analytical flexibility and autonomy.

Difference between ETL and ELT?

ETL and ELT are critical data integration strategies with key differences. ETL (Extract, Transform, Load) transforms data before loading, ideal for structured data. In contrast, ELT (Extract, Load, Transform) loads data before transformation, perfect for processing large, diverse data sets in modern data warehouses. ELT is becoming the new standard as it offers a lot more flexibility and autonomy to data analysts.
