Extraction: The ETL process initiates by retrieving raw data from diverse sources, such as databases, applications, or other platforms.The ETL process of late is increasingly being replaced by the ELT (Extract Load Transform) process where the data transformation takes place on the data warehouse itself after loading, using the immense compute power of the data warehouse rather than stressing the source systems. It also enables security checks and privacy controls while integrating data. Why You Need Snowflake StagesĮTL provides rapid data integration, sometimes in real-time if required, and is ideal for legacy systems. It involves setting up of ETL pipelines to integrate data from different sources, typically into a staging area where it can be prepared and converted into a consumable format and then loaded into a data warehouse or data repository for data analytics, machine learning, or just storage. The ETL (Extract Load Transfer) process we know has been around a long time now. Zero-ETL and traditional ETL (whether manual or automated) are different animals. Successful Data Ingestion (What You Need to Know) Traditional ETL is very different from Zero-ETL It is a simpler, almost instant method of data transfer that does not involve cleaning or modification of data. Traditional processes use Extract Transform Load processes to move data from one system to another whereas Zero-ETL directly moves the data from one system to another, where it can be queried without time-consuming transformation. It is a data integration of sorts that moves away from the traditional construct of ETL (Extract Transform Load). As a process, Zero-ETL is really Zero-EL, the transformation phase is done away with. So, you want to go Zero-ETL? Not so fast! Zero-ETL may be the shiny new thing in the data science world but is it appropriate for you? Let’s look at what Zero-ETL really implies. Traditional ETL is very different from Zero-ETL.What is Zero-ETL, and how is it different from traditional ETL? How does Zero-ETL integration work, and which data patterns can be considered to be part of the Zero-ETL universe? Besides answering these questions, we also look at the benefits and drawbacks of Zero-ETL, and how BryteFlow as a Zero-ETL replication tool seamlessly automates the data integration process. Zero-ETL and its role in data integration is the topic of this blog.
