What is ELT? Extract, Load, Transform | Confluent [Video]

Benefits of ELT: When should I use ELT?

Just like ETL, ELT is best when it comes to the following use cases:

When real-time and instant access is non-negotiable

ELT works best for real-time analysis since the data is received directly from the source and loaded immediately into the storage. This way, organizations can instantly access the data and push it for various business intelligence reports for real-time data processing and reporting.

Real-time data processing is required

For some analytics projects, real-time data processing and analytics are necessary. ELT is the way to go for these options because of its low latency, ability to handle large volumes of data, and various data formats.

Flexibility in data transformation

Since transformation occurs after loading into the database, you can transform it based on the use case requirement. This removes the required upfront transformation, as transformation does not need to be fully defined as data extraction.
