The ELT process has modernized data pipelines, fastened your data loading speed, and facilitated efficient data analysis. 

However, there is still a delay in the analysis and the time to obtain reports and insights, as your analysts have to run a few additional data transformation jobs at the warehouse to clean and format the data.

This is because the data loaded into the warehouse may not be consistent, organized, and per the data warehouse tables format. 

If you eliminate these additional data transformation jobs at the data warehouse, you will accelerate your analytics. All you need is a method to format and clean the data before loading it to the warehouse. 

Thus, we innovated and launched an Inflight Transformation on Hevo’s ELT Pipelines, where data teams can perform lightweight data transformation inflight. 

What is Inflight Transformation?

Inflight transformation is an ELT data pipeline feature innovated by Hevo, i.e., implementing lightweight data transformation within the pipeline before loading the data to the warehouse.

Hevo’s Inflight Transformation cleans, enriches, and standardizes data on the fly without impacting the load performance of the pipeline.

We believe inflight transformation should be essential in your modern ELT data pipelines. It enables your data teams to effortlessly maintain a consistent data format at the warehouse.

4. JSON Normalization

5. Clean and Filter Events

There are a few events or fields that you would not want to load to your warehouse. You can filter out such fields or events in the pipeline itself. For example, filtering out all the canceled orders from your sales dataset. 

Here is an example of how Inflight Transformation boost ELT data pipelines

Consider a global e-commerce company with multiple versions of their website like .us, .au for each location. They want to build a dashboard to analyze accumulated and region-wise traffic on each product page. 

They would need to load the data for each region from Google Analytics to their data warehouse while adding the respective location name for each record. This can be easily achieved by creating a pipeline with inflight transformation each property on Google Analytics. 

Hevo's Inflight Transformation-Example

Using Inflight Transformation on Hevo, they can add a field ‘Country’ and populate it with the respective country name for each region. For a pipeline loading data from .au, they can set the rule to add a new field ‘Country’ with populated value ‘Australia’. 

With this, analysts will have access to complete data of website traffic for each region with their respective location names in the data warehouse. Thus, they can directly run queries to build a dashboard for product pages while adding country as a dimension.
