Data Analytics — VPC Flow Logs

This how-to guide shows you how to apply transformations to your VPC Flow Logs.

In our Data Ingestion How-to Guide for VPC Flow Logs, we showed how to load your data into SQLake, refine it, and prepare it for transformations. Below are a several examples of transformations you can apply to your refined data.
