Great question! So, what is elt? It’s basically ETL but with the T and L swapped. Instead of transforming data *before* loading, you dump it raw into your warehouse and transform it there.
Biggest perk? Speed. No waiting for transformations to finish before loading. Tools like Snowflake or BigQuery handle the heavy lifting.
Downside? If your target system sucks at transforming, you’re stuck. Also, messy raw data can be a headache later.
For tools, check out Fivetran or Stitch for ELT, and Talend for ETL.
