ETL Builder supports major ETL operations such as:
- field selection
- row filtering
- sorting
- field management and calculated values
- expression-driven transforms
- spatial joins
- spatial grid and geometry stages
- custom logic stages
- multiple writer targets
Why preview matters
Tamaat's ETL user journey is intentionally preview-driven. Many stages can show users how the data changes before they run the entire flow. That reduces trial-and-error and helps users understand the impact of each stage while they build.
How to build a flow responsibly
- Add the reader first and validate the incoming fields.
- Add one transformation stage at a time.
- Use preview after each important stage instead of waiting until the end.
- Save and run manually before attaching a schedule.
What preview is doing for the user
Preview is not just a convenience. It is one of the main reasons the platform is easier to use. It helps users understand:
- which rows survive a filter
- how a field calculation changes values
- whether a join is behaving the way they expect
- whether a writer is receiving the data shape they intended
