What tables do we have related to customer orders?

discover_data

I found 3 assets matching "customer orders": the orders table in the warehouse, an orders_raw Kafka topic, and a daily_orders_summary view.

Who owns the orders table?

find_ownership

The orders table is owned by the Data Platform team. Sarah Chen is the primary contact.

What does "GMV" mean in the order_gmv column?

lookup_term

GMV stands for Gross Merchandise Value — the total sales revenue before deductions.

Less infrastructure, same power

Traditional data catalogs need an entire platform team. Marmot needs a database you probably already run.

Quick start

Deploy in under five minutes

Marmot runs as a single binary backed by PostgreSQL - the only dependency you need to start cataloging your data.
