5 questions in Storage Layout & Partitioning.

Quiz

A 4 TB events table serves three query patterns: 80% ask for one tenant over the last 7 days, 15% look up a single event by id, and 5% scan one product across all history. The table currently has no partitioning. Which layout should the team adopt?

A 6 TB events table is partitioned by `customer_id`. Queries are slow and the storage layer complains. What is wrong?

A new engineer asks why the 8 TB events table in the lakehouse has no index on customer_id when the same column is indexed in the operational Postgres the data came from. What is the actual reason?

A platform's analytical queries scan far more data than they need. Which storage layout decisions fix this?

An analytical query scans far more data than it needs. Before adding compute, what layout decisions should be examined?
