## Table sample

<TableSample tableSchema="gas" tableName="fees" />

## Query performance

Partition keys: `blockchain`, `block_month`, `block_date`. Always include `blockchain` and a date filter.

```sql theme={null}
-- ✅ Good: chain + date filter
SELECT * FROM gas.fees
WHERE blockchain = 'ethereum'
  AND block_date = CURRENT_DATE
```
