# Avoid Primary Keys in Production!!! Use instead secondary indexes!

# Number of blocks by hour
```sql
SELECT COUNT(META().id) AS num, DATE_TRUNC_MILLIS(generated_time, 'hour') AS t
FROM `blockchain`
WHERE generated_time IS NOT NULL
GROUP BY DATE_TRUNC_MILLIS(generated_time, 'hour')
```

The where condition force to use generated_time index.
