9.3.5

QuestDB 9.3.5

Breaking changes 💥

• SAMPLE BY timezone bucket alignment: Sub-day SAMPLE BY queries with ALIGN TO CALENDAR TIME ZONE now produce correct bucket alignment during DST transitions. Key changes:
  • Sub-day buckets are uniformly spaced in UTC using the timezone's standard offset. During DST fall-back, repeated local hours produce separate rows instead of merging.
  • FROM/TO boundaries are now interpreted as local time in the specified timezone (previously UTC).
  • Queries without TIME ZONE, with fixed-offset timezones, or with super-day strides (day+) are unaffected.
  • See https://questdb.com/docs/query/sql/sample-by/#time-zone-transitions for details.

Highlights

Lateral joins

QuestDB now supports lateral joins, enabling subqueries in the FROM clause to reference columns from preceding tables. The implementation uses a decorrelation optimizer that transforms correlated subqueries into efficient set-based execution.

SELECT o.id, t.total
FROM orders o
JOIN LATERAL (
    SELECT sum(qty) AS total FROM trades WHERE order_id = o.id
) t;

LEFT LATERAL and implicit CROSS LATERAL are also supported:

SELECT o.id, t.qty
FROM orders o, LATERAL (SELECT qty FROM trades WHERE order_id = o.id LIMIT 3) t;

SQL-standard UNNEST

The new UNNEST operator expands array columns and JSON arrays into rows, enabling relational operations on array data:

-- Array expansion with position tracking
SELECT t.ts, u.price, u.pos
FROM trades t, UNNEST(t.prices) WITH ORDINALITY u(price, pos);
-- JSON object array extraction
SELECT u.price, u.name
</tr></table>
