Monthly updates from the QuestDB team with a deep dive into QuestDB 6.4, Redpanda integration, MindsDB joint-webinar, community updates, and more.

QuestDB 6.4#

We just shipped QuestDB 6.4! This version includes the long-awaited SQL UPDATE statement (docs), which allows users to modify already-written records in QuestDB.

Update with constant
UPDATE trades SET price = 125.34 WHERE symbol = 'AAPL';
Update with function
UPDATE book SET mid = (bid + ask)/2 WHERE symbol = 'AAPL';

Here is a blog post that explains why UPDATE matters for time-series databases: QuestDB 6.4

Query benchmark vs Clickhouse and Timescale#

Our engineering team just published a new benchmarking article, in which we compare QuestDB with other time-series databases and publish the results. This benchmark comes on the back of QuestDB's new JIT (Just-in-Time) compiler and multi-threaded execution for filter queries.

With this performance, scanning through billions of records without the need of building indexes becomes a reality.

Integration with Redpanda#

A new tutorial is published by our contributor, Yitaek Hwang, together with the Redpanda team.
