Augmented SQL for time series

QuestDB enhances ANSI SQL with time series extensions to manipulate time stamped data

SELECT timestamp, tempC
FROM sensors
WHERE timestamp = '2020-06-14;1M';

-- Search time
SELECT timestamp, tempC
FROM sensors
WHERE timestamp = '2020-06-14;1M';

SELECT timestamp, avg(tempC)
FROM sensors
SAMPLE BY 5m;

-- Slice time
SELECT timestamp, avg(tempC)
FROM sensors
SAMPLE BY 5m;

SELECT sensorName, tempC
FROM sensors
LATEST BY sensorName;

-- Navigate time
SELECT sensorName, tempC
FROM sensors
LATEST BY sensorName;

SELECT sensors.timestamp ts, rain1H
FROM sensors
ASOF JOIN weather;

-- Merge time
SELECT sensors.timestamp ts, rain1H
FROM sensors
ASOF JOIN weather;

Search Time

Filter and search for specific timestamps with “where”

Slice Time

Create time buckets and aggregate by intervals with “sample by”

Navigate Time

Search time series from most recent values to oldest with “latest by”

Merge Time

Join two tables based on timestamp where timestamps do not exactly match with “asof join”

Why time series?

DevOps monitoring

Collect metrics and events from your infrastructure (CPU, memory, networks, etc) and get real-time visibility into your entire stack.

Financial market data

Store market data to identify historical trends and correlations using statistical methods and generate trading signals.

Connected devices

Capture, store and respond to data from sensors at any resolution in industrial applications.

Application metrics

Empower users of your application to track and visualise logs, api calls and any application activity in real-time.

CRUD for time series

Allows easy changes in historical data through fully ACID support for CRUD APIs.

Integrated data

Pull together all your application, device, and infrastructure data for a complete, 360º view of all aspects of your business.

Interactive Console

Interactive console to import data (drag and drop) and start querying right away. Check our Web Console guide to get started.

Artistic view of QuestDB's Web Console split in 3 components: the navigation tree, the SQL code editor and data displayed as a chart

Postgres wire support

Interact with QuestDB using the Postgres wire and any tool that connects to it.
