What is a time series?
Wikipedia defines a time series as, “A series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time.”

Examples of time series?

  • The temperature of a home during a day
  • Position of a satellite during a day

The data in these examples constitute a monitored value (e.g. temperature or position) corresponding to the time at which the reading of the value took place. 

What is TimescaleDB?
TimescaleDB is an open-source database designed to make SQL scalable for time series data. TimescaleDB is packaged as a PostgreSQL extension and released under the Apache 2 open-source license.

How to use TimescaleDB in Aiven PostgreSQL

1. Connect to the Aiven PostgreSQL (Master) instance with PostgreSQL version 10.3 or later

Using your favorite PostgreSQL client (e.g., psql, DBeaver, PSequel, etc) connect to Aiven PostgreSQL instance

2. Create the TimescaleDB extension


3. Create a time series table to store time series data

CREATE TABLE location_condition (
  time        TIMESTAMPTZ       NOT NULL,
  location    TEXT              NOT NULL,

SELECT create_hypertable('location_condition','time');

4. Ingest time series data into TimescaleDB in Aiven PostgreSQL

INSERT INTO location_condition(time, location, temperature, humidity) VALUES (NOW(), 'office', 70.0, 50.0);
