IoT Database

CrateDB is an open source, multi-model and distributed database that offers high performance, scalability and flexibility. Accelerate your IoT projects and get real-time insights into high-volume IoT data. You can store any type of data - both structured, semi-structured and unstructured - and  leverage native SQL to query the data, as well as advanced time-series and search functionalities.

Sensor data queries with SQL

Hyper-fast. Results in milliseconds.

 

        

/* Based on IoT devices reports, this query returns the voltage variation over time
for a given meter_id */ WITH avg_voltage_all AS ( SELECT meter_id, avg("Voltage") AS avg_voltage, date_bin('1 hour'::INTERVAL, ts, 0) AS time FROM iot.power_consumption WHERE meter_id = '840072572S' GROUP BY 1, 3 ORDER BY 3 ) SELECT time, (avg_voltage - lag(avg_voltage) over (PARTITION BY meter_id ORDER BY time)) AS var_voltage FROM avg_voltage_all LIMIT 10;

Data interoperability

CrateDB offers data collection and storage for any type of data source: sensor data, historical data, geospatial data, operational parameters, environmental conditions ...

You can store complex objects in the database, before even knowing how you want to model your data. You can also add new data types and formats on the fly, thanks to dynamic schema capabilities. There is no need for human intervention and and no need to synchronize multiple databases.

Scalability and performance

With CrateDB, data is available for query instantly after data ingestion. You get response-time in milliseconds - even for complex ad-hoc queries across billions of records - thanks to a fully distributed query engine. This gives you real-time insights and responsiveness.

CrateDB computes data aggregations on the fly thanks to columnar storage. There is no need to downsample or pre-aggregate the data.

To meet the stringent requirements of industrial environments, CrateDB can scale easily. This way, you can cope with the huge volumes of IoT data continuously flowing from different sources.

Time-series

CrateDB has all the features of an advanced time-series database. This includes instant access to years of data, thanks to a distributed architecture with efficient sharding and partitioning mechanisms.

CrateDB also provides efficient storage, and instant querying of time stamped data to enable trend analysis, forecasting, and historical comparisons.

Fault tolerance built-in

CrateDB has built-in data replication and cluster rebalancing mechanisms. This provides fault tolerance and high availability for 24/7 operations.

Easy and seamless integrations

CrateDB offers a seamless integration with popular IoT stack software such as Kafka, Grafana, Node-RED, and more. It uses for that native SQL and the PostgreSQL Wire Protocol.

Drivers and libraries are available for many programming languages, as well as a REST API.

Edge computing

IoT projects often require a deployment at the Edge and in the cloud to enable real-time decision-making and analytics in various connectivity scenarios.

CrateDB effectively addresses this need by offering an IoT database with multiple deployment options. It supports both on-premises, Edge, and cloud environments.

A Docker container can be deployed on Edge devices and data can be synchronized with other clusters thanks to logical replication.

Digital twins

CrateDB offers a unique repository to store and retrieve metadata associated with digital twins. This includes information about the physical entity, data sources, data quality and modeling assumptions.

Time-series data can be contextualized with this information in real-time. An easy switch can be made from a technical view to a business view.

Integration with data analytics and AI technologies make it fluid to run complex algorithms, machine learning models, and statistical analysis directly on the stored data. 

Open source

CrateDB open source licensing model reduces your IT costs and provides the support of an active community.

Whether you want to get everything managed for you with the SaaS model or prefer deploy the product yourself, we have the right option for you if you decide to go for a fast and scalable IoT database. 

Our customers might have a hundred of different vessels navigating in the seas with limited connectivity, so we actually need to work quite much both at the Edge and the Cloud.

IoT Device Integration with Python

        

# Send IoT data to CrateDB with a simple HTTP request

import requests
import json

from datetime import datetime

def send_iot_data(device_id, temperature, humidity):

    url = "http://localhost:4200/_sql"
    headers = {'Content-Type': 'application/json'}
    payload = {

        "stmt": "INSERT INTO iot_data (device_id, temperature, humidity)
        VALUES ('{device_id}', {temperature}, {humidity})"
    }

    response = requests.post(url, headers=headers, data=json.dumps(payload))

    if response.status_code == 200:
        print("Data sent successfully!")
    else:
        print(f"Error sending data. Status code: {response.status_code}")

# Example Usage

send_iot_data('device-3', 22.5, 58.3)
        
        
        

Talk - Not All Time-Series are Equal

This talk at the IoT Tech Expo 2023 explores the complexities of industrial big data, characterized by its high variety, unstructured features, and different data frequencies. It also analyzes how these attributes influence data storage, retention, and integration when dealing with an IoT database.

In the world of Internet of Things, managing the volume, variety, and speed of data collected is a constant challenge. With its fast data ingestion, versatile data modeling, and real-time querying capabilities, CrateDB helps businesses harness the full value of high-volume data from thousands of IoT sensors.

Traditional IoT database systems frequently struggle to keep up with the massive volumes of data generated by thousands of sensors. CrateDB overcomes this challenge by providing fast, scalable data ingestion, processing millions of IoT data points per second. It indexes and makes data available for query in real-time. This enables businesses to achieve real-time monitoring, improved operational efficiency, and faster decision-making.

Another challenge is to connect data with digital twins, which offer a way to bridge the gap between the physical and digital worlds. Whether it’s for predictive maintenance, smart building solutions, data driven energy transition or raw material waste reduction, digital twins offer huge potential to improve operational efficiency and position enterprises for future growth. CrateDB significantly enhances the effectiveness and capabilities of digital twin implementations. For that, it executes complex ad-hoc queries very fast, reduces development efforts and optimizes total cost of ownership.

Use cases: successful companies adopting an IoT database

"Working with CrateDB brings positive outcomes. The ingestion and throughput have very good performance, with 1 million values/sec, the horizontal scalability where we can add as many nodes as we need and the automatic query distribution across the whole cluster."

Data comes in many different formats. With our digital twin application, users can correlate different data series to perform detailed error analysis. Every time there is a high error rate, users can go back in time, see all relevant machine data and draw their conclusions on how to avoid errors in the future.
