High Cardinality Data in IIoT: Unlock Insights with InfluxDB

November 20, 2024

Managing Highly Contextualized Data for IIoT | SPONSORED

Have you ever wondered how industries using smart devices handle tons of unique data loading on their server?

High cardinality data allows for detailed tracking and monitoring of each sensor, machine, and device in real-time. Finding patterns and irregularities in this data type is necessary for interpreting large-scale, complex industrial processes. Each sensor has its own identity, location, and purpose, which are collected as tags and fields. Multiple values are the defining characteristic of high cardinality data. The diversity of data points produced by thousands of linked devices grows significantly as data collection ecosystems expand.

You can use high-cardinality data to improve productivity, streamline operations, and obtain in-depth insights. High cardinality includes more information, providing deeper and practical insights, which can optimize efficiencies, minimize downtime, and streamline inventory.

In this post, you will learn about the value of high cardinality data in the IIoT space. You will also be introduced to some of the challenges associated with this type of data, and how InfluxDB aims to solve them.

Understanding high cardinality data

Datasets with high cardinality have many unique values. These could include:

Identifiers in IIoT environments
Device IDs
Sensor serial numbers
Tags

Suppose you’re monitoring thousands of machines. Each one will have a distinct identification, and the data those machines provide—such as runtime hours or temperature readings—will change with time. The data has high cardinality because of its continual flow. High cardinality data is essential for jobs like predictive maintenance and in-depth analysis in industrial settings: it enables you to identify particular equipment or sensors and evaluate their performance.

The uniqueness of the data points differentiates high cardinality data from low cardinality data. Low cardinality data has fewer unique values, while high cardinality data involves many unique values (such as thousands of distinct sensor IDs).

An example of low cardinality data might be operational status, such as whether machines are on or off. Low cardinality provides more general knowledge, whereas high cardinality provides more specialized, in-depth insights. Both forms are useful in the context of IIoT, but high cardinality data enables more in-depth analysis and accurate decision making.

Use cases highlighting the importance of high cardinality data in IIoT

High cardinality data gives you in-depth insights into supply chain, inventory, sale, and maintenance management.

Predictive Maintenance

High cardinality data gives you visibility into hundreds or thousands of different sensors and devices. For instance, you can predict the likelihood of a failure by analyzing real-time data from many machine components. This allows you to minimize downtime and save money on repairs by performing maintenance only when necessary.

Asset Tracking and Management

In large industrial organizations, tracking multiple devices is simplified using high cardinality data. Because each asset is identified, you can easily manage and monitor its location, status, and usage in real-time. This is especially helpful in manufacturing and other businesses with extensive inventories, where accurate tracking can result in higher asset utilization and lower operating costs.

Energy Consumption Monitoring

High cardinality data is also essential for tracking energy consumption. Collecting time series data from several sources allows you to monitor energy use in multiple locations and devices. This lowers the cost of energy and increases sustainability in industrial processes by helping you identify inefficient patterns and implement optimization measures.

The role of high cardinality data in IIoT

High cardinality data is necessary in IIoT environments to improve performance and unlock better insights.

Enhanced Data Granularity

High cardinality data offers a complete understanding of specific hardware and operations. By collecting and analyzing data from multiple sources, you may improve supervision and make more informed decisions by closely monitoring the operation of particular devices or sensors.

Improved Anomaly Detection

High cardinality data is essential for detecting defects and identifying anomalous patterns in real-time. Because you’re doing fine-grained data analysis from multiple sources, it’s simpler to identify minor deviations or failure indicators before they become significant issues for the system.

Personalized Insights and Optimization

You can fine-tune optimizations for certain devices or actions with high cardinality data. More detailed data allows you to develop customized insights that boost reliability and performance so devices perform at peak efficiency while consuming the least amount of energy.

Challenges of managing high cardinality data in IIoT

The massive volume and complexity of data generated in IIoT systems makes managing high cardinality data extremely difficult. IIoT system performance, scalability, and general efficiency are impacted by all these issues.

Storage and Scalability Issues

Large volumes of high cardinality require a lot of data storage capacity. There’s an increasing need for scalable systems that can store and process data quickly without slowing down operations.

Data Query Performance

High cardinality data limits the query performance and makes real-time data retrieval and analysis challenging. It delays operational decision making because the results come from heavy searching over millions of unique IDs.

Increased Complexity in Data Management

High cardinality data management introduces additional levels of complexity. It’s difficult to efficiently organize and preserve this data without using a lot of resources since organizations have to deal with a range of data sources, formats, and levels of accuracy.

Cost of Infrastructure

A high-performing infrastructure and expensive instruments may be required to handle high cardinality data. The cost of advanced analytics tools, computing power, and data storage that are necessary for effective data management can greatly increase an organization’s costs.

Difficulty in Anomaly Detection

When there are so many different datasets, it becomes difficult to identify the exact root cause of an anomaly. High cardinality data sometimes increases the noise in datasets, making it more difficult to spot important patterns or anomalies in real-time data.

Data Privacy and Security Risks

Security concerns regarding sensitive data are also raised by high data volumes. High cardinality data is more prone to data breaches and data leakage issues, necessitating robust cybersecurity methods.
