Key use cases for YugabyteDB and BigQuery integration

YugabyteDB’s Change Data Capture (CDC) with BigQuery serves multiple essential use cases. Let’s focus on two key examples.

1. Industrial IoT (IIoT): In IIoT, streaming analytics is the continuous analysis of data records as they are generated. Unlike traditional batch processing, which involves collecting and analyzing data at regular intervals, streaming analytics enables real-time analysis of data from sources like sensors/actuators, IoT devices and IoT gateways. This data can then be written into YugabyteDB with high throughput and then streamed continuously to BigQuery Tables for advanced analytics using Google Vertex AI or other AI programs.

Examples of IIoT Stream Analytics

BigQuery can process and analyze data from industrial IoT devices, enabling efficient operations and maintenance. Two real-world examples include:

  • Supply chain optimization: Analyze data from IoT-enabled tracking devices to monitor inventory, track shipments, and optimize logistics operations.
  • Energy efficiency: Analyze data from IoT sensors and meters to identify energy consumption patterns to optimize usage and reduce costs.

2. Equipment predictive maintenance analytics: In various industries such as manufacturing, telecom, and instrumentation, equipment predictive maintenance analytics is a common and important use case. YugabyteDB plays a crucial role in collecting and storing equipment notifications and performance data in real time. This enables the seamless generation of operational reports for on-site operators, providing them with current work orders and notifications.

Maintenance analytics is important for determining equipment lifespan and identifying maintenance requirements. YugabyteDB CDC facilitates the integration of analytics data residing in BigQuery. By pushing the stream of notifications and work orders to BigQuery tables, historical data accumulates, enabling the development of machine learning or AI models. These models can be fed back to YugabyteDB for tracking purposes, including failure probabilities, risk ratings, equipment health scores, and forecasted inventory levels for parts. This integration not only enables advanced analytics but also helps the OLTP database (in this case, YugabyteDB) store the right data for the site engineers or maintenance personnel in the field.

So now let’s walk through how easy it is to integrate YugabyteDB with BigQuery using CDC.
