I am building an event-based monitoring system using GridDB. The goal is to trigger alerts when specific conditions are met in time-series data. For example:

• If a value exceeds a threshold for more than 5 consecutive minutes, an alert should be triggered.

Current Setup:

The data is stored in a TimeSeries container with the schema:

• timestamp (TIMESTAMP)
• sensor_id (STRING)
• value (DOUBLE)

What I Tried:

1. Periodic Queries: Used Python to poll data at regular intervals and check conditions, but this approach is inefficient.
2. Manual Processing: Retrieved all data and checked for threshold breaches in Python, which is not scalable.

My Question:

• Does GridDB provide a native mechanism for event-based triggering or alerting?
• If not, how can I efficiently implement a custom solution to detect and respond to threshold breaches in real time?
