Includes new partitions, improved data upload process, added an automatic recovery process, other upgrades, and fixes.
Enhancements and Improvements
(This section describes enhancements and improvements added for Rekor Discover.)
- Partitioned several large database tables, significantly improving performance. The partitioning also increases Discover's PVR ingestion capacity and simplifies data management tasks like archiving and maintenance, which will be further enhanced in a future release with the implementation of data retention policies.
- Updated the data upload process to the MS2 traffic data integrator to support real-time uploads.
- Introduced an automatic recovery feature for devices. If a PVR heartbeat is not received from a device for 30 continuous minutes, Discover will automatically attempt to resolve the issue by restarting the STS container on the device. This restart will occur at most once per day, helping to ensure that data is not held up before being sent to Drakewell.
- Upgraded from Java 17 to Java 21 and Spring Boot 2 to Spring Boot 3 which has enhanced support for database partitioning and improves performance, concurrency, and scalability.
Known Issues
(This section describes fixes, known issues, and suggested work arounds for Rekor Discover.)
-
Resolved an issue where the CSV volume totals exported from the Speed and Classification Report included data from all study stations, rather than only those selected for the report.
-
Fixed an issue in Device Calibration where users were unable to modify the Average Length of Lane Markers when selecting 'Various Markings.' Attempts to change the value using the arrows or by typing would revert back to the original value in the JSON. Users can now successfully update the Average Length of Lane Markers as intended.
