Polling for Models
The model poller runs periodically to pick up models that are ready for processing.
The XML files for each data model are initially located in the input folder. Based on the outcome of the processing, the models are moved to either the success bucket or the failure bucket and appropriate log messages and notifications are generated.
The model poller process is controlled by the following environment variables:
| Environment Variable | Description | Default Value |
|---|---|---|
| pollerInitialDelay | The delay (in milliseconds) after which the first polling iteration starts once the Model Loading Engine micro service starts running. | 60000
(60 seconds) |
| pollerFixedDelay | The delay (in milliseconds) between consecutive iterations of the polling process. Fixed delay environment variable controls how much gap in seconds needs to be added between two polling events. | 180000
(180 seconds) |
The model poller process is configured such that two iterations of the process start concurrently. The delay between two iterations is controlled by the pollerFixedDelay environment variable.
For example, the poller process starts at 10am and the model loading activity takes 10 minutes to complete, and the pollerFixedDelay is configured to be 3 minutes. The second iteration of the polling process will start at 10:13am, that is 3 minutes after the first iteration.
The number of threads used for processing models is controlled by the following flag that is configured using
