Scheduling
...
We distinguish two types of schedulers namely Basic and Advanced. Choosing the right scheduler that suits your needs depends on the business demands and the number of cases and tasks being processed. The paragraphs below describe the workings of both schedulers and the considerations when choosing the appropriate one.

By default Blueriq uses the basic a scheduler for evaluating tasks and priorities. The evaluating evaluation is executed according to the configuration of the blueriq.timer.interval. This can be set to hourly (default) or , each minute or never. Each time the interval expires, the process engine starts evaluating each available project all projects present on the Runtime that uses are using the Process Engine.

. Per project all cases are retrieved that contain timer tasks, automatic tasks, tasks with a expiration date or Priority Algorithms. When the evaluation leads to a match (meaning when the current time matches the proposed execution time), the task is executed.
As a result, in a single-node or multi-node (clustered) environment when the interval expires, one of the nodes will start evaluating all projects which in turn will cause a peak load due to the increase CPU and memory consumption of that specific node.
