Configuring workflow scheduler¶
As of version 0.8, REANA supports two different workflow scheduling strategies:
fifo- first-in first-out strategy starting workflows as they come.
balanced- a weighted strategy taking into account existing multi-user workloads and the DAG complexity of incoming workflows.
By default REANA is configured to use
fifo workflow scheduler strategy.
If you would like to change it, you can configure
Helm value and set the desired strategy accordingly.
Note that it is also possible to change the workflow scheduler sleep time before re-inspecting
the workflow queue and launching new workflows. By default, REANA uses a sleep time of 15 seconds.
You can configure the Helm value
Please don't use values lower than 2 seconds; some delay is necessary for requeuing workflows in cluster overload situations.
