= Optional: Configuring polling operations for NUMA resources updates
The daemons controlled by the NUMA Resources Operator in their `nodeGroup` poll resources to retrieve updates about available NUMA resources. You can fine-tune polling operations for these daemons by configuring the `spec.nodeGroups` specification in the `NUMAResourcesOperator` custom resource (CR). This provides advanced control of polling operations. Configure these specifications to improve scheduling behaviour and troubleshoot suboptimal scheduling decisions.

[NOTE]
====
`podsFingerprinting` is enabled by default. `podsFingerprinting` is a requirement for the `cacheResyncPeriod` specification in the `NUMAResourcesScheduler` CR. The `cacheResyncPeriod` specification helps to report more exact resource availability by monitoring pending resources on nodes.
The default value for `podsFingerprinting` is `EnabledExclusiveResources`. To optimize scheduler performance, set `podsFingerprinting` to either `EnabledExclusiveResources` or `Enabled`. Additionally, configure the `cacheResyncPeriod` in the `NUMAResourcesScheduler` custom resource (CR) to a value greater than 0. The `cacheResyncPeriod` specification helps to report more exact resource availability by monitoring pending resources on nodes.
