# Panfactum Changelog — edge.24-06-20

> Introduces an alternative Kubernetes scheduler that significantly improves pod bin-packing for 25-33% cost reduction, adds integrated descheduling for underutilized nodes, and fixes Karpenter deployment issues.

## Highlights

- New [`kube_scheduler`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/kubernetes/kube_scheduler) for 25-33% node cost reduction via improved bin-packing
- New `panfactum_scheduler_enabled` input (default `false`) to opt in to the new scheduler per module
- Automatic descheduling of pods from low-utilization nodes when scheduler is enabled

## Additions

- Adds [`kube_scheduler`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/kubernetes/kube_scheduler), an alternative Kubernetes scheduler that improves pod bin-packing on nodes. Tests show an estimated 25-33% reduction in node
  - Impacts: iac-module `kube_scheduler` — New bin-packing scheduler for node cost reduction
- Adds `panfactum_scheduler_enabled` (default: `false`) input to most infrastructure modules. When enabled, uses the scheduler provided by [`kube_scheduler`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/kubernetes/kube_scheduler) instead of the
  - Impacts: iac-module `kube_scheduler` — New panfactum_scheduler_enabled opt-in input
- When `panfactum_scheduler_enabled` is `true`, the [`kube_descheduler`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/kubernetes/kube_descheduler) will automatically remove pods from low-utilization nodes for re-scheduling.
  - Impacts: iac-module `kube_descheduler` — Auto-evicts pods from low-utilization nodes

## Fixes

- Addresses a bug in the previous release that left [`kube_karpenter`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/kubernetes/kube_karpenter) undeployable.
  - Impacts: iac-module `kube_karpenter` — Fix for deployment failure from previous release
- Addresses an issue where nodes were limited to a hard cap of 29 pods.
- Configures Kubernetes nodes to use a fixed amount of system overhead rather than one that scales with node size.
