# Support independent PVC retention policies (whenDeleted/whenScaled) in
SolrCloud deployments
**Is your feature request related to a problem?**
In Kubernetes 1.27+ a new feature was added where a retention policy can be
used to control if and when PVCs created from a StatefulSet's
`volumeClaimTemplate` are deleted.
The Apache Solr Operator currently does not expose the StatefulSet
`persistentVolumeClaimRetentionPolicy` feature through the SolrCloud CRD
configuration. The operator only provides basic PVC management through
`dataStorage.persistent.reclaimPolicy`, which applies the same policy to both
deletion and scaling scenarios.
**Describe the solution you'd like.**
The ability to configure `whenDeleted` and `whenScaled` policies
independently through the SolrCloud CRD:
```yaml
# Current limitation:
spec:
dataStorage:
persistent:
reclaimPolicy: "Retain" # Same for both scenarios
# Desired configuration:
spec:
dataStorage:
persistent:
reclaimPolicy:
whenDeleted: "Retain" # Keep PVCs during maintenance
whenScaled: "Delete" # Clean up PVCs during scaling
```
This would generate the appropriate StatefulSet
`persistentVolumeClaimRetentionPolicy` configuration.
**Describe alternatives you've considered.**
Manual StatefulSet patching works but is overwritten during AroCD sync's
Kustomize overlays are overwritten during deployment.
**Additional context.**
**Environment:** Enterprise Kubernetes (AKS) with GitOps using ArgoCD and
Kustomize
**Use Case:** Need different retention behaviors for maintenance workflows
(retain data) vs dynamic scaling operations (cleanup for cost optimization).
**Precedent:** This feature has been implemented in other Helm charts:
- [[Prometheus community charts (Issue
#3711)](https://github.com/prometheus-community/helm-charts/issues/3711)](https://github.com/prometheus-community/helm-charts/issues/3711)
- [[Bitnami Solr chart (PR
#33272)](https://github.com/bitnami/charts/pull/33272)](https://github.com/bitnami/charts/pull/33272)
**Backward Compatibility:** Existing `reclaimPolicy` string format should
continue working to set both policies to the same value.
