Worked on the percona/percona-server-mongodb-operator repository to deliver an External Volume Autoscaling configuration option within the PerconaServerMongoDB custom resource. This feature, implemented using Go and YAML, allows the operator to suppress storage discrepancy errors and ignore PersistentVolumeClaim reconciliation when external autoscaling is enabled. By disabling automatic volume resizing for externally managed volumes, the solution prevents conflicts with external autoscalers and reduces operational noise in cloud native environments. The approach focused on operator development best practices, ensuring reliability and clear traceability through targeted commits. No bugs were fixed during this period, with efforts concentrated on this feature’s robust implementation.
