What's a kubernetes StatefulSet?
3 min read
When we need to have a stateful application running on Kubernetes, we might need to use a StatefulSet. With a StatefulSet, we can manage stateful applications where each pod needs a stable, unique network identity and storage that persists across pod rescheduling. Unlike Deployments, which focus on maintaining a specified number of replicas, StatefulSets ensure each pod is given a unique ordinal index and retains the same identity throughout its lifecycle. If a pod is deleted or a node fails, the replacement pod will maintain the same identity and storage.

Go is a garbage-collected language: It will reclaim any unused memory. This automation can sometimes introduce performance challenges. We can use the GODEBUG environment variable to provide insights into specific internal operations of the Go runtime, such as scheduling, memory allocation, and garbage collection.
