> [K8s] More efficient storage of executor pod state
> --------------------------------------------------
>
> Key: SPARK-24584
> URL: https://issues.apache.org/jira/browse/SPARK-24584
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes
> Affects Versions: 2.4.0
> Reporter: Matt Cheah
> Priority: Major
>
> Currently we store buffers of snapshots in {{ExecutorPodsSnapshotStore}},
> where the snapshots are duplicated per subscriber. With hundreds or maybe
> thousands of executors, this buffering may become untenable. Investigate
> storing less state while still maintaining the same level-triggered semantics.
