----------------------------------
Summary: [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
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.
