HeartSaVioR opened a new pull request #25811: [SPARK-29111][CORE] Support snapshot/restore on KVStore URL: https://github.com/apache/spark/pull/25811 # What changes were proposed in this pull request? This patch is a part of SPARK-28594 and design doc for SPARK-28594 is linked here: https://docs.google.com/document/d/12bdCC4nA58uveRxpeo8k7kGOI2NRTXmXyBOweSi4YcY/edit?usp=sharing This patch proposes adding new feature to KVStore, snapshot (dump) & restore. The structure of snapshot file is also described to the design doc, but it's alike the structure of delta/snapshot file in HDFSBackedStateStoreProvider. ### Why are the changes needed? The new feature will be used as a building block for [SPARK-28870](https://issues.apache.org/jira/browse/SPARK-28870) and possibly be used for [SPARK-28867](https://issues.apache.org/jira/browse/SPARK-28867) as well. The patch is intended to be separate with these issues, as I would like to make each PR smaller, and both downstream issues can be worked concurrently after this patch. ### Does this PR introduce any user-facing change? No, as KVStore interface is defined as `@Private`. ### How was this patch tested? Added new UTs.
