Piotr Nowojski updated FLINK-26147:
-----------------------------------
Summary: Incremental savepoints directory in CLAIM mode is not being
deleted (was: Deleting incremental savepoints directory in CLAIM mode)
> Incremental savepoints directory in CLAIM mode is not being deleted
> -------------------------------------------------------------------
>
> Key: FLINK-26147
> URL: https://issues.apache.org/jira/browse/FLINK-26147
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Checkpointing
> Affects Versions: 1.15.0
> Reporter: Piotr Nowojski
> Priority: Major
>
> Native format supports incremental RocksDB savepoints. For those savepoints
> Flink puts all SST files inside the savepoints directory. This means such
> savepoints are self-contained and relocatable. However, when restored in
> CLAIM mode, subsequent checkpoints might reuse some SST files, which in turn
> might block deleting the savepoints directory at the time the savepoint is
> subsumed. Later on Flink will delete the reused shared SST files, but it
> won’t retry deleting the savepoints directory. Therefore, it is possible
> Flink leaves an empty savepoints directory if it was restored in CLAIM mode.
> We should find a way to clean up that left over directory.
