### Search before asking - [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar. ### Motivation For partitioned tables with Paimon lake tiering enabled, downstream batch jobs need a signal that a partition's data is "ready" (i.e., fully tiered). This is the **Mark Done** mechanism — when a partition has been idle (no new data tiered) for a configurable duration, Fluss should execute Paimon's mark-done actions (e.g., write `_SUCCESS` file, notify metastore) so downstream schedulers can safely begin processing. Currently, Fluss tiering operates at the table level with no partition-level idle tracking or mark-done capability. Paimon already has a complete mark-done action framework (`PartitionMarkDoneAction`), but its trigger mechanism is tightly coupled to Flink checkpoint lifecycle, which doesn't fit Fluss's tiering model. ### Solution Extend the Fluss offset file (V2) with: - `partition_tiered_times`: map of partitionId -> epoch millis of last tiering commit (wall-clock time, unaffected by compaction) ### Anything else? _No response_ ### Willingness to contribute - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
