dybyte opened a new pull request, #11244:
URL: https://github.com/apache/seatunnel/pull/11244
### Purpose of this pull request
This PR excludes `engine_runningJobMetrics` from persistent IMAP storage.
`engine_runningJobMetrics` stores high-frequency runtime metrics snapshots
used for observability. Persisting this map through the generic `map.engine*`
`map-store` configuration causes unnecessary WAL growth and write
amplification, while providing limited recovery value compared with
authoritative engine state.
This change keeps the existing `map-store` behavior for other engine maps,
but skips persistence initialization for the runtime metrics snapshot map.
### Does this PR introduce _any_ user-facing change?
Yes.
When IMAP persistence is enabled through `map.engine*`,
`engine_runningJobMetrics` is now intentionally excluded from persistent
storage. This changes persistence behavior for runtime metrics snapshots and
reduces WAL growth for observability-only state.
The deployment documentation was also updated in both English and Chinese to
clarify this behavior.
### How was this patch tested?
- Added a unit test in `FileMapStoreTest` to verify that:
- `engine_runningJobMetrics` skips persistent storage initialization
- it does not fail even when the configured storage type is invalid
- store/delete/load operations remain safe as no-op behavior
