### Search before asking - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. ### Paimon version paimon 0.9 ### Compute Engine Spark3.2.3 & Flink 1.18.1 ### Minimal reproduce step **Goal:** Multiple Spark jobs (60+) write to the same Paimon table in parallel. The partial-update feature is enabled, with each job updating only its own dedicated columns. The table property 'write-only' = 'true' is set. A dedicated compaction job is started to compact this table. ### What doesn't meet your expectations? **Problem:** Two jobs finished simultaneously, causing a snapshot conflict. During the doCommit phase: Job A acquired the snapshot ID 9793. It generated a snapshot temp file and then attempted to rename it to snapshot-9794. Concurrently, Job B, also in its doCommit phase, acquired the same latest snapshot ID 9793. It similarly generated a snapshot temp file and attempted to rename it to snapshot-9794. **Result:** The job that successfully performed the rename operation first (creating snapshot-9794) caused all updates from the other job to be lost. ### Anything else? _No response_ ### Are you willing to submit a PR? - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
