Give up committing. Don't panic! Conflicts during commits are normal and this failure is intended to resolve the conflicts. Conflicts are mainly caused by the following scenarios: 1. Multiple jobs are writing into the same partition at the same time, or you use STATEMENT SET to execute multiple INSERT statements into the same Paimon table. You'll probably see different base commit user and current commit user below. You can use https://paimon.apache.org/docs/master/maintenance/dedicated-compaction#dedicated-compaction-job to support multiple writing. 2. You're recovering from an old savepoint, or you're creating multiple jobs from a savepoint. The job will fail continuously in this scenario to protect metadata from corruption. You can either recover from the latest savepoint, or you can revert the table to the snapshot corresponding to the old savepoint. Base commit user is: 8c4e22ba-1553-4021-bbee-944764ce41aa; Current commit user is: 0ac35332-87ee-4f0e-8143-f5dac9e6d523 Base entries are: {kind=ADD,

BucketedAppendTable with OSS storage， 1. No other job is writing the table. 2. Some partition worked，but no new snapshot created (maybe no file meet the compaction condition?) . 3. Batch job started without savepoint. ### Anything else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
