----------------------------------
Summary: There may be a risk of data loss when two jobs write to
the same Paimon table concurrently
Key: FLINK-38478
URL: https://issues.apache.org/jira/browse/FLINK-38478
Project: Flink
Issue Type: Bug
Components: Flink CDC
Affects Versions: cdc-3.5.0, cdc-3.4.0, cdc-3.2.1, cdc-3.3.0, cdc-3.1.1,
cdc-3.2.0, cdc-3.1.0
Reporter: Yanquan Lv
When two jobs write to the same Paimon table concurrently, using the same
*commit user* and *commit identifier* may result in data loss. Currently, the
commit user must be explicitly specified in the job.
To resolve this issue, we can modify the system to automatically generate a
random *UUID* for each commit, ensuring uniqueness and avoiding conflicts.
