<!-- code-pr-reviewer -->
Thanks for reporting this. I can confirm this is a valid bug affecting the
SelectDB connector in version 2.3.12 when running with the Zeta engine.
The root cause is that `SelectDBConfig` does not implement
`java.io.Serializable`, which causes a `NotSerializableException` when
Hazelcast attempts to serialize the `SinkAction` containing `SeaTunnelSink`
during distributed execution. This issue was introduced in 2.3.12 and affects
jobs using 2PC mode or other scenarios requiring distributed serialization.
**Evidence:**
- **Broken:** `SelectDBConfig` lacks `Serializable` implementation
-
`seatunnel-connectors-v2/connector-selectdb-cloud/src/main/java/org/apache/seatunnel/connectors/selectdb/config/SelectDBConfig.java`
- **Working (references):** Similar connectors correctly implement
`Serializable`
-
`seatunnel-connectors-v2/connector-doris/src/main/java/org/apache/seatunnel/connectors/doris/config/DorisSinkConfig.java`
-
`seatunnel-connectors-v2/connector-starrocks/src/main/java/org/apache/seatunnel/connectors/starrocks/config/SinkConfig.java`
**Workaround:** Downgrade to 2.3.3 until the fix is released.
**To help us verify the exact trigger point:** Could you provide the full
error stack trace and confirm whether you're using the multi-table sink feature?
