Description

Currently, if a table fails to dump data to Paimon within 2 minutes due to various reasons (network issues, Paimon service exceptions, etc.), the data on local disk will still be deleted when TTL expires, which may cause data loss.

Current Behavior

• Local disk data is deleted strictly according to TTL expiration time
• Data will be deleted even if tiering (dumping to Paimon) has not completed
• This may lead to data loss risk

Expected Behavior

• Local disk data should only be deleted according to TTL after successful tiering (dumping to Paimon)
• If data has not completed tiering, it should be retained even after TTL expiration until tiering is complete
