Paimon version

release-1.0

Compute Engine

spark-3.2.0

Minimal reproduce step

step 1： To create a date partitioned table, set 'metastore.partitioned-table' = 'false'
step 2： Write the test data of the last N days
step 3： CALL sys.expire_partitions(table => 'db.tb', expiration_time => '1 d', timestamp_formatter => 'yyyy-MM-dd');

What doesn't meet your expectations?

An exception is thrown when sys.expire_partitions is executed and no snapshot is generated, so the partitions that need to expire after the snapshot expires will not be physically deleted.

Anything else?
