What's Wrong?

when create table by BUCKETS AUTO, An export with partitions exports all of the table's data

What You Expected?

An export with partitions exports only the data in the specified partition

How to Reproduce?

CREATE TABLEkec( timestampdatetime NULL COMMENT "时间" ) ENGINE=OLAP DUPLICATE KEY(timestamp) COMMENT "" PARTITION BY RANGE(timestamp)() DISTRIBUTED BY RANDOM BUCKETS AUTO PROPERTIES ( "dynamic_partition.enable" = "true", "dynamic_partition.time_unit" = "HOUR", "dynamic_partition.end" = "24", "dynamic_partition.prefix" = "p", "replication_num" = "2" )

You need to change the time and partition key： insert into kec values("2023-11-17 16:01:01"); insert into kec values("2023-11-17 17:01:01");

EXPORT TABLE kec PARTITION(p2023111717) TO "file:///tmp/" PROPERTIES ( "label" = "kec_p2023111717" );

SHOW EXPORT WHERE LABEL = "kec_p2023111717" ORDER BY StartTime DESC;
