what happend

env

• 2.1.2

CREATE TABLE `address` (
  `timestamp` DATE NOT NULL COMMENT '['0000-01-01', '9999-12-31']',
  `type` TINYINT NOT NULL COMMENT '[-128, 127]',
  `user_id` BIGINT NULL COMMENT '[-9223372036854775808, 9223372036854775807]'
) ENGINE=OLAP
DUPLICATE KEY(`timestamp`, `type`)
COMMENT 'OLAP'
DISTRIBUTED BY HASH(`type`) BUCKETS 1
PROPERTIES (
"replication_allocation" = "tag.location.default: 1",
"min_load_replica_num" = "-1",
"is_being_synced" = "false",
"storage_medium" = "hdd",
"storage_format" = "V2",
"inverted_index_storage_format" = "V1",

"enable_single_replica_compaction" = "false",
"group_commit_interval_ms" = "10000",
"group_commit_data_bytes" = "134217728"
);

insert into address values('2023-07-19', 1, 1001)

 create table if not exists image PROPERTIES("replication_num"="1") as select * from address

select count(1) from image result is 1

create table if not exists image PROPERTIES("replication_num"="1") as select * from address

select count(1) from image result is 2

An INSERT operation was performed despite the table already existing.
The issue persists across both the new and legacy optimizers.
