### Search before asking - [x] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Description tablet schema: `CREATE TABLE test.table_auto ( `id` int NOT NULL, `name` varchar(65533) NOT NULL, `TIME_STAMP` datetime NOT NULL ) ENGINE=OLAP DUPLICATE KEY(`id`) AUTO PARTITION BY RANGE (date_trunc(`TIME_STAMP`, 'week')) () DISTRIBUTED BY HASH(`id`) BUCKETS 10 PROPERTIES ( "replication_allocation" = "tag.location.default: 3", "min_load_replica_num" = "-1", "is_being_synced" = "false", "storage_medium" = "hdd", "storage_format" = "V2", "inverted_index_storage_format" = "V1", "light_schema_change" = "true", "disable_auto_compaction" = "false", "enable_single_replica_compaction" = "false", "group_commit_interval_ms" = "10000", "group_commit_data_bytes" = "134217728" );` Problem: After using the insert into statement to write data to the table_auto table in batches, the CPU of the BE node will rise to more than 85%. ### Solution 1. Optimize the calculation of date_trunc function. 2. There should also be room for optimization in the calculation of partition deduplication. ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
