> currently if multiple partition table，would cause oom easy
> eg:
> CREATE TABLE {{{}hudi_test{}}}.{{{}tmp_hudi_test_1{}}} (
> {{id}} string,
> {{name}} string,
> {{dt}} bigint,
> {{day}} STRING COMMENT '日期分区',
> {{hour}} INT COMMENT '小时分区'
> )using hudi
> OPTIONS ('hoodie.datasource.write.hive_style_partitioning' 'false',
> 'hoodie.datasource.meta.sync.enable' 'false',
> 'hoodie.datasource.hive_sync.enable' 'false')
> tblproperties (
> 'primaryKey' = 'id',
> 'type' = 'mor',
> 'preCombineField'='dt',
> 'hoodie.index.type' = 'BUCKET',
> 'hoodie.bucket.index.hash.field' = 'id',
> 'hoodie.bucket.index.num.buckets'=512
> )
> PARTITIONED BY ({{{}day{}}},{{{}hour{}}});
> select count(1) from {{{}hudi_test{}}}.{{{}tmp_hudi_test_1{}}} where
> day='2023-10-17' would list much filestatus to driver，and driver would
> oom（such as table with hundreds billion records in a
> partition（day='2023-10-17'））
