[GitHub] [incubator-doris] blackfox1983 opened a new issue #2975: bitmap_count()返回内存过大导致客户端oom

blackfox1983 opened a new issue #2975: bitmap_count()返回内存过大导致客户端oom
URL: https://github.com/apache/incubator-doris/issues/2975
 
 
   CREATE TABLE uv_bitmap (
   sub_trade_id int(11) NULL COMMENT "",
   trade_id int(11) NULL COMMENT "",
   course_id int(11) NULL COMMENT "",
   user_id bitmap BITMAP_UNION NOT NULL COMMENT ""
   ) ENGINE=OLAP
   AGGREGATE KEY(sub_trade_id, trade_id, course_id)
   COMMENT "OLAP"
   DISTRIBUTED BY HASH(sub_trade_id) BUCKETS 2
   PROPERTIES (
   "storage_type" = "COLUMN"
   ); |
   
   当运行： select bitmap_count(user_id) from uv_bitmap; 直接吧客户端内存打爆。
   
   这个应该是直接返回一行数据吧？不应该吃客户端内存的
   
   是不是哪儿理解的不对？
