我有一个 3000w 行的数据表，我需要在这个表上统计从某一年开始新参保的人数，原数据库是 ORACLE ，用的是

AND A.AAC001 NOT EXISTS
(SELECT 1
FROM AC02_TEMP AS B WHERE A.AAC001 = B.AAC001 AND
B.AAC030 < '2018-01-01 00:00:00')

的语法,在 clickhouse 上我试了 LEFT JOIN 和 NOT IN ，性能均不理想

SELECT COUNT(1)  AS "新参保人数"
FROM AC02_TEMP AS A
WHERE A.AAB301 IN (SELECT AAB301 FROM AA26 WHERE AAA148 = '130800')
AND A.AAE200 = '41'
AND A.AAC031 = '1'
AND A.AAC030 >= '2018-01-01 00:00:00'
AND A.AAC001 NOT IN
(SELECT B.AAC001
FROM AC02_TEMP AS B
WHERE B.AAC030 < '2018-01-01 00:00:00');

以下是 explain

CreatingSets (Create sets before main query execution)
  Expression ((Projection + Before ORDER BY))
    Aggregating
      Expression (Before GROUP BY)
        ReadFromMergeTree (default.AC02_TEMP)
        Indexes:
          PrimaryKey
            Keys: 
              AAC001
              AAE200
"            Condition: and((AAC001 notIn 18692488-element set), (AAE200 in ['41', '41']))"
            Parts: 2/2
            Granules: 4821/4821
  CreatingSet (Create set for subquery)
    Expression ((Projection + Before ORDER BY))
      ReadFromMergeTree (default.AA26)
      Indexes:
        PrimaryKey
          Condition: true
          Parts: 1/1
          Granules: 1/1

我是 clickhouse 新手，目前没什么头绪，求大佬帮助 0.0
