使用Google BigQuery执行查询时超出的资源

Question

在执行此查询时，我遇到了"Resources exceeded during query execution"错误:

SELECT date_time,Atok,Segment,
COUNT(Distinct GoogId) AS DistUsers,
SUM(CASE WHEN EventType=1 THEN 1 ELSE 0 END) AS CntImp,
SUM(CASE WHEN EventType=2 THEN 1 ELSE 0 END) AS CntClick,
SUM(CASE WHEN EventType=3 THEN 1 ELSE 0 END) AS CntVisit,
SUM(CASE WHEN EventType=4 THEN 1 ELSE 0 END) AS CntConv,
FROM LogData.unified_logs
GROUP EACH BY 1,2,3;

任何想法?

Count distinct是罪魁祸首…您应该能够创建一个子查询，它执行一个额外的组(每个)，计算不同的用户。
