[GitHub] [incubator-doris] Gabriel39 commented on pull request #9432: [Feature]Use multi hash tables to aggregate

   I still think we should have a detailed analysis on this.
   I have some questions for SSB Flat 100G
   1. fill factor and conflict factor in agg hash table (maybe an estimate value).
   2. data characteristics. （such as data size and order）
   
   I think there is a strong correlation between performance and workload. So we should take carefully to avoid potential performance fallback for other workloads.
