Handle Sum0 when rebuilding materialized view incrementally

    XMLWordPrintableJSON

    Details

      Description

      When rewriting MV insert overwrite plan to incremental rebuild plan a Sum0 aggregate function is used when aggregating count function subresults coming from the existing MV data and the aggregated newly inserted/deleted records since the last rebuild

      create materialized view mat1 stored as orc TBLPROPERTIES ('transactional'='true') as
      select t1.a, count(*) from t1
      

      Insert overwrite plan:

      HiveAggregate(group=[{0}], agg#0=[$SUM0($1)])
        HiveUnion(all=[true])
          HiveAggregate(group=[{0}], agg#0=[count()])
            HiveProject($f0=[$0])
              HiveFilter(condition=[<(2, $5.writeid)])
                HiveTableScan(table=[[default, t1]], table:alias=[t1])
          HiveTableScan(table=[[default, mat1]], table:alias=[default.mat1])
      

      AssertionError when rewriting the plan to incremental rebuild
