Abstract: A method for query execution includes configuring, by at least one hardware processor, a materialized table (MT) based on the query and a base table. The MT includes a lag duration indicating a maximum time period that a result of a prior refresh of the query on the base table can lag behind a current time instance. The method further includes generating a query plan for the query. The method further includes determining multiple sets of data processing operations included in the query plan. The method further includes generating a plurality of intermediate MTs. The one or more intermediate MTs hold an intermediate processing state for the multiple sets of data processing operations. The method further includes configuring a refresh of the MT based on the intermediate processing state for the multiple sets of data processing operations.
