Abstract
Arrangements for partition handling for multi table scan semi join operations are provided. Partition information of a first logical relation may be determined. Partition information of a first physical operator may be determined based on the partition information of the first logical relation. The partition information of the first physical operator may be stored in a data structure which includes partition information of a fact table and of each reducer in a predefined sequence. Partition information of a second logical relation may be determined. The partition information of a second physical operator may be determined based on the partition information of the second logical relation and the partition information of the first physical operator. The partition information of the second physical operator may be stored in the data structure. Execution of the second physical operator may be performed using the stored partition information, skipping mappings between pairs of partitions.
