The join is a three-column join between a large fact table (~1.2B rows/day) and a smaller dimension table (~300K rows). The size of a single day of compressed source files is ~4.2GB; decompressed is ~120GB. When performing a regular join (in Hive parlance âcommon joinâ), the join managed to create ~230GB of intermediary files. On a 4-node HDInsight on Azure cluster, taking a 1/6th sample of the large table for a single day of data, the query took 2h 24min. SELECT.
