Scaling Equi-Joins

Summary: AM-Join fuses Tree-Join and Broadcast-Join to scale equi-joins in shared-nothing systems, addressing join-key skew with robust load balancing. It supports all outer-join variants without deduplication or custom partitioning; IB-Join enables Small-Large outer-joins by keeping the small table in memory, with a Spark-based implementation delivering notable speedups.
