This paper shows that the standard hash join algo-rithm for disk-oriented databases (i GRACE) spends over 73% of its user time stalled on CPU cache misses, and ex-plores the use of prefetching to improve its cache perfor-mance. JOIN OPERATOR OUTPUT For a tuple r ∈ R and a tuple s ∈ S that match on join attributes, concatenate rand s together into a new tuple. a traditional database operation, a Grace hash-join. sportsman fulfillment The idea is to build an in-memory hash table for the first partition of R during the partitioning phase, without the need to write this partition to disk.
