Parallel Query, Broadcast distribution and TEMP space

When it comes to parallel operations there are fundamentally two data distribution methods between individual parallel (PX) server sets: hash-hash and broadcast distribution. Suppose that you are going to operate a parallel HASH JOIN between two full table scans using a Degree of Parallelism (DOP) of 2. 2.115 more words
