Question

How does the hash table in HYBRIDJOIN help in matching disk pages with stream tuples?

a.

It stores only disk pages.

b.

It generates stream tuples.

c.

It matches disk pages with all matching tuples in the queue.

d.

It loads disk pages into memory.

Posted under Big Data Computing

Answer: (c).It matches disk pages with all matching tuples in the queue. Explanation:The hash table in HYBRIDJOIN stores stream tuples and the addresses of the nodes in the queue corresponding to the tuples, allowing it to match disk pages with all matching tuples in the queue.
