Question

In HYBRIDJOIN, what is the advantage of the algorithm when dealing with intermittent streams compared to the original MESHJOIN?

a.

MESHJOIN is faster for intermittent streams

b.

HYBRIDJOIN processes intermittent streams without pausing

c.

Both MESHJOIN and HYBRIDJOIN pause for intermittent streams

d.

MESHJOIN leaves tuples unprocessed for an open-ended period in intermittent streams

Posted under Big Data Computing

Answer: (b).HYBRIDJOIN processes intermittent streams without pausing Explanation:In intermittent streams, HYBRIDJOIN processes without pausing, whereas the original MESHJOIN would pause and leave tuples unprocessed for an open-ended period.
