Question

Which factor contributes to a bottleneck in the execution of stream-based joins?

a.

Fast arrival rates of data from data sources

b.

Slow arrival rates of data from data sources

c.

High disk I/O cost for the lookup table

d.

Low disk I/O cost for the lookup table

Posted under Big Data Computing

Answer: (c).High disk I/O cost for the lookup table Explanation:The bottleneck in stream-based join execution is often caused by the high disk I/O cost associated with the lookup table.
