Generator is a base interface that defines the minimum methods needed to
implement a concrete generator. The reason for creating this interface is
eventually JMeter could use the logs directly rather than pre- process the
logs into a JMeter .jmx file. In situations where a test plan simulates load
from production logs, it is more efficient for JMeter to use the logs
directly.
From first hand experience, loading a test plan with 10K or more Requests
requires a lot of memory. It's important to keep in mind this type of testing
is closer to functional and regression testing than the typical stress tests.
Typically, this kind of testing is most useful for search sites that get a
large number of requests per day, but the request parameters vary
dramatically. E-commerce sites typically have limited inventory, therefore it
is better to design test plans that use data from the database.
