Shai Erera commented on LUCENE-2159:
------------------------------------
This looks like a nice tool. But all it does is create multiple copies of the
same segment(s) right? So what exactly do you want to test with it? What
worries me is that we'll be multiplying the lexicon, posting lists, statistics
etc., therefore I'm not sure how reliable the tests will be (whatever they
are), except for measuring things related to large number of segments (like
merge performance). Am I right?
I also think this class better fits in benchmark rather than misc, as it's
really for perf. testing/measurements and not as a generic utility ... You can
create a Task out if it, like ExpandIndexTask which one can include in his
algorithm.
