Robert Muir commented on LUCENE-3801:
-------------------------------------
looking at the benchmarks again: I think there is an
"off-by-a-factor-of-one-thousand" on the benchmark.
I could not for the life of me figure out why these suggesters would have e.g.
220QPS, but I think instead
that the benchmark is wrong. So 200,000-210,000QPS compared to 220,000QPS
really cannot matter!
If the benchmark can really satisfy 50000 queries in 220 ms, thats no 226QPS!
I'll come back with a PairOutputs test in a bit to confirm the functionality
but I'm not going to worry
about 5%/10% performance here, thats crazy.

> Not sure we should do this, it costs 5-10% performance for WFSTSuggester.
> But maybe we can optimize something here, or maybe its just no big deal to us.
> Because in general, this could be pretty powerful, e.g. if you needed to
> store
> some custom stuff in the suggester, you could use pairoutputs, or whatever.
> And the possibility we might need shortestPaths for other cool things... at
> the
> least I just wanted to have the patch up here.
> I haven't tested this on pairoutputs... but i've tested it with e.g.
> FloatOutputs
> and other things and it works fine.
> I tried to minimize the generics violations, there is only 1 (cannot create
> generic array).
