Excuse my doubel-posting and replying to my own thread.
I found this in PBClientAdapter class in fetchIndex method
final MapReduce mr = new IndexMapReduce(this, indexQuery);
mr.addReducePhase(NamedErlangFunction.REDUCE_IDENTITY,
Args.REDUCE_PHASE_ONLY_1);
// only return the key, to match the http rest api
mr.addReducePhase(new JSSourceFunction("function(v) { return
v.map(function(e) { return e[1]; }); }"), Args.REDUCE_PHASE_ONLY_1);
This means it uses map reduce and JavaScript for protocol buffers.
Would that be the reason of slow performance with thousands of keys?
In my case it more performant to list all the keys than do 2i query.
I'm using java client 1.0.4 and riak cluster 1.1.1
Any feedback appreciated.
Daniel
