Riak Search performance experiences ?

Hi Neville,

Thanks! Performance comparisons are tricky business. Any time you compare a
distributed system to a non-distributed system on a single machine, the
non-distributed system is going to be much, much faster simply because it
can skip all of the overhead needed to make the system distributed.

So for 1M 1K docs, which can easily fit on one machine, Lucene will be much
faster. A more apples-to-apples question, and one we haven't benchmarked
yet, is how Riak Search compares to something like ElasticSearch. I expect
each system to have it's own unique strengths and weaknesses depending on
the type of documents, the ratio of reads-to-writes, the number of replicas,
and the type of failure scenarios that are tested.

We haven't done much comparison with distributed Lucene projects yet because
Riak Search is first and foremost intended to be a tightly integration index
into Riak KV data. The Solr interface is a nice bonus. It helps users
familiar with Solr get started with Riak Search more easily and it gives
users an additional way to access there data, so it is something we will
continue to enhance over future releases.

Best,
Rusty
