The latest iteration of Lucandra, called Solandra, creates localized
sub-indexes of size N and spreads them around the cassandra ring. Then using
solr, will behind the scenes search all the subindexes in parallel. This
approach should give you what you need and it would be great to have such a

My use case is that I have a trillion URIs to index with Lucene. Each URI is
either a resource or literal in an RDF graph. Each URI is a document for Lucene
If I were using Lucene, my understanding is that it would create a segment,

Lucene trades on (32-bit) ints internally, so I expect you're just seeing a
projection of that limitation.

I was reviewing the Lucandra schema presented on the below page at Datastax:

In the TermInfo Super Column Family, docID is the key for a supercolumn. Does

Hi Maxim,
Lucandra doesn't support numeric queries quite yet. A workaround would
be to load your numbers and convert them to strings.
I'll eventually add support for this. Please feel free to help out if
you can :)

Hello!
I am trying to rework our current lucene-based application to lucandra.
Note the following problem: when I try to use NumericRangeQuery like
this one:
query.add(NumericRangeQuery.newLongRange("deliveryTimestampMinute", 6,
fromDate, toDate, true, true), BooleanClause.Occur.
Oops. No crawler. My mistake.

Is there a way to not use the Solr's web crawler (we have our own) and just
use Solr for indexing and serving content?

I created a web crawler using Cassandra as the datastore and push to a bunch

It's very mature. You should also look at ElasticSearch. Much better
distribution model.

Solr looks like exactly what I want! How mature is it?

We're thinking of using Lucandra. We already use Lucene, but not in a
production-level environment, and we are concerned about the problem of
distributing Lucene over multiple servers. Lucandra seems like an obvious
solution to this problem.
Any comments or advice?

We looking into migrating from a replicated solr infrastructure to some
form of clustered approach. Lucandra looks fantastic -- but this
statement is troubling:
"No normalizations are stored (no scoring)" from
http://github.com/tjake/Lucandra
When I use the demo/samples get do get a
Lucandra spreads the data randomly by index + field combination so you do
get "some" distribution for free. Otherwise you can use "nodetool
loadbalance" to alter the token ring to alleviate hotspots.

If you worked with Lucandra in a dedicated searching-purposed cluster, you

I think Lucandra is really a great idea, but since it needs
order-preserving-partitioner, does that mean there may be some 'hot-spot'
during searching?
Hi,
What doesn't work with lucandra exactly? Feel free to msg me.

I will explore Lucandra a little more and if I can't get it to work today, I
will go for Option 2.
Using SQL will not be efficient in the future, if my website grows.

Rolling your own indexes is fairly common with Cassandra.

I red about Lucandra and seems interesting, but I couldn't run the examples,
I don't know if it is a good idea to use it and to be honest, I don't know
where to start
