CumulusRDF Detail

[ฌานุวรรษ อัศวเมนะกุล]

Hi,

I have the question about software detail.

What is the language that use to implementation CumulusRDF?

Is it have the ACID properties?

What is the indexing that it use?

What is the partitioning method that it use?

What is the replication method that it use?

Is it use MapReduce processing?

Thank you,

Chanuwas

Java (current downloadable version uses 1.6 while next version 1.1.0 uses 1.7)

No, transactions are not supported.

Please clarify this question...what do you mean with "indexing"? CumulusRDF uses Cassandra as underlying storage..is that close to what you were asking for?

CumulusRDF itself doesn't use a partition method...for those low level operations it relies on the underlying storage (i.e. Apache Cassandra)

> What is the replication method that it use?

If you meant "factor" that is configurable and depends on your cluster topology. If you instead meant "method" then it uses the replication mechanism of the underlyjng storage (i.e. Apache Cassandra)

MR is something that has to do with "data usage" while CumulusRDF is an RDF adapter on top of Apache Cassandra. Having said that, once you have your RDF data in Cassandra you can use MR jobs.
