Hyunsik Choi commented on HBASE-2433:
-------------------------------------
I think that interactive queries may be impossible because RDF queries commonly
perform joins and doing joins against large-scale RDF data sets needs MapReduce
jobs. But, MR is a batch processing and has too slow response time to provide
interactive queries. It would be good to target analytical processing on
large-scale RDF data.

> This is for scoping out the feature set and the design specifications for the
> RDF store over HBase and the query capability it will have. I'll be posting
> some initial ideas soon.
> The key goals for this layer are:
> 1. Scalability
> 2. Support for interactive queries (this one seems to be the biggest
> challenge)
> We would need to define the subset of queries we will support. We'll probably
> begin with SELECT queries.
