ASF GitHub Bot commented on JENA-624: ------------------------------------- Github user afs commented on the pull request: https://github.com/apache/jena/pull/94#issuecomment-155580382 Looks good. Time to think about merging. This is a significant contribution so I'll send a message to dev@ and formally let people know it is happening with lazy consensus. > Develop a new in-memory RDF Dataset implementation > -------------------------------------------------- > > Key: JENA-624 > URL: https://issues.apache.org/jira/browse/JENA-624 > Project: Apache Jena > Issue Type: Improvement > Reporter: Andy Seaborne > Assignee: A. Soroka > Labels: gsoc, gsoc2015, java, linked_data, rdf > > The current (Jan 2014) Jena in-memory dataset uses a general purpose > container that works for any storage technology for graphs together with > in-memory graphs. > This project would develop a new implementation design specifically for RDF > datasets (triples and quads) and efficient SPARQL execution, for example, > using multi-core parallel operations and/or multi-version concurrent > datastructures to maximise true parallel operation. > This is a system project suitable for someone interested in datatbase > implementation, datastructure design and implementation, operating systems or > distributed systems. > Note that TDB can operate in-memory using a simulated disk with > copy-in/copy-out semantics for disk-level operations. It is for faithful > testing TDB infrastructure and is not designed performance, general in-memory > use or use at scale. While lesson may be learnt from that system, TDB > in-memory is not the answer here. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
